Abstract:
A semiconductor device according to an embodiment includes: an insulating film formed on a voltage supporting region B; an overvoltage protection diode that includes an n-type semiconductor layer and a p-type semiconductor layer; conductor portions that are formed on the insulating film and are electrically connected to the overvoltage protection diode; and a high-potential portion arranged above the overvoltage protection diode via an insulating film. The p-type impurity concentration of the p-type semiconductor layer is lower than the n-type impurity concentration of the n-type semiconductor layer. In the reverse bias application state, the high-potential portion has a higher potential than a potential of the potential of the p-type semiconductor layer disposed directly under the high-potential portion.

Claim (Index 1):
A semiconductor device with principal current flowing from one principal surface to another principal surface of a semiconductor substrate,\n wherein the one principal surface of the semiconductor substrate includes an active region, and a voltage supporting region that surrounds the active region and contains a peripheral portion of the semiconductor substrate, and the semiconductor device comprises:\n a first insulating film formed on the voltage supporting region; \n an overvoltage protection diode that includes an n-type semiconductor layer and a p-type semiconductor layer that are alternately arranged on the first insulating film in a manner adjacent to each other; \n a plurality of conductor portions that are formed on the first insulating film, and are electrically connected to the overvoltage protection diode; \n a second insulating film that covers the overvoltage protection diode and the conductor portions; and \n a high-potential portion provided above the overvoltage protection diode with the second insulating film intervening therebetween, \n a p-type impurity concentration of the p-type semiconductor layer is lower than an n-type impurity concentration of the n-type semiconductor layer, and the high-potential portion has a higher potential than a potential of the p-type semiconductor layer disposed immediately under the high-potential portion in an inversely biased application state, wherein the high-potential portion is electrically connected to the conductor portions via a conductive connector formed on the second insulating film, wherein the conductive connector has one end electrically connected to the high-potential portion, and another end electrically connected to the conductor portions.
