Patent ID: 7329587

Claim:
A method for producing a plurality of semiconductor chips, particularly radiation-emitting semiconductor chips, each having at least one epitaxially produced functional semiconductor layer stack, comprising the following method steps: preparing a growth substrate wafer substantially comprised of semiconductor material from a semiconductor material system that is in terms of lattice parameters the same as or similar to that on which a semiconductor layer sequence for the functional semiconductor layer stack is based, forming in said growth substrate wafer a separation zone disposed parallel to a main face of said growth substrate wafer, joining said growth substrate wafer to an auxiliary carrier wafer, detaching along said separation zone a portion of said growth substrate wafer that faces away from said auxiliary carrier wafer as viewed from said separation zone, forming on the portion of said growth substrate wafer remaining on said auxiliary carrier wafer a growth surface for subsequent epitaxial growth of a semiconductor layer sequence, epitaxially growing said semiconductor layer sequence on said growth surface, applying a chip substrate wafer to said semiconductor layer sequence, detaching said auxiliary carrier wafer, and singulating the composite composed of said semiconductor layer sequence and said chip substrate wafer into mutually separate semiconductor chips.
