Abstract:
A semiconductor substrate structure and process for fabrication of the semiconductor substrate structure are described. The semiconductor substrate structure includes a silicon carbide (SiC) wafer substrate, an active gallium nitride (GaN) layer and a layer of microcrystalline diamond (MCD) layer disposed between the SiC wafer substrate and the GaN active layer. The MCD) layer is bonded to the SiC wafer substrate and to the GaN active layer.

Claim (Index 2):
The process of  claim 1 , wherein the fabricating of the first intermediate structure comprises:\n providing a first Si host wafer substrate; growing the MCD layer on the first Si host wafer substrate, the first MCD surface and the second MCD surface of the MCD layer having surface topographical irregularities; polishing the first MCD surface to decrease the surface topographical irregularities up to a predetermined first degree of smoothness; forming the first bonding material layer on the first MCD surface, a surface of the bonding material layer having a predetermined second degree of smoothness smoother than the first degree of smoothness; providing the SiC wafer substrate; bonding the SiC wafer substrate to the MCD layer via the first bonding material layer; removing the first Si host wafer substrate; polishing the second MCD surface to decrease the surface topographical irregularities up to the predetermined first degree of smoothness; forming a second bonding material layer on the second MCD surface, the surface of the second bonding material layer having the predetermined second degree of smoothness smoother than the first degree of smoothness.
