Patent ID: 8338273

Claim:
A method of growing a non-polar group III nitride layer on a base layer, the method comprising: masking the base layer with a first dielectric layer, wherein the first dielectric layer is located on select areas of the base layer such that a portion of the base layer is exposed; growing a mushroom-shaped PLOG group III nitride layer via pulse lateral overgrowth epitaxy on the portion of the base layer that is exposed, wherein the PLOG group III nitride layer grows over a portion of the first dielectric layer; masking the mushroom-shaped PLOG group III nitride layer with a second dielectric layer, wherein each side of the mushroom-shaped PLOG group III nitride layer remains exposed; and growing a nonpolar group III nitride layer from each exposed side of the mushroom-shaped PLOG group III nitride layer, wherein the nonpolar group III nitride layer is grown by pulsing a nitrogen source and a group III metal source.
