Abstract:
1. A method for fabricating a Group III nitride compound semiconductor on a substrate through epitaxial growth, said method comprising: forming a mask material, on which a group III nitride compound semiconductor does not epitaxially grow, in a grid pattern on a surface of said substrate; zoning said substrate surface into each device formation region to be exposed; forming a consumption region for a group III nitride compound semiconductor in which said substrate is exposed at each central portion of a band of said mask material formed in said grid pattern; forming a first single crystal group III nitride compound semiconductor by epitaxial growth on each of the exposed and zoned substrate surface as said device formation region; and forming a second single crystal group III nitride compound semiconductor by epitaxial growth in said consumption region, wherein said consumption region is formed by exposing a portion of the surface of said substrate which is not used to form a device.
