Abstract:SUMMARYThe reaction coefficients of radicals on the growing surface of hydrogenated amorphous silicon nitride (aSiN:H) were studied by applying Monte Carlo simulation. These a-SiN:H films were deposited on trench-patterned silicon wafers using two kinds of gas mixture, SiH 4 -NH 3 and SiH 4 -N 2 , and then measured for their film thickness profiles and composition on the trench wall. The derived total loss coefficient, β, of radicals was estimated from comparison between the experimental results and the simula… 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.
