CMOS

CMOS inverter (NOT logic gate)
NAND gate in CMOS logic
The physical layout of a NAND circuit. The larger regions of N-type diffusion and P-type diffusion are part of the transistors. The two smaller regions on the left are taps to prevent latchup.
Simplified process of fabrication of a CMOS inverter on p-type substrate in semiconductor microfabrication. Note: Gate, source and drain contacts are not normally in the same plane in real devices, and the diagram is not to scale.

Complementary metal–oxide–semiconductor (CMOS) /ˈsmɒs/ is a technology for constructing integrated circuits. CMOS technology is used in microprocessors, microcontrollers, static RAM, and other digital logic circuits. CMOS technology is also used for several analog circuits such as image sensors (CMOS sensor), data converters, and highly integrated transceivers for many types of communication. In 1963, while working for Fairchild Semiconductor, Frank Wanlass patented CMOS (US patent 3,356,858).
