Patent ID: 8137460

Claim:
A manufacturing method of a GaN thin film template substrate by a hydride vapor phase epitaxy, wherein the hydride vapor phase epitaxy comprises: spraying HCl (hydrogen chloride) onto Ga (gallium) which is heated and fused in a predetermined temperature to generate GaCl (gallium chloride); and forming a GaN thin film by a reaction of the generated GaCl (gallium chloride) with NH 3 (ammonia) gas on a substrate, the manufacturing method comprising supplying the NH 3 gas at a position which is separated from the substrate by a distance of 0.7-4.0 times as longer than a diameter of the substrate, in an upstream side of the substrate, inside of an atmosphere including the GaCl, through a nozzle, so that a film thickness can be controlled in a nanometer order, wherein a tip of the nozzle through which the NH 3 gas is supplied is located closer to the substrate than a supply port of an N 2 gas supplying pipe from which an N 2 gas is supplied exclusively.
