Abstract:
A semiconductor protection structure formed within a semiconductor device and comprising:a duality of active areas formed within a substrate surface and each including dopant impurities of a first polarity therein, said duality of active areas spaced apart and including a substrate region including dopant impurities of an opposite polarity therebetween, each active area bounded by an edge forming an interface between said active area and said substrate region; a first overlap film overlapping a first active area of said duality of active areas, and a second overlap film overlapping the second active area, each respective overlap film separated from said corresponding active area by a dielectric film interposed therebetween, and formed of one of a conductive material and a semiconductor material; a first conductive film electrically coupled to said first active area through a first plurality of contact openings, said first overlap film through at least one first opening, and an input/output terminal of said semiconductor device, and a second conductive film electrically coupled to said second active area through a second plurality of contact openings, said second overlap film through at least one second opening, and at least one of a power supply and a ground source.
