Patent ID: 7019344

Claim:
A lateral drift vertical metal-insulted field effect transistor (LDVMISFET) formed in a widebandgap semiconductor comprising: one or more layers of the widebandgap semiconductor having a first conductivity and a first and a second surface; one or more layers of the widebandgap semiconductor having a second conductivity formed in contact with the first surface of the one or more layers of the first conductivity, including at least a resurf layer; a sub-source terminal formed in contact with the second surface of the one or more layers of the first conductivity; one or more mesa regions formed in contact with the resurf layer including a source terminal and a gate terminal; a drain region in contact with the resurf layer spaced apart from the mesa regions; a vertical conduction path in the mesa region; and a lateral current conduction path in the one or more layers of the second conductivity type between the mesa region and the Drain region.
