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,
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-2or 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.
