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 1):
A structure comprising:\n a first metal line and a second metal line in a first dielectric layer, wherein top surfaces of the first metal line and the second metal line are higher than a top surface of the first dielectric layer; a first liner extending along a top surface of the first metal line, a first sidewall of the first metal line, an adjacent second sidewall of the second metal line, and a top surface of a portion of the first dielectric layer disposed between the first metal line and the second metal line; a second dielectric layer over the first liner, the first metal line, and the second metal line; a void disposed between the first metal line and the second metal line, wherein the void is formed entirely within the second dielectric layer, and wherein a top of the void is lower than top surfaces of the first metal line; and a conductive feature in the second dielectric layer, the conductive feature being electrically connected to the first metal line.
