Abstract:
A semiconductor device structure comprising: a layer of single crystal compound semiconductor material; and a layer of polycrystalline CVD diamond material, wherein the layer of polycrystalline CVD diamond material is bonded to the layer of single crystal compound semiconductor material via a bonding layer having a thickness of less than 25 nm and a thickness variation of no more than 15 nm, wherein an effective thermal boundary resistance (TBR eff ) as measured by transient thermoreflectance at an interface between the layer of single crystal compound semiconductor material and the layer of polycrystalline CVD diamond material is less than 25 m 2  K/GW with a variation of no more than 12 m 2  K/GW as measured across the semiconductor device structure, and wherein the layer of single crystal compound semiconductor material has one or both of the following characteristics: a charge mobility of at least 1200 cm 2  V −1  s −1 ; and a sheet resistance of no more than 700 Ω/square.

Claim (Index 6):
A method according to  claim 1 , wherein the step of growing the layer of polycrystalline CVD diamond comprises introducing carbon containing gas into the CVD synthesis atmosphere during an initial stages of diamond growth such that the bonding layer is entirely coated in polycrystalline CVD diamond prior to any regions of the bonding layer being etched through to the single crystal compound semiconductor layer.
