Abstract:
A compound semiconductor device includes a semiconductor substrate having a ground layer of a first conductivity type made of a compound semiconductor, a first conductivity type region formed at a corner portion of a bottom of a deep trench formed to the ground layer, and a deep layer of a second conductivity type formed in the deep trench so as to cover the first conductivity type region. A cross section of the first conductivity type region is a triangular shape or a rounded triangular shape in which a portion of the first conductivity type region being in contact with the deep layer is recessed to have a curved surface.

Claim (Index 8):
The production method of the compound semiconductor device according to  claim 6 , wherein\n the forming the first conductivity type region and the epitaxially growing the deep layer includes switching the introduction of the dopant gas including the first conductivity type dopant to the introduction of the dopant gas including the second conductivity type dopant before or after the introduction of the source gas of the compound semiconductor.
