The gate of a MOSFET is insulted from the other nodes by a layer of silicon dioxide, which is an insulator. 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 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 right angles and then bending back at right angles into the same direction as the channel. Sometimes three line segments are … See more Gate material The primary criterion for the gate material is that it is a good conductor.
