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.

Listed are many semiconductor scale examples for various metal–oxide–semiconductor field-effect transistor (MOSFET, or MOS transistor) semiconductor manufacturing process nodes. Timeline of MOSFET demonstrations
TMOS fabrication is based on built - in masks and dry bulk micromachining. [1] [4] In TMOS fabrication to the standard CMOS - SOI technology, used to produce MOS transistor, is added a MEMS post process necessary to realize the folded arms and the suspension of the transistor. In standard CMOS process there are several metallization layers.
In semiconductor manufacturing, the 2 nm process is the next MOSFET (metal–oxide–semiconductor field-effect transistor) die shrink after the 3 nm process node.. The term "2 nanometer", or alternatively "20 angstrom" (a term used by Intel), has no relation to any actual physical feature (such as gate length, metal pitch or gate pitch) of the transistors.
In 1948, Bardeen patented an insulated-gate transistor (IGFET) with an inversion layer; Bardeen's concept forms the basis of MOSFET technology today. [34] An improved type of MOSFET technology, CMOS, was developed by Chih-Tang Sah and Frank Wanlass at Fairchild Semiconductor in 1963. [35] [36] CMOS was commercialised by RCA in the late 1960s. [35]
In semiconductor electronics fabrication technology, a self-aligned gate is a transistor manufacturing approach whereby the gate electrode of a MOSFET (metal–oxide–semiconductor field-effect transistor) is used as a mask for the doping of the source and drain regions. This technique ensures that the gate is naturally and precisely aligned ...
Important advances [4] include the addition of new instructions (including SSE4, also known as Penryn New Instructions) and new fabrication materials (most significantly a hafnium-based dielectric). Intel's 45nm process has a transistor density of 3.33 million transistors per square milimeter (MTr/mm2).
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 ...
