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 20):
The process as claimed in  claim 1 , wherein the nitride is gallium nitride.
