MOSFET AND METHOD FOR MANUFACTURING MOSFET

摘要

A MOSFET includes: a silicon carbide (SiC) substrate having a main surface having an off angle of not less than 50° and not more than 65° relative to a {0001} plane; a semiconductor layer formed on the main surface of the SiC substrate; and an insulating film formed in contact with a surface of the semiconductor layer. The MOSFET has a sub-threshold slope of not more than 0.4 V/Decade.
