The default operating system is Sailfish OS (previously Manjaro ARM , with Plasma Mobile as the user interface ). The device is a developer platform with open hardware specifications but with unfinished software. The target group of
214-492: A design flow that engineers use to design, verify, and analyze entire semiconductor chips. Some of the latest EDA tools use artificial intelligence (AI) to help engineers save time and improve chip performance. Integrated circuits can be broadly classified into analog , digital and mixed signal , consisting of analog and digital signaling on the same IC. Digital integrated circuits can contain billions of logic gates , flip-flops , multiplexers , and other circuits in
321-627: A fabrication facility (commonly known as a semiconductor fab ) can cost over US$ 12 billion to construct. The cost of a fabrication facility rises over time because of increased complexity of new products; this is known as Rock's law . Such a facility features: ICs can be manufactured either in-house by integrated device manufacturers (IDMs) or using the foundry model . IDMs are vertically integrated companies (like Intel and Samsung ) that design, manufacture and sell their own ICs, and may offer design and/or manufacturing (foundry) services to other companies (the latter often to fabless companies ). In
428-412: A microprocessor will have memory on the chip. (See the regular array structure at the bottom of the first image. ) Although the structures are intricate – with widths which have been shrinking for decades – the layers remain much thinner than the device widths. The layers of material are fabricated much like a photographic process, although light waves in the visible spectrum cannot be used to "expose"
535-665: A " keyboard bar " form factor, like the BlackBerry line, Windows Mobile smartphones, Palm Treos , and some of the Nokia Eseries . A few hid their full physical QWERTY keyboard in a sliding form factor , like the Danger Hiptop line. Some even had only a numeric keypad using T9 text input , like the Nokia Nseries and other models in the Nokia Eseries . Resistive touchscreens with stylus -based interfaces could still be found on
642-504: A "devices and services" company. Despite the growth of Windows Phone and the Lumia range (which accounted for nearly 90% of all Windows Phone devices sold), the platform never had significant market share in the key U.S. market, and Microsoft was unable to maintain Windows Phone's momentum in the years that followed, resulting in dwindling interest from users and app developers. After Balmer
749-736: A "smartphone" began as a prototype called "Angler" developed by Canova in 1992 while at IBM and demonstrated in November of that year at the COMDEX computer industry trade show. A refined version was marketed to consumers in 1994 by BellSouth under the name Simon Personal Communicator . In addition to placing and receiving cellular calls , the touchscreen-equipped Simon could send and receive faxes and emails . It included an address book, calendar, appointment scheduler, calculator, world time clock, and notepad, as well as other visionary mobile applications such as maps, stock reports and news. The IBM Simon
856-431: A 3.5" capacitive touchscreen with twice the common resolution of most smartphone screens at the time , and introduced multi-touch to phones, which allowed gestures such as "pinching" to zoom in or out on photos, maps, and web pages. The iPhone was notable as being the first device of its kind targeted at the mass market to abandon the use of a stylus, keyboard, or keypad typical of contemporary smartphones, instead using
963-465: A 6-inch display, 13 MP Sony IMX258 as the main camera, 8 MP Omnivision OV8858 as front camera and has a user-replaceable 3000 mAh Samsung J7 -series battery. The phone has hardware kill switches for shutting down network connections, microphone, speaker, and cameras. The device has pogo pins for attachable backs compatible with the original PinePhone. The device ships with Sailfish OS (previously Manjaro ARM, with Plasma Mobile as
1070-466: A common active area, but there was no electrical isolation to separate them from each other. The monolithic integrated circuit chip was enabled by the inventions of the planar process by Jean Hoerni and p–n junction isolation by Kurt Lehovec . Hoerni's invention was built on Carl Frosch and Lincoln Derick's work on surface protection and passivation by silicon dioxide masking and predeposition, as well as Fuller, Ditzenberger's and others work on
1177-542: A common substrate in a three-stage amplifier arrangement. Jacobi disclosed small and cheap hearing aids as typical industrial applications of his patent. An immediate commercial use of his patent has not been reported. Another early proponent of the concept was Geoffrey Dummer (1909–2002), a radar scientist working for the Royal Radar Establishment of the British Ministry of Defence . Dummer presented

#17330863070161284-439: A dependence on third-party sources providing applications for multiple platforms. The advantages of a design with software powerful enough to support advanced applications and a large capacitive touchscreen affected the development of another smartphone OS platform, Android , with a more BlackBerry-like prototype device scrapped in favor of a touchscreen device with a slide-out physical keyboard, as Google's engineers thought at
1391-526: A dual five-megapixel rear camera setup for spatial imaging, among the earliest mobile phones with more than one rear camera . The 2012 Samsung Galaxy S3 introduced the ability to capture photos using voice commands . Integrated circuit An integrated circuit ( IC ), also known as a microchip , computer chip , or simply chip , is a small electronic device made up of multiple interconnected electronic components such as transistors , resistors , and capacitors . These components are etched onto
1498-451: A few smartphones, like the Palm Treos , which had dropped their handwriting input after a few early models that were available in versions with Graffiti instead of a keyboard. The late 2000s and early 2010s saw a shift in smartphone interfaces away from devices with physical keyboards and keypads to ones with large finger-operated capacitive touchscreens. The first phone of any kind with
1605-491: A few square millimeters. The small size of these circuits allows high speed, low power dissipation, and reduced manufacturing cost compared with board-level integration. These digital ICs, typically microprocessors , DSPs , and microcontrollers , use boolean algebra to process "one" and "zero" signals . Among the most advanced integrated circuits are the microprocessors or " cores ", used in personal computers, cell-phones, etc. Several cores may be integrated together in
1712-404: A large capacitive touchscreen as the sole means of interaction, and led to the decline of earlier, keyboard- and keypad-focused platforms. Later, navigation keys such as the home , back , menu , task and search buttons have also been increasingly replaced by nonphysical touch keys, then virtual, simulated on-screen navigation keys, commonly with access combinations such as a long press of
1819-428: A large transistor count . The IC's mass production capability, reliability, and building-block approach to integrated circuit design have ensured the rapid adoption of standardized ICs in place of designs using discrete transistors. ICs are now used in virtually all electronic equipment and have revolutionized the world of electronics . Computers, mobile phones, and other home appliances are now essential parts of
1926-519: A large capacitive touchscreen was the LG Prada , announced by LG in December 2006. This was a fashionable feature phone created in collaboration with Italian luxury designer Prada with a 3" 240 x 400 pixel screen, a 2-Megapixel digital camera with 144p video recording ability, an LED flash , and a miniature mirror for self portraits. In January 2007, Apple Computer introduced the iPhone . It had
2033-464: A large touchscreen for direct finger input as its main means of interaction. The iPhone's operating system was also a shift away from older operating systems (which older phones supported and which were adapted from PDAs and feature phones ) to an operative system powerful enough to not require using a limited, stripped down web browser that can only render pages specially formatted using technologies such as WML , cHTML , or XHTML and instead ran
2140-408: A layer of material, as they would be too large for the features. Thus photons of higher frequencies (typically ultraviolet ) are used to create the patterns for each layer. Because each feature is so small, electron microscopes are essential tools for a process engineer who might be debugging a fabrication process. Each device is tested before packaging using automated test equipment (ATE), in
2247-481: A limited amount of cellular Internet access. PDA and mobile phone manufacturers competed in reducing the size of devices. The bulk of these smartphones combined with their high cost and expensive data plans, plus other drawbacks such as expansion limitations and decreased battery life compared to separate standalone devices, generally limited their popularity to " early adopters " and business users who needed portable connectivity. In March 1996, Hewlett-Packard released

#17330863070162354-752: A major partnership with Microsoft, under which it would exclusively use Windows Phone on all of its future smartphones, and integrate Microsoft's Bing search engine and Bing Maps (which, as part of the partnership, would also license Nokia Maps data) into all future devices. The announcement led to the abandonment of both Symbian, as well as MeeGo —a Linux-based mobile platform it was co-developing with Intel. Nokia's low-end Lumia 520 saw strong demand and helped Windows Phone gain niche popularity in some markets, overtaking BlackBerry in global market share in 2013. In mid-June 2012, Meizu released its mobile operating system, Flyme OS . Many of these attempts to compete with Android and iPhone were short-lived. Over
2461-428: A number of steps for the p–n junction isolation of transistors on a chip, MOSFETs required no such steps but could be easily isolated from each other. Its advantage for integrated circuits was pointed out by Dawon Kahng in 1961. The list of IEEE milestones includes the first integrated circuit by Kilby in 1958, Hoerni's planar process and Noyce's planar IC in 1959. The earliest experimental MOS IC to be fabricated
2568-420: A process known as wafer testing , or wafer probing. The wafer is then cut into rectangular blocks, each of which is called a die . Each good die (plural dice , dies , or die ) is then connected into a package using aluminium (or gold) bond wires which are thermosonically bonded to pads , usually found around the edge of the die. Thermosonic bonding was first introduced by A. Coucoulas which provided
2675-421: A rate predicted by Moore's law , leading to large-scale integration (LSI) with hundreds of transistors on a single MOS chip by the late 1960s. Following the development of the self-aligned gate (silicon-gate) MOSFET by Robert Kerwin, Donald Klein and John Sarace at Bell Labs in 1967, the first silicon-gate MOS IC technology with self-aligned gates , the basis of all modern CMOS integrated circuits,
2782-523: A redesigned user interface, support for gestures such as pinch-to-zoom, and a new web browser based on the same WebKit rendering engine used by the iPhone. The following year, RIM released BlackBerry OS 7 and new models in the Bold and Torch ranges, which included a new Bold with a touchscreen alongside its keyboard, and the Torch 9860—the first BlackBerry phone to not include a physical keyboard. In 2013, it replaced
2889-407: A reliable means of forming these vital electrical connections to the outside world. After packaging, the devices go through final testing on the same or similar ATE used during wafer probing. Industrial CT scanning can also be used. Test cost can account for over 25% of the cost of fabrication on lower-cost products, but can be negligible on low-yielding, larger, or higher-cost devices. As of 2022 ,
2996-416: A rotary knob ring around the lens and a tripod mount. While screen sizes have increased, manufacturers have attempted to make smartphones thinner at the expense of utility and sturdiness, since a thinner frame is more vulnerable to bending and has less space for components, namely battery capacity. The iPhone and later touchscreen-only Android devices together popularized the slate form factor , based on
3103-426: A semiconductor to modulate its electronic properties. Doping is the process of adding dopants to a semiconductor material. Since a CMOS device only draws current on the transition between logic states , CMOS devices consume much less current than bipolar junction transistor devices. A random-access memory is the most regular type of integrated circuit; the highest density devices are thus memories; but even
3210-859: A single IC or chip. Digital memory chips and application-specific integrated circuits (ASICs) are examples of other families of integrated circuits. In the 1980s, programmable logic devices were developed. These devices contain circuits whose logical function and connectivity can be programmed by the user, rather than being fixed by the integrated circuit manufacturer. This allows a chip to be programmed to do various LSI-type functions such as logic gates , adders and registers . Programmability comes in various forms – devices that can be programmed only once , devices that can be erased and then re-programmed using UV light , devices that can be (re)programmed using flash memory , and field-programmable gate arrays (FPGAs) which can be programmed at any time, including during operation. Current FPGAs can (as of 2016) implement
3317-532: A single die. A technique has been demonstrated to include microfluidic cooling on integrated circuits, to improve cooling performance as well as peltier thermoelectric coolers on solder bumps, or thermal solder bumps used exclusively for heat dissipation, used in flip-chip . The cost of designing and developing a complex integrated circuit is quite high, normally in the multiple tens of millions of dollars. Therefore, it only makes economic sense to produce integrated circuit products with high production volume, so

Radios with the Loewe 3NF were less expensive than other radios, showing one of the advantages of integration over using discrete components , that would be seen decades later with ICs. Early concepts of an integrated circuit go back to 1949, when German engineer Werner Jacobi ( Siemens AG ) filed a patent for an integrated-circuit-like semiconductor amplifying device showing five transistors on
3638-512: A small piece of semiconductor material, usually silicon . Integrated circuits are used in a wide range of electronic devices, including computers , smartphones , and televisions , to perform various functions such as processing and storing information. They have greatly impacted the field of electronics by enabling device miniaturization and enhanced functionality. Integrated circuits are orders of magnitude smaller, faster, and less expensive than those constructed of discrete components, allowing

By the mid-2020s, manufacturers began integrating satellite messaging and emergency services, expanding their utility in remote areas without reliable cellular coverage . Following the rising popularity of the iPhone in the late 2000s, the majority of smartphones have featured thin, slate-like form factors with large, capacitive touch screens with support for multi-touch gestures rather than physical keyboards. Most modern smartphones have
3852-571: A version of Apple's Safari browser that could render full websites not specifically designed for mobile phones. Later Apple shipped a software update that gave the iPhone a built-in on-device App Store allowing direct wireless downloads of third-party software. This kind of centralized App Store and free developer tools quickly became the new main paradigm for all smartphone platforms for software development , distribution , discovery, installation , and payment, in place of expensive developer tools that required official approval to use and
3959-505: A year after Kilby, Robert Noyce at Fairchild Semiconductor invented the first true monolithic IC chip. More practical than Kilby's implementation, Noyce's chip was made of silicon , whereas Kilby's was made of germanium , and Noyce's was fabricated using the planar process , developed in early 1959 by his colleague Jean Hoerni and included the critical on-chip aluminum interconnecting lines. Modern IC chips are based on Noyce's monolithic IC, rather than Kilby's. NASA's Apollo Program

Smartphone A smartphone , often simply called a phone , is a mobile device that combines the functionality of a traditional mobile phone with advanced computing capabilities. It typically has a touchscreen interface, allowing users to access a wide range of applications and services, such as web browsing , email , and social media , as well as multimedia playback and streaming . Smartphones have built-in cameras , GPS navigation , and support for various communication methods, including voice calls, text messaging , and internet-based messaging apps. Smartphones are distinguished from older-design feature phones by their more advanced hardware capabilities and extensive mobile operating systems , access to
4173-444: Is low because the chips, with all their components, are printed as a unit by photolithography rather than being constructed one transistor at a time. Furthermore, packaged ICs use much less material than discrete circuits. Performance is high because the IC's components switch quickly and consume comparatively little power because of their small size and proximity. The main disadvantage of ICs
4280-681: Is obsolete. An early attempt at combining several components in one device (like modern ICs) was the Loewe 3NF vacuum tube first made in 1926. Unlike ICs, it was designed with the purpose of tax avoidance , as in Germany, radio receivers had a tax that was levied depending on how many tube holders a radio receiver had. It allowed radio receivers to have a single tube holder. One million were manufactured, and were "a first step in integration of radioelectronic devices". The device contained an amplifier , composed of three triodes, two capacitors and four resistors in
4387-413: Is the high initial cost of designing them and the enormous capital cost of factory construction. This high initial cost means ICs are only commercially viable when high production volumes are anticipated.

By the mid-2000s, higher-end cell phones commonly had integrated digital cameras. In 2003 camera phones outsold stand-alone digital cameras, and in 2006 they outsold film and digital stand-alone cameras. Five billion camera phones were sold in five years, and by 2007 more than half of

Phones built by Japanese manufacturers used custom firmware , however, and did not yet feature standardized mobile operating systems designed to cater to third-party application development , so their software and ecosystems were akin to very advanced feature phones . As with other feature phones, additional software and services required partnerships and deals with providers. The degree of integration between phones and carriers, unique phone features, non-standardized platforms, and tailoring to Japanese culture made it difficult for Japanese manufacturers to export their phones, especially when demand

The Altek Leo, a 14-megapixel smartphone with 3x optical zoom lens and 720p HD video camera was released in late 2010. In 2011, the same year the Nintendo 3DS was released, HTC unveiled the Evo 3D , a 3D phone with
4922-551: The OmniGo 700LX , a modified HP 200LX palmtop PC with a Nokia 2110 mobile phone piggybacked onto it and ROM -based software to support it. It had a 640 × 200 resolution CGA compatible four-shade gray-scale LCD screen and could be used to place and receive calls, and to create and receive text messages, emails and faxes. It was also 100% DOS 5.0 compatible, allowing it to run thousands of existing software titles, including early versions of Windows . In August 1996, Nokia released

As part of a proposed divestment of its consumer business to focus on enterprise software, HP abruptly ended development of future webOS devices in August 2011, and sold the rights to webOS to LG Electronics in 2013, for use as a smart TV platform. Research in Motion introduced the vertical-sliding BlackBerry Torch and BlackBerry OS 6 in 2010, which featured
5136-476: The dual in-line package (DIP), first in ceramic and later in plastic, which is commonly cresol - formaldehyde - novolac . In the 1980s pin counts of VLSI circuits exceeded the practical limit for DIP packaging, leading to pin grid array (PGA) and leadless chip carrier (LCC) packages. Surface mount packaging appeared in the early 1980s and became popular in the late 1980s, using finer lead pitch with leads formed as either gull-wing or J-lead, as exemplified by
5243-479: The installed base of all mobile phones were camera phones. Sales of separate cameras peaked in 2008. Many early smartphones did not have cameras at all, and earlier models that had them had low performance and insufficient image and video quality that could not compete with budget pocket cameras and fulfill user's needs. By the beginning of the 2010s almost all smartphones had an integrated digital camera. The decline in sales of stand-alone cameras accelerated due to

Smartphones typically feature metal–oxide–semiconductor (MOS) integrated circuit (IC) chips, various sensors, and support for multiple wireless communication protocols. These devices leverage sensors such as accelerometers , barometers , gyroscopes , and magnetometers , which can be used by both pre-installed and third-party software to enhance functionality. In addition, smartphones are equipped to support
5457-488: The non-recurring engineering (NRE) costs are spread across typically millions of production units. Modern semiconductor chips have billions of components, and are far too complex to be designed by hand. Software tools to help the designer are essential. Electronic design automation (EDA), also referred to as electronic computer-aided design (ECAD), is a category of software tools for designing electronic systems , including integrated circuits. The tools work together in

#17330863070165564-498: The periodic table of the chemical elements were identified as the most likely materials for a solid-state vacuum tube . Starting with copper oxide , proceeding to germanium , then silicon , the materials were systematically studied in the 1940s and 1950s. Today, monocrystalline silicon is the main substrate used for ICs although some III-V compounds of the periodic table such as gallium arsenide are used for specialized applications like LEDs , lasers , solar cells and
5671-544: The small-outline integrated circuit (SOIC) package – a carrier which occupies an area about 30–50% less than an equivalent DIP and is typically 70% thinner. This package has "gull wing" leads protruding from the two long sides and a lead spacing of 0.050 inches. In the late 1990s, plastic quad flat pack (PQFP) and thin small-outline package (TSOP) packages became the most common for high pin count devices, though PGA packages are still used for high-end microprocessors . Ball grid array (BGA) packages have existed since
5778-416: The switching power consumption per transistor goes down, while the memory capacity and speed go up, through the relationships defined by Dennard scaling ( MOSFET scaling ). Because speed, capacity, and power consumption gains are apparent to the end user, there is fierce competition among the manufacturers to use finer geometries. Over the years, transistor sizes have decreased from tens of microns in
5885-503: The very large-scale integration (VLSI) of more than 10,000 transistors on a single chip. At first, MOS-based computers only made sense when high density was required, such as aerospace and pocket calculators . Computers built entirely from TTL, such as the 1970 Datapoint 2200 , were much faster and more powerful than single-chip MOS microprocessors such as the 1972 Intel 8008 until the early 1980s. Advances in IC technology, primarily smaller features and larger chips, have allowed
5992-475: The " Pocket PC " versions of what was later Windows Mobile , and the UIQ interface that was originally designed for pen-based PDAs on Symbian OS devices resulted in some early smartphones having stylus-based interfaces. These allowed for virtual keyboards and handwriting input, thus also allowing easy entry of Asian characters. By the mid-2000s, the majority of smartphones had a physical QWERTY keyboard. Most used

The wafer need not be entirely silicon. Photolithography is used to mark different areas of the substrate to be doped or to have polysilicon, insulators or metal (typically aluminium or copper) tracks deposited on them. Dopants are impurities intentionally introduced to

Kilby won the 2000 Nobel Prize in physics for his part in the invention of the integrated circuit. However, Kilby's invention was not a true monolithic integrated circuit chip since it had external gold-wire connections, which would have made it difficult to mass-produce. Half
6848-427: The course of the decade, the two platforms became a clear duopoly in smartphone sales and market share, with BlackBerry, Windows Phone, and other operating systems eventually stagnating to little or no measurable market share. In 2015, BlackBerry began to pivot away from its in-house mobile platforms in favor of producing Android devices, focusing on a security-enhanced distribution of the software. The following year,

In the middle of 2022, the software stack was under development, resulting in the hardware not supporting the software. The first images from the camera were taken in May 2022. Most widely-supported hardware is in a heavily patched downstream kernel called Megi kernel. There
7062-473: The desktop Datapoint 2200 were built from bipolar integrated circuits, either TTL or the even faster emitter-coupled logic (ECL). Nearly all modern IC chips are metal–oxide–semiconductor (MOS) integrated circuits, built from MOSFETs (metal–oxide–silicon field-effect transistors). The MOSFET invented at Bell Labs between 1955 and 1960, made it possible to build high-density integrated circuits . In contrast to bipolar transistors which required

The materials and structures used in the path these electrical signals must travel have very different electrical properties, compared to those that travel to different parts of
7490-536: The diffusion of impurities into silicon. A precursor idea to the IC was to create small ceramic substrates (so-called micromodules ), each containing a single miniaturized component. Components could then be integrated and wired into a bidimensional or tridimensional compact grid. This idea, which seemed very promising in 1957, was proposed to the US Army by Jack Kilby and led to the short-lived Micromodule Program (similar to 1951's Project Tinkertoy). However, as
