Abstract:
An interconnect structure for an integrated circuit, such as a three dimensional integrated circuit (3DIC), and a method of forming the same is provided. An example interconnect structure includes a substrate, a through via extending through the substrate, and a liner disposed between the substrate and the through via. The substrate includes a tapered profile portion. The tapered profile portion abuts the liner.

Claim (Index 1):
An interconnect structure comprising:\n a substrate having a first portion with a tapered surface and a second portion with a planar surface, an apex of the first portion being disposed a first height from the planar surface of the second portion, the first portion having a first width; a conductive via extending through the first portion of the substrate; a liner disposed between the conductive via and the substrate, the tapered surface of the substrate adjoining a sidewall of the liner; a dielectric capping layer disposed on the substrate and adjoining the sidewall of the liner, surfaces of the dielectric capping layer, the liner, and the conductive via being level; and a redistribution layer on the surfaces of the dielectric capping layer, the liner, and the conductive via, the redistribution layer being disposed a second height from the planar surface of the substrate, the second height being greater than the first height, the outermost extent of the redistribution layer being disposed a second width from the sidewall of the liner, the second width being greater than the first width.
