Amorphous silicon carbide thin films (SiC) were produced by PECVD technique at room temperature. Post-annealing was used to crystallize the SiC films. These films were etched in reactive ion etching system using SF6 + O2 gas mixtures. The influence of O2 concentration in process was investigated by mass spectrometry technique. Using this technique, it was possible to estimate the better conditions where the etching rates are optimal and also to verify the contributions of etchant species like F and O on the production of the main volatile products SiF4, CO and CO2.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
