A 0.63 mΩcm2 / 1170 V property was demonstrated in a 4H-SiC V-groove trench MOSFET with a super junction (SJ) structure. Successful results in SJ-VMOSFETs will inspire research on 600 to 1200 V class devices as their extreme high MOS channel mobilit

We developed V-groove trench gate SiC MOSFETs with grounded buried p+ regions. An effective reduction can be seen in the feedback capacitance (Crss) of static characteristics, and a fast switching performance was achieved. The grounded buried p+ regi

Reliability physics of silicon carbide (SiC) metal-oxide semiconductor field-effect transistor (MOSFET) is not sufficiently clear; therefore an accurate estimation method of lifetime has been strongly required. The relationship between the failure ti

We have demonstrated a new analysis method using a precise equivalent circuit of 3.3 kV 400 A full SiC modules and showed that the calculated waveforms well agree with the measured waveforms. We have also examined the current distribution in the modu

The influence of surface pit shape on 4H-SiC double implanted MOSFETs (DMOSFETs) reliability under a high temperature drain bias test has been investigated. Threading dislocations formed two types of pit shapes (deep pit and shallow pit) on an epitax

Two types of 4H-silicon carbide (SiC) MOSFETs are proposed in this paper. One is the novel designed V-groove trench MOSFET that utilizes the 4H-SiC (0-33-8) face for the channel region. The MOS interface using this face shows the extremely low interf
