CMOS inverter (a NOT logic gate). Complementary 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.

The fabrication process is performed in highly specialized semiconductor fabrication plants, also called foundries or "fabs", [1] with the central part being the "clean room". In more advanced semiconductor devices, such as modern 14/10/7 nm nodes, fabrication can take up to 15 weeks, with 11–13 weeks being the industry average. [2]
Illustration of FEOL (device generation in the silicon, bottom) and BEOL (depositing metalization layers, middle part) to connect the devices. CMOS fabrication process. The front end of line (FEOL) is the first portion of IC fabrication where the individual components (transistors, capacitors, resistors, etc.) are patterned in a semiconductor substrate. [1]
In 1988, an IBM research team led by Iranian engineer Bijan Davari fabricated a 180 nm dual-gate MOSFET using a CMOS process. [5] The 180 nm CMOS process was later commercialized by TSMC in 1998, [ 1 ] and then Fujitsu in 1999.
The "22 nm" node is the process step following 32 nm in CMOS MOSFET semiconductor device fabrication. The typical half-pitch (i.e., half the distance between identical features in an array) for a memory cell using the process is around 22 nm. [citation needed] It was first demonstrated by semiconductor companies for use in RAM in 2008.
All production "10 nm" processes are based on FinFET (fin field-effect transistor) technology, a type of multi-gate MOSFET technology that is a non-planar evolution of planar silicon CMOS technology. Samsung first started their production of "10 nm-class" chips in 2013 for their multi-level cell (MLC) flash memory chips, followed by their SoCs ...
The BEOL process deposits metalization layers on the silicion to interconnect the individual devices generated during FEOL (bottom). CMOS fabrication process. Back end of the line or back end of line (BEOL) is a process in semiconductor device fabrication that consists of depositing metal interconnect layers onto a wafer already patterned with devices.
