Abstract:
A semiconductor device includes a first field effect transistor (FET) including a first gate dielectric layer and a first gate electrode. The first gate electrode includes a first lower metal layer and a first upper metal layer. The first lower metal layer includes a first underlying metal layer in contact with the first gate dielectric layer and a first bulk metal layer. A bottom of the first upper metal layer is in contact with an upper surface of the first underlying metal layer and an upper surface of the first bulk metal layer.
