Abstract
An improved silicon carbide (SiC) super junction (SJ) MOSFET having at least two buried P-shield (BPS) regions facing each other for gate oxide electric-field and saturation current reductions is disclosed. The two BPS regions are spaced apart from a body region and formed either adjoining sidewalls or below a bottom of a P column region. Moreover, a saturation current pitching (SCP) structure formed in a Junction Field Effect Transistor (JFET) region sandwiched between the two BPS regions limits saturation current of the device in a forward conduction stage for the short-circuit capability improvement.
