  • Publication number: 20220098735
    Abstract: Disclosed herein are methods for the deposition of a plasma resistant coating onto a substrate using an atomic layer deposition process. The process includes carrying out a an ALD deposition cycle that includes at least the steps of: providing an ALD reactant chamber with a substrate; pulsing into the chamber a first coating precursor (Coat1Pre); pulsing into the chamber a second coating precursor (Coat2Pre), substantially immediately after the completion of the pulse of Coat1Pre; purging the chamber; pulsing into the chamber a co-reactant precursor; and purging the chamber. At completion of a cycle, a monolayer is deposited. The monolayer is or is included in a mixed coating of substantial homogeneity. The methods may be varied, e.g., the second or third steps can be repeated multiple times (1 to 4 times or 2 to 8 times). If one desired to prepare mixed coatings or more than two components, other steps may be added, e.g.
