Abstract:
A process allowing at least one semipolar layer of nitride to be obtained, which layer is obtained from a least one among gallium, indium and aluminum on a top surface of a single-crystal layer based on silicon, wherein the process comprises the following steps: etching, from the top surface of the single-crystal layer, a plurality of parallel grooves comprising at least two opposite inclined facets, at least one of two opposite facets having a crystal orientation; masking the top surface of the single-crystal layer such that the facets having a crystal orientation are not masked; and epitaxial growth of the semipolar layer of nitride from the not masked facets; wherein the etching is carried out on a stack comprising the single-crystal layer and at least one stop layer that is surmounted by the single-crystal layer and wherein the etching etches the single-crystal layer selectively with respect to the stop layer so that the etching stops on contact with the stop layer.

Claim (Index 13):
The process as claimed in  claim 12 , wherein the single-crystal layer has a thickness smaller than or equal to 600 nm and preferably smaller than or equal to 500 nm and preferably smaller than or equal to 300 nm and preferably smaller than or equal to 200 nm.
