Abstract:
One or more embodiments of techniques or systems for forming a semiconductor structure are provided herein. A first metal region is formed within a first dielectric region. A cap region is formed on the first metal region. A second dielectric region is formed above the cap region and the first dielectric region. A trench opening is formed within the second dielectric region. A via opening is formed through the second dielectric region, the cap region, and within some of the first metal region by over etching. A barrier region is formed within the trench opening and the via opening. A via plug is formed within the via opening and a second metal region is formed within the trench opening. The via plug electrically connects the first metal region to the second metal region and has a tapered profile.

Claim (Index 11):
A semiconductor structure, comprising:\n a first dielectric layer; a first conductive feature disposed within at least some of the first dielectric layer; a cap feature disposed on the first conductive feature and having a top surface that is substantially coplanar with a top surface of the first dielectric layer; a second dielectric layer disposed on the first dielectric layer and on the cap feature; a second conductive feature disposed within the second dielectric layer; and a via extending from the second conductive feature and into the first conductive feature, wherein the via includes:\n a first portion of substantially uniform width extending through the second dielectric layer and the cap feature and into the first conductive feature; and \n a second portion that extends from the first portion within the first conductive feature and has a width that tapers.
