Abstract:
1. A lateral MOS device formed in a body having a surface and comprising: a semiconductor layer, of a first conductivity type; a drain region of a second conductivity type, formed in the semiconductor layer and facing the surface; a source region of said second conductivity type, formed in the semiconductor layer and facing the surface; a channel of said first conductivity type, formed in the semiconductor layer between said drain region and said source region and facing said surface; an insulated gate region, formed over said surface and overlying said channel region; and a conductive region electrically isolated from the source region and extending only on one side of said insulated gate region, on top of said drain region, but not on top of said insulated gate region, wherein said conductive region extends longitudinally along said insulated gate region and ends with a widened contact portion encompassing projecting structures and extending between said projecting structures and said insulated gate region, the projecting structures each electrically coupled to a metallization layer.
