Abstract:
A method of fabricating a device using a layer with a patterned surface for improving the growth of semiconductor layers, such as group III nitride-based semiconductor layers with a high concentration of aluminum, is provided. The patterned surface can include a substantially flat top surface and a plurality of stress reducing regions, such as openings. The substantially flat top surface can have a root mean square roughness less than approximately 0.5 nanometers, and the stress reducing regions can have a characteristic size between approximately 0.1 microns and approximately five microns and a depth of at least 0.2 microns. A layer of group-III nitride material can be grown on the first layer and have a thickness at least twice the characteristic size of the stress reducing regions. A device including one or more of these features also is provided.

Claim (Index 9):
The device of  claim 1 , wherein the device is configured to be operated as a light emitting device, and wherein at least one of: the characteristic size of the plurality of periodically spaced openings, the depth of the plurality of periodically spaced openings, or the distance between the plurality of periodically spaced openings is less than a wavelength of the radiation emitted during operation of the light emitting device.
