发明名称 METHOD FOR PRODUCING GROUP III NITRIDE SEMICONDUCTOR LIGHT-EMITTING DEVICE, GROUP III NITRIDE SEMICONDUCTOR LIGHT-EMITTING DEVICE, AND LAMP
摘要 One object of the present invention is to provide a method for producing a group III nitride semiconductor light-emitting device which has excellent productivity and produce a group III nitride semiconductor light-emitting device and a lamp, a method for producing a group III nitride semiconductor light-emitting device, in which a buffer layer (12) made of a group III nitride is laminated on a substrate (11), an n-type semiconductor layer (14) comprising a base layer (14a), a light-emitting layer (15), and a p-type semiconductor layer (16) are laminated on the buffer layer (12) in this order, comprising: a pretreatment step in which the substrate (11) is treated with plasma; a buffer layer formation step in which the buffer layer (12) having a composition represented by AlxGa1-xN (0&nlE;x<1) is formed on the pretreated substrate (11) by activating with plasma and reacting at least a metal gallium raw material and a gas containing a group V element; and a base layer formation step in which the base layer (14a) is formed on the buffer layer (12).
