Abstract:
1. A process of growing a silicon dioxide thin film on a part in a chamber by a sequential chemical vapor deposition process, which comprises a plurality of deposition cycles, each of the cycles comprising in order: removing gases from the chamber; exposing the part to a first reactant by introducing a first reactant comprising a gaseous silicon compound that does not contain oxygen into the chamber, wherein the first reactant adsorbs on the part, and wherein the first reactant includes the silicon of the thin film to be formed; removing gases from the chamber; exposing the part, coated with the first reactant to atomic hydrogen, wherein the atomic hydrogen reduces the first reactant on the part to silicon; removing gases from the chamber; and exposing the part coated with silicon to oxygen, wherein the oxygen converts the silicon on the part to silicon dioxide.
