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 … 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 … 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, … 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. The basic design is generally a line for the channel with the source and drain leaving it at … See more Gate material The primary criterion for the gate material is that it is a good conductor. Highly doped polycrystalline silicon is … See more WebThe term carrier mobility generally alludes to both electron and hole mobility in semiconductors. These parameters characterize how quickly an electron and/or hole moves through a metal or semiconductor when under the influence of an electric field.
