Abstract:
1. A semiconductor element having reduced dimensions, said semiconductor element comprising: an insulating surface layer in which electric contact connections are provided, the connections being connected to respective first and second contact areas situated beneath the insulating surface layer and spaced from each other along an inwardly-facing surface of the insulating surface layer, wherein at least the first contact area is a first conductive type material and wherein the second contact area is a second conductive type material; a further area formed by two layers of mutually different conductive type materials disposed beneath the insulating surface layer, wherein the further area is positioned between and is spaced from each of the first and second contact areas; wherein an inwardly-facing surface of each of the first and second contact areas and an inwardly-facing surface of the further area include an overlying layer of the second conductive type material, wherein the overlying layer of the second conductive type material has a thickness of about 1 μm or less and has a doping concentration of 10 an inner silicon dioxide insulating layer on a side of the overlying layer distal from the surface layer, the inner silicon dioxide insulating layer being effective with the overlying layer of the second conductive type material having a thickness of about 1 μm or less to thereby provide an increase in doping concentration of the overlying layer of the second conductive type material and provide a reduced size semiconductor element.
