Plasma etching cdte
WebHgCdTe is one of the dominating materials for infrared detection. To pattern this material, our group has proven the feasibility of SiO2 as a hard mask in dry etching process. In recent years, the SiO2 mask patterned by plasma with an auto-stopping layer of ZnS sandwiched between HgCdTe and SiO2 has been developed by our group. In … WebApr 1, 2010 · CdTe Microwave Etch rate 1. Introduction ECR plasma etching technique is one of the leading techniques in the fabrication of semiconductor devices that leads to anisotropic profiles and damage free surfaces. Wet chemical etching leaves behind an amorphous tellurium layer and residual carbon contamination.
