Patent ID: 8093083

Claim:
A method for manufacturing a semiconductor light emitting device including a crystal layer including a nitride semiconductor, the crystal layer containing In atoms and Ga atoms, the method comprising: forming the crystal layer by supplying a source gas including a first molecule including Ga atoms and a second molecule including In atoms onto a major surface of a base body, the crystal layer having a ratio xs of a number of the In atoms to a total of the number of the In atoms and a number of the Ga atoms being not less than 0.2 and not more than 0.4, a vapor phase supply ratio xv of In being a ratio of a second partial pressure to a total of a first partial pressure and the second partial pressure, the first partial pressure being a pressure of the first molecule and a degradation species of the first molecule on the source gas, the second partial pressure being a pressure of the second molecule and a degradation species of the second source molecule on the source gas, (1−1/xv)/(1−1/xs) being less than 0.1.
