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 the steps of:
providing a halogen-sensitive metal-including layer present on a substrate; forming a metal oxide protective layer overlying the halogen-sensitive metal-including layer, the metal oxide protective layer derived from a non-halogenated metal oxide precursor; and forming a high-k dielectric metal-including film overlaying the metal oxide protective layer by exposing the metal oxide protective layer to a halogen-including metal compound.
