Zusammenfassung:The present invention provides for treating a surface of a semiconductor material. The method comprises exposing the surface of the semiconductor material to a halogen etchant in a hydrogen environment at an elevated temperature. The method controls the surface roughness of the semiconductor material. The method also has the unexpected benefit of reducing dislocations in the semiconductor material.
