A. Dollet et al., ANALYSIS AND NUMERICAL MODELING OF SILICON-NITRIDE DEPOSITION IN A PLASMA-ENHANCED CHEMICAL-VAPOR-DEPOSITION REACTOR .1. BIDIMENSIONAL MODELING, Plasma sources science & technology, 4(1), 1995, pp. 94-106
A numerical model of silicon nitride deposition from an NH3-SiH4 mixtu
re in a large-sized radiofrequency plasma reactor has been developed.
A bidimensional treatment of transport phenomena, of major importance
in this type of reactor, was used. Analysis of the modelling results s
howed that aminosilane radicals were the main deposition precursors. T
he steep decrease in deposition rate in the flow direction that was ob
served can be explained by examining the calculated concentration prof
iles.
