Abstract:
A method of forming an O3-TEOS oxide film on a substrate, said method comprising:providing a substrate comprising a base film for which O3-TEOS oxide has base material dependence when deposited directly thereon at a first temperature; depositing a first portion of O3-TEOS oxide on said base film at a second temperature greater than said first temperature and sufficient to prevent the O3-TEOS oxide from exhibiting said base material dependence with the base film; and subsequently depositing a second portion of O3-TEOS oxide directly on the first portion of O3-TEOS oxide film at a temperature substantially less than that at which the first portion of O3-TEOS oxide is formed, whereby the rate at which the second portion of O3-TEOS oxide is deposited is higher than that at which the first portion of O3-TEOS oxide is deposited.
