Abstract:
An etching process is provided that includes a pre-clean process to remove a surface oxide of a dielectric material. The removal of the oxide can be executed through a thermal reaction and/or plasma process before the etch process. In some embodiments, the removal of the oxide increases etch process control and reproducibility and can improve the selectivity versus oxides.
