    摘要: The invention uses implantation, typically hydrogen implantation or implantation of hydrogen in combination with other elements, to a selected depth into a wafer with that contains one or more etch stops layers, treatment to split the wafer at this selected depth, and subsequent etching procedures to expose etch stop layer and ultra-thin material layer. A method for making an ultra-thin material layer bonded to a substrate, has the steps: (a) growing an etch stop layer on a first substrate; (b) growing an ultra-thin material layer on the etch stop layer; (c) implanting an implant gas to a selected depth into the first substrate; (d) bonding the ultra-thin material layer to a second substrate; (e) treating the first substrate to cause the first substrate to split at the selected depth; (f) etching remaining portion of first substrate to expose the etch stop layer, and (g) etching the etch stop layer to expose the ultra-thin material layer.

    摘要: Semiconductor devices that include a semiconductor structure integrated with one or more diamond material layers. A first diamond material layer is formed on a bottom surface and optionally, the side surfaces of the semiconductor structure. In some embodiments, at least a portion of the semiconductor structure is embedded in the diamond. An electrical device can be formed on a top surface of the semiconductor structure. A second diamond material layer can be formed on the top surface of the semiconductor structure. The semiconductor structure can include a III-nitride material such as GaN, which can be embedded within a the first diamond material layer or encased by the first and/or second diamond material layer.
