Abstract
In this paper we have investigated the low pressure chemical vapor deposition (LPCVD) of undoped silicon films from SiH/sub 4/ at low temperatures in the range of 500-550/spl deg/C and the pressure range of 20-100 Pa by means of a variable distance between wafers, ranging from 6 to 60 mm within the same run of an industrial reactor. A simple plug flow model was fitted to the experimental data in order to determine the kinetic constants of the gas phase and surface reactions responsible for the film deposition.
