Patent ID: 7435605

Claim:
A method for fabricating a component having an electrical contact region which includes at least the following steps: providing an epitaxially grown semiconductor layer sequence which comprises an n-conducting AlGaInP-based or AlGaInAs-based outer layer and an active zone which emits electromagnetic radiation, wherein said AlGaInP-based material comprises Al x Ga y In 1-x-y P and wherein said AlGaInAs-based material comprises Al x Ga y In 1-x-y As, where 0<x<1, 0<y<1 and x+y<1; applying an electrical contact material, which includes Au and at least one dopant, directly to the outer layer, the dopant containing at least one element selected from the group consisting of Ge, Si, Sn and Te; and annealing said outer layer.
