Transcription: The topic for this lesson is metal oxide semiconductor field effect transistors, MOSFETs. Metal oxide semiconductor FETs, or MOSFETs, do not have an actual PN junction. When a metal oxide is not used to insulate the gate in the device, it is known as an IGFET, insulated gate field effect transistor. However, the gate is insulated from the channel source to drain current path in both types. Most commonly for a MOSFET, this insulation is achieved by using a thin slice of metal as the gate instead of the usual piece of semiconductor crystal. This slice of metal is oxidized on the side that is pla ...
