Patent ID: 7182811

Claim:
A method for producing a semiconductor light emitting device, the method comprising the steps of: growing a nitride semiconductor material on a substrate to form an n-type layer; forming a multiple quantum well structure active layer including a plurality of well layers each made of In x Ga (1-x-y) Al y N (0≦x, 0≦y, x+y<1) and a plurality of barrier layers each made of In a Ga (1-s-t) Al t N (0≦s, 0≦t, s+t<1), the multiple quantum well structure active layer being provided on the n-type layer; and growing a nitride semiconductor material on the multiple quantum well structure active layer to form a p-type layer, wherein the step of growing the p-type layer includes the step of growing a nitride semiconductor material in an atmosphere not containing hydrogen gas while keeping a temperature of the substrate at a first growth temperature.
