The metal–oxide–semiconductor field-effect transistor (MOSFET, MOS-FET, or MOS FET) is a type of field-effect transistor (FET), most commonly fabricated by the controlled oxidation of silicon. It has an insulated gate, the voltage of which determines the conductivity of the device. This ability to change … See more The basic principle of this kind of transistor was first patented by Julius Edgar Lilienfeld in 1925. The structure resembling the MOS transistor was proposed by Bell scientists William Shockley See more Metal–oxide–semiconductor structure The traditional metal–oxide–semiconductor (MOS) structure is obtained by growing a layer of silicon dioxide (SiO 2) on top of a silicon substrate, commonly by thermal oxidation and depositing a … See more Digital integrated circuits such as microprocessors and memory devices contain thousands to millions to billions of integrated MOSFET transistors on each device, providing the basic switching functions required to implement logic gates and data storage. … See more Over the past decades, the MOSFET (as used for digital logic) has continually been scaled down in size; typical MOSFET channel lengths were once several micrometres, but modern integrated circuits are incorporating MOSFETs with channel lengths of … See more Usually the semiconductor of choice is silicon. Recently, some chip manufacturers, most notably IBM and Intel, have started using an alloy of silicon and germanium ( See more A variety of symbols are used for the MOSFET.
