Abstract:
1. A method for producing a surface emitting semiconductor device, comprising: a step of forming a semiconductor stacked structure including an active layer, a first semiconductor layer containing aluminum and provided on the active layer, and a distributed Bragg reflector (DBR) portion provided on the first semiconductor layer, the DBR portion including second semiconductor layers and third semiconductor layers alternately stacked to each other, the second semiconductor layers and the third semiconductor layers having different aluminum contents; a step of forming a mesa portion by etching the DBR portion and the first semiconductor layer; an oxidation step of oxidizing the first semiconductor layer from a side face of the mesa portion toward the inside of the mesa portion, and forming an annular oxidized region inside the first semiconductor layer; a first etching step of selectively etching an oxidized region formed in the DBR portion in the oxidation step by a wet etching; and a second etching step of removing a peripheral portion of the DBR portion by etching.
