Abstract:
1. A method for producing a group III nitride semiconductor light-emitting device comprising: an intermediate layer formation step in which an intermediate layer containing group III nitride is formed on a substrate by sputtering, and a laminate semiconductor formation step in which an n-type semiconductor layer having a base layer, a light-emitting layer, and a p-type semiconductor layer are laminated on the intermediate layer in this order, wherein the method includes a pretreatment step in which the intermediate layer is treated using plasma between the intermediate layer formation step and the laminate semiconductor formation step, and a formation step for the base layer which is included in the laminate semiconductor formation step is a step for laminating the base layer by sputtering, and wherein the intermediate layer formation step is carried out in a first chamber, the formation step for the base layer is carried out in a second chamber, and the substrate on which the intermediate layer is formed is taken out from the first chamber between the intermediate layer formation step and the pretreatment step.
