ABSTRACT:
In a semiconductor device in which a diode and a high electron mobility transistor are incorporated in the same semiconductor chip, a compound semiconductor layer of the high electron mobility transistor is formed on a main surface (first main surface) of a semiconductor substrate of the diode, and an anode electrode of the diode is electrically connected to an anode region via a conductive material embedded in a via hole (hole) reaching a p+region which is the anode region of the main surface of the semiconductor substrate from a main surface of the compound semiconductor layer.
