    摘要: A nitride semiconductor laser device is formed by growing a group III nitride semiconductor multilayer structure on a substrate containing no Al. The group III nitride semiconductor multilayer structure forms a structure including an n-type semiconductor layer, a p-type semiconductor layer, and a light emitting layer held between the n-type semiconductor layer and the p-type semiconductor layer. The n-type semiconductor layer includes an n-type cladding layer containing Al and an n-type guide layer having a smaller band gap than the n-type cladding layer. The p-type semiconductor layer includes a p-type cladding layer containing Al and a p-type guide layer having a smaller band gap than the p-type cladding layer. A removal region is formed by partially removing the layers containing Al in the group III nitride semiconductor multilayer structure from the substrate.

    摘要: The present invention is to provide a semiconductor laser device manufacturing method for realizing highly reliable semiconductor laser devices. The semiconductor laser device manufacturing method includes: cutting a wafer into bar-shaped wafers by scanning an electron beam on the front side of the wafer on which a semiconductor laser structure has been formed so as to cause cracks which trigger the cutting of the wafer; and depositing front and back coating films on the end faces, which have been newly exposed by the cutting of the wafer, of the cut wafers. In the method the cut wafers are transferred in a non-ambient atmosphere at a time between the cutting of the wafer and the depositing of the end face coating films.
