    摘要: A method of fabricating a rare earth oxide buffered III-N on silicon wafer including providing a crystalline silicon substrate, depositing a rare earth oxide structure on the silicon substrate including one or more layers of single crystal rare earth oxide, and depositing a layer of single crystal III-N material on the rare earth oxide structure so as to form an interface between the rare earth oxide structure and the layer of single crystal III-N material. The layer of single crystal III-N material produces a tensile stress at the interface and the rare earth oxide structure has a compressive stress at the interface dependent upon a thickness of the rare earth oxide structure. The rare earth oxide structure is grown with a thickness sufficient to provide a compressive stress offsetting at least a portion of the tensile stress at the interface to substantially reduce bowing in the wafer.

    摘要: A III-N template formed on a silicon substrate includes a Distributed Bragg Reflector positioned on the silicon substrate. The Distributed Bragg Reflector is substantially crystal lattice matched to the surface of the silicon substrate. An aluminum oxide layer is positioned on the surface of the Distributed Bragg Reflector and substantially crystal lattice matched to the surface of the Distributed Bragg Reflector. A layer of aluminum nitride (AlN) is positioned on the surface of the aluminum oxide layer and substantially crystal lattice matched to the surface of the aluminum oxide layer. A III-N LED structure including at least one III-N layer can then be grown on the aluminum nitride layer and substantially crystal lattice matched to the surface of the aluminum nitride layer.

    摘要: III-N material grown on a silicon substrate includes a single crystal buffer positioned on a silicon substrate. The buffer is substantially crystal lattice matched to the surface of the silicon substrate and includes aluminum oxynitride adjacent the substrate and aluminum nitride adjacent the upper surface. A first layer of III-N material is positioned on the upper surface of the buffer. An inter-layer of aluminum nitride (AlN) is positioned on the first III-N layer and an additional layer of III-N material is positioned on the inter-layer. 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.
