摘要: An optical absorption layer comprised of a substance having band gap energy smaller than that GaN is formed on an implanted region in pGaN as ground layer. There performed annealing step from upper surface substrate with predetermined light such infrared light, red or the like, which has The coefficient larger Accordingly, it possible to selectively perform heat treatment directly under vicinity thereof (the region).
