[0002] IGBT insulated gate bipolar transistor is a composite fully controlled voltage-driven power semiconductor device composed of BJT (bipolar transistor) and MOS (insulated gate field effect transistor). It has the advantages of high input impedance of MOSFET and low on-state voltage drop of GTR. The production process of IGBT module mainly involves the process of wafer bonding on ceramic substrate, wire bonding, pin insertion, glue dispensing and sealing.
