ABSTRACT:
A vertical MOSFET transistor is formed in a body of semiconductor material having a surface. The transistor includes a buried conductive region of a first conductivity type; a channel region of a second conductivity type, arranged on top of the buried conductive region; a surface conductive region of the first conductivity type, arranged on top of the channel region and the buried conductive region; a gate insulation region, extending at the sides of and contiguous to the channel region; and a gate region extending at the sides of and contiguous to the gate insulation region.
