However, the practical difficulty of device fabrication has prevented from the wide use until 1960s. The igfet or mosfet is a voltage controlled field effect transistor that differs from a jfet in that it has a metal oxide gate electrode which is electrically insulated from the main semiconductor nchannel or pchannel by a very thin layer of insulating material usually silicon dioxide, commonly known as glass. Mosfet stands for metal oxide silicon field effect transistor or metal oxide semiconductor field effect transistor. The mosfet is very far the most common transistor and can be used in both analog and digital circuits. Hence comparing the schematic symbol to the pn junction in figure 4, we see the anode is the ptype semiconductor and the cathode is the ntype semiconductor. The transistor is a terminal device and the three terminals are base, emitter, and collector. Figure 1 shows the device schematic, transfer characteristics and device symbol for a mosfet. The invention of the power mosfet was partly driven by the limitations of bipolar power junction transistors bjts which, until recently, was the device of. If the transistor is a pnp, then the arrow points to the base of the transistor, otherwise it points to the output.
