Shielded Gate SiC Trench Power MOSFET with Ultra-Low Switching Loss
Keyword(s):
A shielded gate trench silicon carbide (SiC) metal oxide semiconductor field effect transistor (SG-TMOS) is proposed and investigated by simulation in this paper. The impact of shielded gate design in SG-TMOS on Miller charge (Qgd) as well as conduction resistance (Ron) are comprehensively discussed, showing a tradeoff between Qgdand Ron. Furthermore, the Huang’s Figure of Merit (HFOM) of the SG-TMOS with reasonable design of SG is reduced more than 20%, compared with the conventional trench MOSFET (C-TMOS). Therefore, the proposed SG-TMOS is a competitive next generation device structure for ultra-high switching speed SiC MOSFET.
