    摘要: A method of manufacturing a semiconductor device having metal gate includes providing a substrate having a first transistor and a second transistor formed thereon, the first transistor having a first gate trench formed therein, forming a first work function metal layer in the first gate trench, forming a sacrificial masking layer in the first gate trench, removing a portion of the sacrificial masking layer to expose a portion of the first work function metal layer, removing the exposed first function metal layer to form a U-shaped work function metal layer in the first gate trench, and removing the sacrificial masking layer. The first transistor includes a first conductivity type and the second transistor includes a second conductivity type. The first conductivity type and the second conductivity type are complementary.

    摘要: An electrical contact includes a substrate, at least an insulation layer, a metal layer, a conductive layer, and a metal silicide layer. The substrate includes at least a silicon region. The insulation layer is disposed on the substrate and includes at least a contact hole exposing the silicon region. The metal layer is formed on the sidewalls and the bottom of the contact hole. The metal layer adjacent to the bottom surface is thinner than the metal layer on the sidewalls. The conductive layer covers the metal layer and fills up the contact hole. The metal silicide layer is adjacent to the bottom of the contact hole.
