Abstract

A method and apparatus for performing a dielectric etch, etch mask stripping, and etch chamber clean. A wafer is placed in an etch chamber. A dielectric etch is performed on the wafer using an in situ plasma generated by an in situ plasma device in the etch chamber. The etch mask is stripped using a remote plasma generated in a remote plasma device connected to the etch chamber. The wafer is removed from the etch chamber and either the in situ plasma or the remote plasma may be used to clean the etch chamber. In etch chambers that do not use confinement rings, a heater may be used to heat the etch chamber wall to provide improved cleaning.
