Patent ID: 8610289

Claim:
A semiconductor component comprising: a first layer comprising a semiconductor material substrate; a second layer comprising a second material; two intermediate layers disposed between the first and second layers, and comprising the materials of the first and second layers, a first of said intermediate layers facing the second layer, and comprising a eutectic mixture of the materials of the first and second layers; and an electroconductive contact forming an electroconductive connection to the first layer and extending at least from an outer surface of the second layer into the second layer, the electroconductive contact originating from the outer surface of said second layer, and comprising a solderable or wettable metallic material, which is alloyed into the second layer and the first intermediate layer, or which forms a mixture with the material of the second layer and the first intermediate layer, and a connector soldered onto said solderable or wettable material; wherein the solderable or wettable metallic material comprises at least one material selected from the group consisting of Sn, Pb, In, Ga, Cd, Fe, Au, Ti, Hf, Zn, and Mg; and wherein the solderable or wettable metallic material additionally comprises at least one of Ca and Ba.
