Abstract:
A method for via alignment includes forming first airgaps between interconnect structures and depositing a pinch off layer to close off openings to the first airgaps. A protection layer is formed in divots in the pinch off layer. The protection layer and the pinch off layer are planarized to form a surface where the protection layer remains in the divots. An interlevel dielectric layer (ILD) is deposited on the surface. The ILD and the pinch off layer are etched using the protection layer as an etch stop to align a via and expose the interconnect structure through the via.

Claim (Index 17):
The device as recited in  claim 14 , further comprising a trench formed in the ILD in communication with the via and being filled with a conductive material in the via and the trench to form a contact and metal line, respectively.
