Abstract
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.
