Bidirectional lateral insulated gate bipolar transistor
摘要:
A bidirectional lateral insulated gate bipolar transistor (IGBT) includes two gate electrodes. The IGBT can conduct current in two directions. The IGBT relies on a RESURF operation to provide high voltage blocking in both directions. The IGBT is symmetrical, having N-type drift region in contact with an oxide layer. A P-type region is provided above the N-type-drift region, having a portion more heavily doped with P-type dopants. The RESURF operation can be provided by a buried oxide layer or by a P substrate or by a horizontal PN junction. The IGBT can be utilized in various power operations, including a matrix switch or a voltage source converter.
