Abstract:
A process of growing a thin film of non-semiconductor material on a substrate in a reaction chamber by a sequential chemical vapor deposition process comprising a plurality of cycles, each cycle including, in sequence:exposing the part to a stable gaseous first reactant, including an element of the thin film to be formed, wherein more than one monolayer of at least a portion of the first reactant adsorbs on the part; stopping provision of the gaseous first reactant and removing the gaseous first reactant from the chamber; exposing the part, coated with multiple monolayers of the first reactant, to a gaseous second reactant of radicals, wherein the radicals convert the adsorbed portion of the first reactant on the part to multiple monolayers of either an element or compound, wherein a thin film is formed; and stopping provision of the gaseous second reactant and removing the gaseous second reactant from the chamber.
