COMSOL Multiphysics in Modeling MOCVDs

Y. Shimogaki
Shimogaki Laboratory
Department of Materials Engineering,
The University of Tokyo
Japan

This paper showed that: * SAG-MOCVD is a powerful tool to fabricate OEICs and is also effective to extract true surface kinetics during MOCVD. * GaAs-MOCVD process was examined by SAG analysis where it was seen that below 600ºC, surface kinetics shows non-linear behavior. * Surface ...
