Abstract:
1. A MOSgated device comprising: a semiconductor body of a first conductivity type; a channel region of a second conductivity type formed in said semiconductor body; a conductive region of said first conductivity type formed in said semiconductor body and extending from a first major surface of said semiconductor body to at least said channel region; a plurality of spaced trenches extending into said semiconductor body below said channel region, each of said trenches being adjacent a mesa and each terminating at a contact region in said semiconductor body, said channel region and said conductive region extending into said contact region, and said conductive region uninterruptedly extending between each two adjacently disposed trenches; a gate insulation layer dispose over the sidewalls and bottom of each of said trenches; a gate electrode formed in each of said trenches over said gate insulation layer; at least one conductive strip extending transverse to and over each of said trenches and electrically connected to each of said gate electrodes; said conductive strip being narrower than the length of said gate electrodes such that it makes contact only with a portion of each of said gate electrodes; and a remote contact formed over at least said contact region and in electrical contact with at least said conductive region.
