Abstract:
1. A method of fabricating a gallium nitride-based compound semiconductor light-emitting device, including forming a gallium nitride-based compound semiconductor layer whose principal surface is a non-polar plane or a semi-polar plane by metalorganic chemical vapor deposition, where parameters that define growth conditions of the metalorganic chemical vapor deposition include a pressure, a growth rate, a growth temperature, and an In supply mole fraction that is a mole fraction of an In source gas contained in a supplied Group III source gas, a curve that represents a relationship between the growth temperature and the In supply mole fraction for formation of an In x Ga 1-x N (0<x<1) layer of an identical emission wavelength in a case where the pressure and the growth rate are constant having a saturation point which exists between a region where the growth temperature monotonically increases according to an increase of the In supply mole fraction and a region where the growth temperature saturates, the method comprising the steps of: (A) determining the saturation point on the curve; (A2) determining a growth condition which corresponds to the saturation point determined in step (A); and (B) growing an In
