Abstract:
1. A method of deposition of oxide materials comprising: a. providing a substrate, wherein said substrate has a substrate temperature; b. providing a deposition chamber holding said substrate, wherein said chamber has a chamber pressure and a chamber wall temperature; c. providing a precursor molecule containing an atom of said oxide material to said chamber, wherein said precursor has a precursor line temperature and a precursor source temperature; d. providing an oxidant to said chamber, wherein said oxidant has an oxidant source flow rate; and e. providing water to said chamber, wherein said water has a water source temperature; whereby alternating pulses of said precursor, said water and said oxidant are integrated with purges of said chamber to provide low contamination levels and high growth rates of oxide material on said substrate, whereas said pulses and said purge comprise durations and flow rates.
