Abstract
A semiconductor transistor device comprises a gate electrode disposed over an insulating surface, a spacer element located at the end of the gate electrode, a gate insulating film covering the gate electrode, a first diffusion region spaced apart from one end of the gate electrode, separated therefrom by the gate insulating film and by the spacer element which reduces the electric field between the gate and first diffusion region, the first diffusion region extending vertically above the gate insulating film, and a second diffusion region disposed above the gate insulating film having one end spaced from the first diffusion vertically extending region.
