ABSTRACT:
A heterojunction semiconductor device includes a first Schottky contact layer made of a first semiconductor, a second Schottky contact layer made of a second semiconductor and a metal electrode. The first Schottky contact layer, the second Schottky contact layer and the metal electrode are laminated in this order on a semiconductor substrate or on a main structure of a semiconductor device laminated on a semiconductor substrate from the substrate side or from the main structure side. The first Schottky contact layer serves as a barrier layer toward the second Schottky contact layer, and a layer thickness of the second Schottky contact layer is greater than the mean free pass of carriers in the second Schottky contact layer.
