Title: Method of manufacturing surface emitting semiconductor laser
Inventor: FURUSAWA KOTARO
IPC: H01S5/00
Filed: 1989-12-05
Abstract: PURPOSE:To make it possible to form a very small section to be buried which has a small dependence upon crystal azimuth performance and remove etching mask completely by using a laminated layer body of an SiO2 film and a resist layer as a mask, and then carrying out chemical etching for GaAlAs and the SiO2 film. CONSTITUTION:A buffer layer 2, a first clad layer 3, an activity layer 4, a second clad layer 5, a cap layer 6, and a first mask layer 7 are formed continuously on a substrate 1. On the mask layer 7 there are formed an SiO2 film 8 and further a resist layer 9. The SiO2 film 8 excepting the area where the resist layer 9 is formed is removed by etching with an etchant for SiO2. Then, a lamination layer body of the SiO2 film 8 and the resist layer 9, which is used as a mask, is etched up to a section directly over the first clad layer 3 so that a round-shaped mesa section may be formed. Then, the first mask layer 7 is side-etched with a GaAlAs etchant and a non-reactive section 8a of the SiO2 film 8 is exposed. After that process is over, the SiO2 film 8 is etched and removed with the etchant for SiO2. During this operation, both the resist layer 9 and a reactant 10 are removed.
