Abstract: A method for producing a low-impedance contact between a metallizing layer and a semiconductor material of a first conductivity type having a semiconductor surface, an insulation layer on the semiconductor surface and a semiconductor layer on the insulation layer, includes applying a first insulating layer with a predetermined content of dopants on the semiconductor layer, and structuring the first insulating layer by anisotropic etching, forming first and second openings. The semiconductor layer is anisotropically etched by using the first insulating layer as a mask. A first dopant of a second conductivity type is implanted and driven through the first opening into the semiconductor material with a first phototechnique, forming a first zone in the semiconductor material. A second dopant of the first conductivity type is implanted through the second opening into the semiconductor material with a second phototechnique. A second doped insulating layer is applied over the entire surface.
