Abstract: A GaN device is formed on a semiconductor substrate having a plurality of recessed regions formed in a surface thereof. A seed layer, optional buffer layer, and gallium nitride layer such as a carbon-doped gallium nitride layer are successively deposited within the recessed regions. Improved current collapse response of the GaN device is attributed to maximum length and width dimensions of the multilayer stack.

Abstract: After forming a trench extending through a (100) silicon layer and a buried insulator layer and into a (111) silicon layer of a semiconductor-on-insulator (SOI) substrate, and prior to epitaxial growth of a Group III nitride material from a sub-surface of the (111) silicon layer that is exposed by the trench, a first sidewall spacer including a first dielectric material that can effectively prevent Group III elements from diffusing into silicon of the SOI substrate during the high temperature epitaxial growth of the Group III nitride materials is formed on sidewalls of the trench, following by forming a second sidewall spacer on the first sidewall spacer. The second sidewall spacer includes a second dielectric material that provides better growth selectivity towards the Group III nitride material than the first dielectric material, thus facilitating the growth of the Group III nitride material from the sub-surface of the (111) silicon layer.

Abstract: After forming an opening extending through a (100) silicon layer and a buried insulator layer and into a (111) silicon layer of a semiconductor-on-insulator (SOI) substrate, a light-emitting element is formed within the opening. A portion of the (111) silicon layer located beneath the light-emitting element is patterned to form a patterned structure for tuning light emission characteristics and enhancing efficiency of the light-emitting element. Next, at least one field effect transistor (FET) is formed on the (100) silicon layer for driving the light-emitting element.
