Metal oxide protective layer for a semiconductor device |
摘要 |
Embodiments related to metal oxide protective layers formed on a surface of a halogen-sensitive metal-including layer present on a substrate processed in a semiconductor processing reactor are provided. In one example, a method for forming a metal oxide protective layer is provided. The example method includes forming a metal-including active species on the halogen-sensitive metal-including layer, the metal-including active species being derived from a non-halogenated metal oxide precursor. The example method also includes reacting an oxygen-containing reactant with the metal-including active species to form the metal oxide protective layer. |

1. A method of forming a metal oxide protective layer on a surface of a halogen-sensitive metal-including layer present on a substrate processed in a semiconductor processing reactor, the method comprising:
forming a metal-including active species on the halogen-sensitive metal-including layer, the metal-including active species being derived from a non-halogenated metal oxide precursor, reacting an oxygen-containing reactant with the metal-including active species to form the metal oxide protective layer; and forming a metal-including film comprising material selected from the group consisting of a metal-including dielectric material and a metal-including barrier material and comprising residual halogen atoms on top of the metal oxide protective layer by exposing the metal oxide protective layer to a halogen-including metal compound. |
