Abstract:
The present invention provides a nitride system semiconductor device which decreases cost and improves productivity without heat treatment after the growth and which increases in lifetime and reliability by enhancing the quality of a p-type conductive layer, and a method for manufacturing the nitride system semiconductor device. The nitride system semiconductor device has a multilayer structure of an n-type In.sub.x Ga.sub.y Al.sub.z B.sub.1-x-y-z N.sub.m P.sub.n As.sub.1-m-n (0.ltoreq.x, 0.ltoreq.y, 0.ltoreq.z, 0.ltoreq.x+y+z.ltoreq.1, 0
