Abstract:
1. A method for manufacturing a MOSgated device comprising: providing a semiconductive body of a first conductivity type; forming spaced insulating bodies of a first thickness over a first major surface of said semiconductive body; forming an insulation layer of a second thickness over said first major surface in areas between said spaced insulating bodies, said second thickness being thinner than said first thickness; forming a gate electrode on at least one side of each of said spaced insulating bodies, each gate electrode being disposed over at least a portion of a respective insulation layer; forming a body region of a second conductivity type in said semiconductive body; and forming regions of said first conductivity type in said body regions, each said regions of said first conductivity type being spaced from said semiconductive body by a channel region in said body region, said channel region being disposed under a respective insulation layer.
