  • Patent number: 5204543
    Abstract: A semiconductor device comprises a substrate of a first conduction type defined by a major surface, a pair of conductive regions of a second conduction type formed in the substrate along the major surface, an intervening region of the first conduction type formed in the substrate between the pair of conductive regions so as to separate the pair of conductive regions from each other, a first insulator film provided on the substrate so as to cover the major surface thereof including the pair of conductive regions and the intervening region located therebetween, a first conductor layer provided so as to extend generally parallel to the major surface of the substrate with a separation from the first insulator film, the first conductor layer crossing a part of the intervening region at a level separated therefrom, a second conductor layer provided on the first insulator film at a level below the first conductor layer so as to cover at least the part of the intervening region which is crossed by the first conductor
