Shallow trench isolation ( STI ), also known as box isolation technique , is an integrated circuit feature which prevents electric current leakage between adjacent semiconductor device components. STI is generally used on CMOS process technology nodes of 250 nanometers and smaller. Older CMOS technologies and non-MOS technologies commonly use isolation based on LOCOS .

22-474: A larger number of passive elements ( capacitors , resistors , and inductors ) than digital chips. Inductors tend to be avoided because of their large physical size, and difficulties incorporating them into monolithic semiconductor ICs. Certain circuits such as gyrators can often act as equivalents of inductors, while constructed only from transistors and capacitors. Analog chips may also contain digital logic elements to replace some analog functions, or to allow
33-489: Is a stub . You can help Misplaced Pages by expanding it . Analog chip A linear integrated circuit or analog chip is a set of miniature electronic analog circuits formed on a single piece of semiconductor material. The voltage and current at specified points in the circuits of analog chips vary continuously over time. In contrast, digital chips only assign meaning to voltages or currents at discrete levels. In addition to transistors , analog chips often include
44-459: Is different from Wikidata All article disambiguation pages All disambiguation pages Shallow trench isolation STI is created early during the semiconductor device fabrication process, before transistors are formed. The key steps of the STI process involve etching a pattern of trenches in the silicon, depositing one or more dielectric materials (such as silicon dioxide ) to fill
55-453: The 741 operational amplifier , and the 555 timer IC . Power supply chips are also considered to be analog chips. Their main purpose is to produce a well-regulated output voltage supply for other chips in the system. Since all electronic systems require electrical power, power supply ICs ( power management integrated circuits , PMIC) are important elements of those systems. Important basic building blocks of analog chip design include: All
66-399: The electric field enhancement at the edge, it is easier to form a conducting channel (by inversion) at a lower voltage. The threshold voltage is effectively reduced for a narrower transistor width. The main concern for electronic devices is the resulting subthreshold leakage current, which is substantially larger after the threshold voltage reduction. This electronics-related article

88-441: The benefits of this mixed technology include load protection, reduced parts count, and higher reliability. Purely analog chips in information processing have been mostly replaced with digital chips. Analog chips are still required for wideband signals, high-power applications, and transducer interfaces. Research and industry in this specialty continues to grow and prosper. Some examples of long-lived and well-known analog chips are
99-404: The chip to communicate with a microprocessor . For this reason, and since logic is commonly implemented using CMOS technology, these chips typically use BiCMOS processes, as implemented by companies such as Freescale , Texas Instruments , STMicroelectronics , and others. This is known as "mixed signal processing", and allows a designer to incorporate more functions into a single chip. Some of
