Abstract:
A method of manufacturing a semiconductor device includes: preparing a semiconductor substrate provided with an ohmic-contact layer, a drift layer, and a high resistivity layer; forming an upper electrode having a contact area that is in contact with each of upper surfaces of the drift layer and the high resistivity layer, wherein an outer peripheral edge of the contact area is located on the high resistivity layer and the upper electrode is in Schottky contact with at least the drift layer; and forming a lower electrode being in ohmic contact with a lower surface of the ohmic-contact layer. In the semiconductor substrate, the drift layer is located on a first region of the upper surface of the ohmic-contact layer and the high resistivity layer is located on a second region of the upper surface of the ohmic-contact layer that surrounds the first region.

Claim (Index 6):
The method according to  claim 1 , wherein the preparing of the semiconductor substrate comprises:\n forming the drift layer by epitaxial growth on the first region and the second region of the upper surface of the ohmic-contact layer; removing, by etching, a part of the drift layer located on the second region; and forming the high resistivity layer by epitaxial growth on the second region of the upper surface of the ohmic-contact layer after the drift region is removed.
