Abstract:
A vertical resonator type surface light emitting semiconductor laser device having sequentially provided thereon a semiconductor substrate comprising: a first conductivity type semiconductor multi-layered film reflection mirror; an active layer; an oxidized emitting port formed by steam oxidation; a second conductivity type semiconductor multi-layered film reflection mirror; a second conductivity type contact layer; a contact electrode having an opening for emitting laser light; a protective film for protecting said opening; an insulating film; a wiring electrode formed on said insulating film; and an electrode having a conductivity type that is different from said contact electrode,wherein a surface area of said protective film is greater than an area of the opening of the contact electrode and smaller than an area of the contact electrode to prevent damage due to fabrication after forming said contact electrode, and a contact hole is formed in said insulating film so as to include therein the protective film positioned in said opening, a size of said contact hole being smaller than an area of said contact electrode, and said contact hole connecting said wiring electrode and said contact electrode.
