Patent ID: 7479448

Claim:
A method of manufacturing a semiconductor light emitting device, comprising: forming a light emitting layer composed of a Group III nitride semiconductors on a substrate by a vapor phase deposition method, by using a doping gas containing an element in Periodic Table Group 6B, and a mixed gas including a Group III precursor gas and a nitrogen source gas, wherein a molar flow rate of the doping gas is made excessive more than a molar flow rate of the Group III precursor gas; wherein the step of forming said light emitting layer is executed after forming Group III nitride semiconductor layers containing an element in Periodic Table Group 4B as an impurity on said substrate by a vapor phase deposition method; and wherein after forming Group III nitride semiconductor layers containing an element in Periodic Table Group 4B as an impurity, a film-forming gas used for forming the Group III nitride semiconductor layers is purged, and next, said light emitting layer is formed.
