Patent ID: 7208337

Claim:
A method for producing a light-emitting semiconductor component, comprising the steps of: (a) epitaxially depositing a light-emitting semiconductor layer ( 2 ) on a growth substrate ( 1 ), (b) providing the semiconductor layer ( 2 ) with a metallic contact layer ( 3 ), (c) producing an adhesion and wetting layer ( 6 ) at least above the metallic contact layer ( 3 ), (d) applying, producing or depositing a mechanically stable carrier substrate ( 7 ) onto the adhesion and wetting layer ( 6 ), (e) separating the semiconductor layer ( 2 ) from the growth substrate ( 1 ), (f) etching of mesa trenches ( 10 ) for the definition of individual chips between the mesa trenches ( 10 ), the mesa trenches ( 10 ) at least extending through the entire semiconductor layer ( 2 ) and the entire contact layer ( 3 ), (g) applying an electrical contact ( 8 ) on the semiconductor layer ( 2 ), and (h) singulating the chips by separation along the mesa trenches ( 10 ).
