Abstract
A semiconductor device comprising: a p or p+ doped portion; an n or n+ doped portion separated from the p or p+ doped portion by a semiconductor drift portion; an insulating portion provided adjacent the drift portion and at least one of the doped portions in a region where the drift portion and said at least one doped portion meet; and at least one additional portion which is arranged for significantly reducing the variation of the electric field strength in said region when a voltage difference is applied between the doped portions.
