    • A base substrate for gallium nitride wafer and fabricating method for gallium nitride wafer is provided to prevent bend of the nitride gallium film due to the mechanical separation by forming the double layer structure of nitride and oxide on the base substrate. In a base substrate for gallium nitride wafer and fabricating method, a base substrate having the double layer of the nitride thin film layer and acid solubility chemical etch layer are prepared(S1). A nitride gallium film is grown up on the nitride thin film of the base substrate(S4). The chemical etch layer is etched and the base substrate and nitride gallium film are separated(S5). The nitride gallium film is grown up over 50% of the base substrate thickness. The chemical etch layer comprises selected one of the tiO2, znO, mgO, snO2, srO2, CF4, scAlMgO4, srTiO3, laAlO3, liNbO3, srRuO3, mgAl2O4 and their solid solution.

    • A gallium nitride substrate is provided to reduce cracks capable of being generated in mechanical machining of a substrate by adjusting the size of a hillock formed on the surface of a gallium nitride substrate. A buffer layer(120) is formed on a base substrate(110). A gallium source and a nitrogen source are supplied to a growth furnace until the volume ratio(V/III group ratio) of the nitrogen source to the gallium source becomes a first volume ratio so that a gallium nitride layer(130) with a predetermined thickness is grown on the buffer layer. A gallium source and a nitrogen source are supplied to the growth furnace until the volume ratio of the nitrogen source to the gallium source becomes a second volume ratio higher than the first volume ratio so that a surface layer is formed on the gallium nitride layer. The process for forming the buffer layer can include the following steps. Ammonia gas is supplied to the growth furnace. Mixture gas of ammonia and hydrogen chloride is supplied to the growth furnace. Ammonia gas is supplied to the growth furnace.
