Abstract
A method for near atmospheric pressure chemical vapor deposition of a silicon based film onto a substrate includes introducing into a deposition chamber at about atmospheric pressure: (i) a substrate; (ii) an iodosilane precursor in the vapor state having at least three iodine atoms bound to silicon; and (iii) at least one reactant gas; and maintaining a deposition temperature within the chamber from about 250° C. to about 650° C. for a period of time sufficient to deposit a silicon based film on the substrate. Silicon based films formed by near atmospheric pressure chemical vapor deposition using an iodosilane precursor in a vapor state and methods for forming silicon-based films using ultraviolet assisted chemical vapor deposition are also included.
