Abstract:
A semiconductor device includes a semiconductor substrate, a metal layer, a dielectric layer, and a via. The metal layer is disposed above the semiconductor substrate. The dielectric layer is disposed between the metal layer and the semiconductor substrate. The via is embedded in the dielectric layer and comprises a first portion and a second portion between the first portion and the semiconductor substrate. The first portion of the via has a first width. The second portion of the via has a second width greater than the first width of the first portion.

Claim (Index 17):
A method for manufacturing a semiconductor device, the method comprising:\n forming a first dielectric layer over a source/drain contact; forming a second dielectric layer over the first dielectric layer; forming a third dielectric layer over the second dielectric layer; etching the third dielectric layer to form a first via hole that extends through the third dielectric layer; etching the second dielectric layer to form a second via hole that extends through the second dielectric layer, wherein the second via hole is wider than the first via hole; after etching the second dielectric layer to form the second via hole, etching the first dielectric layer to form a third via hole that exposes the source/drain contact; and filling the first, second, and third via holes with a conductive material.
