Abstract:
A method for manufacturing a compound semiconductor device includes: providing a semiconductor substrate that includes a foundation layer; forming a deep trench in the foundation layer; and filling the deep trench with a deep layer having a second conductive type and a limiting layer having the first conductive type. In the filling the deep trench, growth of the deep layer from a bottom of the deep trench toward an opening inlet of the deep trench and growth of the limiting layer from a side face of the deep trench are achieved by: dominant epitaxial growth of a second conductive type layer over a first conductive type layer on the bottom of the deep trench; and dominant epitaxial growth of the first conductive type layer over the second conductive type layer on the side face of the deep trench, based on plane orientation dependency of the compound semiconductor during epitaxial growth.

Claim (Index 4):
The method for manufacturing the compound semiconductor device according to  claim 1 , the method further comprising:\n forming the second conductive type layer that constitutes a part of the deep layer by ion implantation of second conductive type dopant into the bottom of the deep trench, wherein the filling the deep trench is performed after the forming the second conductive type layer, and the deep layer formed by the filling the deep trench includes the second conductive type layer formed by the ion implantation and a part formed by the epitaxial growth.
