Claim Text:
1. A method for manufacturing a semiconductor light emitting device, comprising: forming a light emitting layer including a nitride semiconductor on an n-type semiconductor layer including a nitride semiconductor; forming a first film of Al forming a second film including a nitride semiconductor including Mg on the first film; and forming a third film including a nitride semiconductor including Mg on the second film, the forming of the first film including alternately and multiply repeating: a maximum value of a concentration of Mg in a p-side region including the light emitting layer, the first film, and the second film being not less than 1×10 an Al concentration in the p-side region having a maximum value at a first position, the Al concentration being 1/100 of the maximum value at a second position arranged with the first position along a first direction from the light emitting layer toward the first film in a region between the first position and a position corresponding to the light emitting layer, a Mg concentration at the second position being not less than 2×10
