Synthesis of SiOC(-H) films outside generation regions using afterglow plasma under atmospheric pressure have been gaining attention because it allows deposition to complex configuration substrates with large area. We synthesized SiOC(-H) films at different oxygen gas flow rates and substrate temperatures by the atmospheric pressure plasma enhanced chemical vapor deposition method from TrMS/O2/He gases. Substrates were placed at a working distance of 10 mm between discharge electrode and substrate surface. Plasma emission is gradually weakened with an increase in oxygen gas flow rate, and excessive introduction of oxygen into the process caused the plasma to disappear. The SiOC(-H) films were composed of a number of particles; Their large size particles lead to an increasing deposition rate and the non-dense structure of the films. As the oxygen gas flow rate increased, the particle size was larger at 100 nm and related -OH peaks strongly observed. Carbon content of SiOC(-H) films decreased from 17% to only 1.8% with an increase in substrate temperature at 140• C. In this paper, we report the characterization of SiOC(-H) films synthesized under atmospheric pressure PECVD method.
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.
