Abstract
The effect of phosphine/monosilane flow ratio value gamma in the range of 0-0.02 on the apparent activation energy E(a) for an in situ phosp horus-doped polysilicon deposition process has been investigated. A st rong dependence of E(a) on the gamma value has been found. The margina l value of gamma has been determined whereby the apparent activation e nergy is ''saturated'' and becomes practically independent on the phos phine/monosilane flow ratio. An explanation of the obtained results on the basis of two reaction paths existing for the phosphorus-doped pol ysilicon deposition process in the phosphine/monosilane system has bee n proposed.
