Abstract:
Processing methods may be performed to expose a contact region on a semiconductor substrate. The methods may include selectively recessing a first metal on a semiconductor substrate with respect to an exposed first dielectric material. The methods may include forming a liner over the recessed first metal and the exposed first dielectric material. The methods may include forming a second dielectric material over the liner. The methods may include forming a hard mask over selected regions of the second dielectric material. The methods may also include selectively removing the second dielectric material to expose a portion of the liner overlying the recessed first metal.

Claim (Index 20):
The method of exposing a contact region of  claim 18 , wherein at least one of the first selective removal operation and the second selective removal operation comprises a dry etch using a plasma enhanced fluorine-containing precursor.
