Abstract
The wet oxidation kinetics of AlAs layers of interest in vertical cavi ty surface emitting laser (VCSEL) fabrication are investigated in deta il. The process is modeled as a diffusion-reaction process. For oxidat ion over a long time interval, variation of the oxidation rate with th e variation of the radius of the etched mesa of the VCSEL is observed. A theory has been developed to obtain the rate equation of the oxidat ion process and the dependence of the oxidation rate on the size of th e VCSEL is explained.
