Abstract:
A semiconductor component includes a semiconductor substrate having a top surface. An opening extends from the top surface into the semiconductor substrate. The opening includes an interior surface. A first dielectric liner having a first compressive stress is disposed on the interior surface of the opening. A second dielectric liner having a tensile stress is disposed on the first dielectric liner. A third dielectric liner having a second compressive stress disposed on the second dielectric liner. A metal barrier layer is disposed on the third dielectric liner. A conductive material is disposed on the metal barrier layer and fills the opening.
