Chemical Vapor Deposition of Silicon from Disilane under Reduced Pressure in a Circular Impinging Jet Reactor: Simulation and Experiments

Abstract: 9 The chemical vapor deposition of silicon from disilane under reduced pressure in an impinging jet reactor has been studied experimentally and simulated numerically by a 2D model. The measured deposition rate and profile have been compared to the results of the calculations performed with various hypotheses concerning both gas-phase and surface reactions. The influence of the number of species considered, of the kinetic rate constants, and of the models used for the reactive sticking coefficient of silane and… Show more

“…All these species can contribute to silicon deposition. But the sticking coefficient of all unsaturated species is known to be equal to one whereas that of saturated molecules is at least several orders lower [18][19][20]. It is then likely that these various silicon precursors contribute differently to nucleation and growth phenomena during the first stages of Si film formation on SiO 2 substrates.…”

“…However, from the studies of Buss et al [47] and Wang et al [48], the sticking coefficient SiH 4 of silane depends on its incident flux F SiH 4 , which is not compliant with a reaction order of 1.…”

“…All these species can contribute to silicon deposition. However, the sticking coefficient of all unsaturated species is most often assumed to be equal to one, whereas that of saturated molecules is at least several orders lower [15][16][17]. Thus, it is likely that these various silicon precursors contribute to both nucleation and growth phenomena differently during the first stages of Si film formation on SiO 2 substrates.…”
