High Voltage N-Channel Insulated Gate Bipolar Transistor (IGBT) in Silicon Carbide
- 总结
- A Purdue University researcher has developed a method and process for fabricating IGBTs in SiC. The method avoids the high resistance introduced from substrates in current manufacturing methods, while preserving the advantages of an N-type MOS channel.

- *Abstract
-
- *Background
- Insulated Gate Bipolar Transistors (IGBTs) combine the low drive characteristic of metal oxide semiconductor field effect transistors and the high power handling characteristic of bipolar transistors. These features make IGBTs ideal for high voltage switching applications. The use of silicon carbide as a process material yields IGBTs with even higher breakdown voltage capability, but introduces high parasitic series resistance.
