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]
A MOSFET is based on the modulation of charge concentration by a MOS capacitance between a body electrode and a gate electrode located above the body and insulated from all other device regions by a gate dielectric layer. If dielectrics other than an oxide are employed, the device may be referred to as a metal-insulator-semiconductor FET (MISFET).
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.
A nanowire MOSFET's current–voltage characteristic (left, using logarithmic y-axis) and a simulation of the electron density (right) forming a conductive inversion channel which connects at the ~0.45 V threshold voltage. Extremely little current flows below this voltage.
