Mosfet physical structure
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 Gate material The primary criterion for the gate material is that it is a good conductor.
