FABRICATION OF GROOVED SEMICONDUCTOR DEVICES

摘要

THE FABRICATION OF GROOVED SEMICONDUCTOR DEVICES V-grooves are etched in Group III-V compound semiconductors using a composite mask comprising a thin native oxide layer on the semiconductor and a dielectric etch mask on the native oxide. Described in detail is the application of this technique to etching V-grooves in InP for the fabrication of CSBH InP/InGaAsP lasers.
