The article discusses the possibility of using silicone lacquer as a masking coating when creating micro-dimensional mesa structures on the 4H-SiC surface using the reactive ion-plasma etching method. The etching process was carried out on a setup with an ICP plasma source. The experiments were performed with the aim of determining the dependence of the angle of inclination of the wall of the mesa structure on the parameters of the etching process. The etching results were recorded with a Helius nanolab instrument complex and a Quanta Inspec raster electron microscope.
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.
