    摘要: III-N material grown on a silicon substrate includes a single crystal rare earth oxide layer positioned on a silicon substrate. The rare earth oxide is substantially crystal lattice matched to the surface of the silicon substrate. A first layer of III-N material is positioned on the surface of the rare earth oxide layer. An inter-layer of aluminum nitride (AlN) is positioned on the surface of the first layer of III-N material and an additional layer of III-N material is positioned on the surface of the inter-layer of aluminum nitride. The inter-layer of aluminum nitride and the additional layer of III-N material are repeated n-times to reduce or engineer strain in a final III-N layer. A cap layer of AlN is grown on the final III-N layer and a III-N layer of material with one of an LED structure and an HEMT structure is grown on the AlN cap layer.

    摘要: An insulative layer on a semiconductor substrate and a method of fabricating the structure includes the steps of depositing a single crystal layer of rare earth oxide on a semiconductor substrate to provide electrical insulation and thermal management. The rare earth oxide is crystal lattice matched to the substrate. A layer of single crystal IIIOxNy is formed in overlying relationship on the rare earth oxide by transitioning from the layer of rare earth oxide to a single crystal layer of IIIOxNy within a one wafer single epitaxial process. In the preferred embodiment the substrate is silicon, the rare earth oxide is Gd2O3, and the IIIOxNy includes AlOxNy.

    摘要: A method of forming a layer of amorphous silicon oxide positioned between a layer of rare earth oxide and a silicon substrate. The method includes providing a crystalline silicon substrate and depositing a layer of rare earth metal on the silicon substrate in an oxygen deficient ambient at a temperature above approximately 500° C. The rare earth metal forms a layer of rare earth silicide on the substrate. A first layer of rare earth oxide is deposited on the layer of rare earth silicide with a structure and lattice constant substantially similar to the substrate. The structure is annealed in an oxygen ambience to transform the layer of rare earth silicide to a layer of amorphous silicon and an intermediate layer of rare earth oxide between the substrate and the first layer of rare earth oxide.
