Abstract
According to one embodiment, a semiconductor device includes a semiconductor substrate including an element region, a guard ring provided on an outer periphery of the element region and including a first interconnect and a first plug which electrically couples the first-interconnect and a first well region, a second interconnect provided above the first interconnect via a first insulating layer and non-electrically coupling to the first interconnect, and a first circuit coupled to the second interconnect. The first circuit detects one of a crack and a peeling of the guard ring in accordance with a break in the second interconnect or a short circuit between the second interconnect and the first interconnect.
