RCA commercialized the technology with the trademark 'COS-MOS' in the late 1960s, forcing other manufacturers to find another name, leading to 'CMOS' becoming the standard name for the technology by the early 1970s. Wanlass later filed US patent 3,356,858 for CMOS circuitry and it was granted in 1967. The CMOS process was originally conceived by Frank Wanlass at Fairchild Semiconductor and presented by Wanlass and Chih-Tang Sah at the International Solid-State Circuits Conference in 1963. CMOS technology is also used for analog circuits such as image sensors ( CMOS sensors), data converters, RF circuits ( RF CMOS), and highly integrated transceivers for many types of communication. CMOS technology is used for constructing integrated circuit (IC) chips, including microprocessors, microcontrollers, memory chips (including CMOS BIOS), and other digital logic circuits. CMOS inverter (a NOT logic gate)Ĭomplementary metal–oxide–semiconductor ( CMOS, pronounced 'sea-moss', / s iː m ɑː s/, /- ɒ s/) is a type of metal–oxide–semiconductor field-effect transistor (MOSFET) fabrication process that uses complementary and symmetrical pairs of p-type and n-type MOSFETs for logic functions.
