Abstract:
1. A DMOS device comprising: a body of semiconductor material of a first conductivity type and a first doping level, said body having a surface; a field region, of insulating material, extending along said surface and separating, in said body, at least one first active area and one second active area; a first conductive region with said first conductivity type and a second doping level, higher than said first doping level, formed in said first active area; a body region with a second conductivity type, formed in said second active area; a second conductive region with said first conductivity type, formed in said body region; at least one body-contact region, with said second conductivity type, formed inside said second conductive region and extending from said surface as far as said body region; an insulating layer, extending on top of said surface and having a plurality of contact openings; and
