Abstract
A method is provided for additionally oxidizing a thin-film oxide. The method includes: providing a substrate; depositing an MyOx (M oxide) layer overlying the substrate, where M is a solid element having an oxidation state in a range of +2 to +5; treating the MyOx layer to a high density plasma (HDP) source; and, forming an MyOk layer in response to the HDP source, where k>x. In one aspect, the method further includes decreasing the concentration of oxide charge in response to forming the MyOk layer. In another aspect, the MyOx layer is deposited with an impurity N, and the method further includes creating volatile N oxides in response to forming the MyOk layer. For example, the impurity N may be carbon and the method creates a volatile carbon oxide.
