Abstract:
A semiconductor device with an embedded schottky diode and a manufacturing method thereof are provided. A semiconductor device having a schottky diode include: an epilayer of a first conductivity type, a body layer of a second conductivity type, and a source layer of the first conductivity type arranged in that order; a gate trench that extends from the source layer to a part of the epilayer; a body trench formed a predetermined distance from the gate trench and extends from the source layer to a part of the epilayer; and a guard ring of the second conductivity type that contacts an outer wall of the body trench and formed in the epilayer.

Claim (Index 2):
The method of  claim 1 , wherein the selectively etching the semiconductor device comprises:\n forming an etching mask on the semiconductor device; and etching the semiconductor device to the second depth by etching an area exposed by the etching mask, and wherein the semiconductor device further comprises an oxide layer disposed on the source layer.
