Some chip manufacturers, most notably IBM and Intel, use an alloy of silicon and germanium in MOSFET channels. [ citation needed ] Many semiconductors with better electrical properties than silicon, such as gallium arsenide , do not form good semiconductor-to-insulator interfaces, and thus are not suitable for MOSFETs.
Silicon carbide (SiC), also known as carborundum (/ ˌ k ɑːr b ə ˈ r ʌ n d əm /), is a hard chemical compound containing silicon and carbon. A wide bandgap semiconductor , it occurs in nature as the extremely rare mineral moissanite , but has been mass-produced as a powder and crystal since 1893 for use as an abrasive .

In 1965, C.W. Mueller and P.H. Robinson fabricated a MOSFET (metal–oxide–semiconductor field-effect transistor) using the silicon-on-sapphire process at RCA Laboratories. [40] Semiconductor device manufacturing has since spread from Texas and California in the 1960s to the rest of the world, including Asia, Europe, and the Middle East.
In September 2019, the company announced a $1 billion investment in a semiconductor manufacturing plant in Marcy, New York to build the world’s largest silicon carbide fabrication facility with a $500 million grant from New York State. [14] [15] [16] In March 2021, the company sold its LED Business to SMART Global Holdings for up to $300 ...
In semiconductor manufacturing, the International Roadmap for Devices and Systems defines the "5 nm" process as the MOSFET technology node following the "7 nm" node. In 2020, Samsung and TSMC entered volume production of "5 nm" chips, manufactured for companies including Apple, Huawei, Mediatek, Qualcomm and Marvell.
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.

MOSFET, showing gate (G), body (B), source (S), and drain (D) terminals. The gate is separated from the body by an insulating layer (pink).. The MOSFET (metal–oxide–semiconductor field-effect transistor) [1] is a type of insulated-gate field-effect transistor (IGFET) that is fabricated by the controlled oxidation of a semiconductor, typically silicon.
