Abstract:
A method embodiment includes forming a hard mask over a dielectric layer and forming a first metal line and a second metal line extending through the hard mask into the dielectric layer. The method further includes removing the hard mask, wherein removing the hard mask defines an opening between the first metal line and the second metal line. A liner is then formed over the first metal line, the second metal line, and the dielectric layer, wherein the liner covers sidewalls and a bottom surface of the opening.

Claim (Index 17):
A method comprising:\n forming a hard mask over a first dielectric layer; forming a first conductive line and a second conductive line extending through the hard mask into the first dielectric layer; removing the hard mask; forming a first liner over the first conductive line, the second conductive line, and the first dielectric layer, wherein forming the first liner defines an opening between the first liner on adjacent sidewalls of the first conductive line and the second conductive line; forming a second dielectric layer over the first liner, the first conductive line, the second conductive line, and the first dielectric layer, wherein the forming the second dielectric layer seals the opening to define a void between the first conductive line and the second conductive line, a top of the void being lower than a top surface of the first conductive line; and forming a conductive feature in the second dielectric layer, the conductive feature being electrically connected to the first conductive line.
