ABSTRACT:
Semiconductor light emitting device and methods for its manufacture comprises a plurality of textured district defined on the surface of the substrate. The initial inclined layer deposition serves to guide the extended defects to designated gettering centers in the trench region where the defects combine with each other. As a result, the defect density in the upper section of the structure is much reduced. By incorporating a blocking mask in the structure, the free propagation of extended defects into the active layer is further restricted. The present invention is useful in the fabrication of semiconductor light emitting devices in misfit systems.
