Patent ID: 10998697

Abstract:
A method of manufacturing a surface emitting laser includes: preparing a substrate on which a lower reflector layer, an active layer and an upper reflector layer are formed in this order from the bottom, each of the lower reflector layer and the upper reflector layer including a semiconductor multilayer film; forming an insulating film on the upper reflector layer; cleaning the substrate using isopropyl alcohol after the forming; patterning a photoresist by applying the photoresist on the insulating film and exposing the photoresist, after the cleaning; and forming a high resistance region by implanting ions into portions of the lower reflector layer, the active layer and the upper reflector layer exposed from the photoresist, after the patterning; wherein the cleaning includes cleaning the substrate with a liquid of the isopropyl alcohol and drying the substrate in a vapor of the isopropyl alcohol.
