Patent ID: 7230273

Claim:
A semiconductor device comprising: a plurality of semiconductor elements each including an active region made of a wide band-gap semiconductor and at least two electrode pads to which an operating voltage is applied, said plurality of semiconductor elements being operable independently of one another; a plurality of electrode terminals; a plurality of connection members for electrically connecting each of the electrode pads of each of a plurality of particular semiconductor elements, which are at least some of the plurality of semiconductor elements, to a corresponding one of the plurality of electrode terminals, and an isolation region serving as a Schottky diode for electrically isolating the plurality of semiconductor elements from one another, wherein said plurality of particular semiconductor elements operate in parallel with one another, and the plurality of semiconductor elements are formed on a common substrate, and at least one of the electrode pads of each of the semiconductor elements other than the particular semiconductor elements of the plurality of semiconductor elements is not electrically connected to either of the plurality of electrode terminals.
