Abstract

In this paper, GaSb-based material in the near-infrared semiconductor laser has a broad application prospects. For the problems and etching solution suitable particularly critical of etching GaSb-based material. we studied on different etchant experimental analysis the HCl+HNO3(30+1)@T=5 ,37% HCl, HNO3+(0.08MHCl+CH3COOH) and HCl+H2O2+H2O(60+1+1), due to etching, the effects of different etching solutions on GaSb surface morphology, corrosion rate, etc., obtained HCl + H2O2 + H2O (60 + 1 + 1) treatment results was better, SEM showed the etched edge relatively tidy, relatively steep side, etched crystal to better selectivity, AFM surface roughness was 1.7nm.
