Abstract:
A semiconductor device of the present invention includes a semiconductor layer of a first conductivity type having a cell portion and an outer peripheral portion disposed around the cell portion, and a surface insulating film disposed in a manner extending across the cell portion and the outer peripheral portion, and in the cell portion, formed to be thinner than a part in the outer peripheral portion.

Claim (Index 26):
A semiconductor device, comprising:\n a semiconductor substrate made of a wide-bandgap semiconductor; a cell portion arranged at a center portion of the semiconductor substrate in a plan view; an outer peripheral portion surrounding the cell portion in a plan view; a plurality of gate trenches formed at the surface of the semiconductor substrate at the cell portion; a plurality of gate electrodes formed so as to be buried in the plurality of gate trenches; and a surface insulating film with a first thickness formed so as to cover the plurality of gate electrodes at the cell portion, and with a second thickness formed so as to cover the semiconductor substrate at the outer peripheral portion; a first source portion formed on/over the semiconductor substrate at the cell portion; a gate portion formed on/over the semiconductor substrate at the outer peripheral portion; a second source portion formed on/over the semiconductor substrate so as to surround the gate portion at the outer peripheral portion; and a slit region formed in a uniform width along the gate portion in a plan view, wherein the first thickness is thinner than the second thickness.
