WebSilicon Carbide (SiC) is a compound semiconductor material. While there are some types of crystalline structures including 3C-SiC, 6H-SiC and 4H-SiC, it is considered that 4H-SiC is … WebThe effect of water and TMAH concentration on the etching kinetics of poly-Si was investigated by using various concentrations of TMAH solution. It is found that H 2 O in TMAH solution plays an important role in etching poly-Si. Presence of dissolved CO 2 and O 2 in TMAH solution tends to inhibit etching of poly-Si.
