MOSFET, showing gate (G), body (B), source (S), and drain (D) terminals. The gate is separated from the body by an insulating layer (pink).. The MOSFET (metal–oxide–semiconductor field-effect transistor) [1] is a type of insulated-gate field-effect transistor (IGFET) that is fabricated by the controlled oxidation of a semiconductor, typically silicon.
If the MOSFET is an n-channel or nMOS FET, then the source and drain are n+ regions and the body is a p region. If the MOSFET is a p-channel or pMOS FET, then the source and drain are p+ regions and the body is a n region. The source is so named because it is the source of the charge carriers (electrons for n-channel, holes for p-channel) that ...
Enhancement-mode MOSFETs (metal–oxide–semiconductor FETs) are the common switching elements in most integrated circuits. These devices are off at zero gate–source voltage. NMOS can be turned on by pulling the gate voltage higher than the source voltage, PMOS can be turned on by pulling the gate voltage lower than the source voltage.

The MOSFET (metal–oxide–semiconductor field-effect transistor) utilizes an insulator (typically SiO 2) between the gate and the body. This is by far the most common type of FET. The DGMOSFET (dual-gate MOSFET) or DGMOS, a MOSFET with two insulated gates. The IGBT (insulated-gate bipolar transistor) is a device for power control. It has a ...
NXP 7030AL - N-channel TrenchMOS logic level FET IRF640 Power Mosfet die. The power MOSFET is the most widely used power semiconductor device in the world. [3] As of 2010, the power MOSFET accounts for 53% of the power transistor market, ahead of the insulated-gate bipolar transistor (27%), RF power amplifier (11%) and bipolar junction transistor (9%). [24]
The 180 nm process is a MOSFET semiconductor process technology that was commercialized around the 1998–2000 timeframe by leading semiconductor companies, starting with TSMC [1] and Fujitsu, [2] then followed by Sony, Toshiba, [3] Intel, AMD, Texas Instruments and IBM.
The 2N7000 is an N-channel, enhancement-mode MOSFET used for low-power switching applications. [ 1 ] The 2N7000 is a widely available and popular part, often recommended as useful and common components to have around for hobbyist use.
