A type of semiconductor field effect transistor used in integrated circuit technology that consumes very little power and can be highly miniaturized.
Short for metal-oxide semiconductor field effect transistor. A type of field effect transistor, used predominantly in microprocessor and related technology, that consumes very little power and can be highly miniaturized.
(Metal Oxide Semiconductor Field Effect Transistor) The most popular type of field effect transistor (see FET). MOSFETs are fabricated as a "discrete" transistor packaged individually for high power applications as well as chips with hundreds of millions of transistors.The "MO" in MOS and "FE" in FETThe "metal oxide" (MO) comes from the first devices that used a metal gate over oxide (silicon dioxide). Subsequently, poly-crystalline silicon was used for the gate, but MOS was never renamed. The "field-effect" (FE) is the electromagnetic field that is generated when the gate electrode is energized, causing the transistor to turn on or off.NMOS, PMOS and CMOSMOSFETs come in negative channel and positive channel varieties (see below). When NMOS and PMOS transistors are wired together, they become a CMOS (complementary MOS) gate, which causes no power to be used until the transistors switch. CMOS is the most widely used microelectronic design process and is found in almost every electronic product. See power MOSFET, n-type silicon, bipolar transistor, chip and FET.
