See also: Microcontroller and Microprocessor chronology ![]() There are various different types of MOS IC chips, which include the following. It is a 4-bit central processing unit (CPU), fabricated on a silicon-gate PMOS large-scale integration (LSI) chip with a 10 µm process. Chips Intel 4004 (1971), the first single-chip microprocessor. ![]() In 1967, Bell Labs researchers Robert Kerwin, Donald Klein and John Sarace developed the self-aligned gate (silicon-gate) MOS transistor, which Fairchild Semiconductor researchers Federico Faggin and Tom Klein used to develop the first silicon-gate MOS IC. It was a 20-bit shift register, developed by Robert Norman and Frank Wanlass. General Microelectronics later introduced the first commercial MOS integrated circuits in 1964, consisting of 120 p-channel transistors. The earliest experimental MOS IC to be demonstrated was a 16-transistor chip built by Fred Heiman and Steven Hofstein at RCA in 1962. These two factors, along with its rapidly scaling miniaturization and low energy consumption, led to the MOSFET becoming the most widely used type of transistor in IC chips. The Si– SiO 2 system possessed the technical attractions of low cost of production (on a per circuit basis) and ease of integration. Its advantage for integrated circuits was re-iterated by Dawon Kahng in 1961. In contrast to bipolar transistors which required 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. This was followed by the development of clean rooms to reduce contamination to levels never before thought necessary, and coincided with the development of photolithography which, along with surface passivation and the planar process, allowed circuits to be made in few steps.Ītalla realised that the main advantage of a MOS transistor was its ease of fabrication, particularly suiting it for use in the recently invented integrated circuits. Atalla used his surface passivation process to make the first working MOSFET with Dawon Kahng at Bell Labs. Planar process, developed by Jean Hoerni at Fairchild Semiconductor in early 1959, was critical to the invention of the monolithic integrated circuit chip by Robert Noyce later in 1959. The MOSFET is the most widely used type of transistor and the most critical device component in integrated circuit (IC) chips. See also: Integrated circuit, Invention of the integrated circuit, and Three-dimensional integrated circuit MOSFET devices are also applied in audio-frequency power amplifiers for public address systems, sound reinforcement, and home and automobile sound systems. Radio systems also use MOSFETs as oscillators, or mixers to convert frequencies. Radio-frequency amplifiers up to the UHF spectrum use MOSFET transistors as analog signal and power amplifiers. ![]() Discrete MOSFET devices are widely used in applications such as switch mode power supplies, variable-frequency drives, and other power electronics applications where each device may be switching thousands of watts. MOSFETs in integrated circuits are the primary elements of computer processors, semiconductor memory, image sensors, and most other types of integrated circuits. MOSFET scaling and miniaturization has been driving the rapid exponential growth of electronic semiconductor technology since the 1960s, and enable high-density integrated circuits (ICs) such as memory chips and microprocessors. It was the first truly compact transistor that could be miniaturized and mass-produced for a wide range of uses. It is the most common semiconductor device in digital and analog circuits, and the most common power device. The MOSFET is the basic building block of most modern electronics, and the most frequently manufactured device in history, with an estimated total of 13 sextillion (1.3 × 10 22) MOSFETs manufactured between 19. The voltage of the covered gate determines the electrical conductivity of the device this ability to change conductivity with the amount of applied voltage can be used for amplifying or switching electronic signals. The MOSFET (metal–oxide–semiconductor field-effect transistor) is a type of insulated-gate field-effect transistor (IGFET) that is fabricated by the controlled oxidation of a semiconductor, typically silicon. The gate is separated from the body by an insulating layer (pink). MOSFET, showing gate (G), body (B), source (S), and drain (D) terminals.
