  • Patent number: 10297454
    Abstract: A method is provided for fabricating a semiconductor device. The method includes providing a base substrate including a dummy gate electrode and an interlayer dielectric layer covering a sidewall of the dummy gate electrode. The method also includes forming a sacrificial layer covering a top surface of the interlayer dielectric layer by using a selective atomic layer deposition process, wherein the sacrificial layer exposes a top surface of the dummy gate electrode. In addition, the method includes forming an opening by using the sacrificial layer as an etch mask to remove the dummy gate electrode, and forming a metal gate electrode on the sacrificial layer and in the opening. Further, the method includes planarizing the metal gate electrode and the sacrificial layer until a top surface of the metal gate electrode is leveled with the top surface of the interlayer dielectric layer.

  • Patent number: 8703545
    Abstract: A semiconductor package is provided with an Aluminum alloy lead-frame without noble metal plated on the Aluminum base lead-frame. Aluminum alloy material with proper alloy composition and ratio for making an aluminum alloy lead-frame is provided. The aluminum alloy lead-frame is electroplated with a first metal electroplating layer, a second electroplating layer and a third electroplating layer in a sequence. The lead-frame electroplated with the first, second and third metal electroplating layers is then used in the fabrication process of a power semiconductor package including chip connecting, wire bonding, and plastic molding. After the molding process, the area of the lead-frame not covered by the molding compound is electroplated with a fourth metal electroplating layer that is not easy to be oxidized when exposing to air.
