Abstract:In this paper we investigate the influence of different metallic (or metal-based) masking materials and plasma techniques for etching and patterning polycrystalline boron-doped diamond thin films. Lift-off technique was used to prepare various testing mask patterns with dimensions ranging from 1 μm to 15 μm. The results of plasma etching utilizing 100 nm Al and Cu masks are compared. Radio frequency and inductively coupled pure oxygen plasma techniques were used to obtain the fine etched structures. A simple e… Show more
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.
