Abstract:
As etching processes become more aggressive, increased etch resistivity of the hard mask is desirable. Methods of modulating the etch rate of the mask and optionally the underlying material are disclosed. An etch rate modifying species is implanted into the hard mask after the mask etching process is completed. This etch rate modifying species increases the difference between the etch rate of the mask and the etch rate of the underlying material to help preserve the integrity of the mask during a subsequent etching process. In some embodiments, the etch rate of the mask is decreased by the etch rate modifying species. In certain embodiments, the etch rate of the underlying material is increased by the etch rate modifying species.

Claim (Index 7):
The method of  claim 4 , wherein the second etch rate modifying species decreases an etch rate of the epitaxial silicon layer.
