    Abstract: High quality epitaxial layers of monocrystalline materials can be grown overlying monocrystalline substrates such as large silicon wafers by forming a compliant substrate for growing the monocrystalline layers. One way to achieve the formation of a compliant substrate includes first growing an accommodating buffer layer on a silicon wafer. The accommodating buffer layer is a layer of monocrystalline oxide spaced apart from the silicon wafer by an amorphous interface layer of silicon oxide. The amorphous interface layer dissipates strain and permits the growth of a high quality monocrystalline oxide accommodating buffer layer. The accommodating buffer layer is lattice matched to both the underlying silicon wafer and the overlying monocrystalline material layer. Any lattice mismatch between the accommodating buffer layer and the underlying silicon substrate is taken care of by the amorphous interface layer. In addition, formation of a compliant substrate may include utilizing surfactant enhanced epitaxy, epitaxial growth of single crystal silicon onto single crystal oxide, and epitaxial growth of Zintl phase materials.

    Abstract: High quality epitaxial layers of monocrystalline materials can be grown overlying large silicon wafers by first growing an accommodating buffer layer (202) on a silicon substrate (200). The accommodating buffer layer (202) is a layer of monocrystalline material spaced apart from the silicon substrate (200) by an amorphous interface layer (204) of silicon oxide. The amorphous interface layer dissipates strain and permits the growth of a high quality monocrystalline accommodating buffer layer. Any lattice mismatch between the accommodating buffer layer and the underlying silicon substrate is taken care of by the amorphous interface layer. Utilizing this technique permits the fabrication of semiconductor structures formed by high quality Group III-V nitride films.

    Abstract: A method of forming a (gallium, aluminum, indium) nitride base layer on a substrate for subsequent fabrication, e.g., by MOCVD or MBE, of a microelectronic device structure thereon. Vapor-phase (Ga, Al, In) chloride is reacted with a vapor-phase nitrogenous compound in the presence of the substrate, to form (Ga, Al, In) nitride. The (Ga, Al, In) nitride base layer is grown on the substrate by HVPE, to yield a microelectronic device base comprising a substrate with the (Ga, Al, In) nitride base layer thereon. The product of such HVPE process comprises a device quality, single crystal crack-free base layer of (Ga, Al, In) N on the substrate, in which the thickness of the base layer may, for example, be on the order of 2 microns and greater and the defect density of the base layer may, for example, be on the order of 1E8 cm.sup.-2 or lower. Microelectronic devices thereby may be formed on the base layer, over a substrate of a foreign (poor lattice match) material, such as sapphire. Devices which may be fabricated utilizing the HVPE base layer of the invention include light emitting diodes, detectors, transistors, and semiconductor lasers.
