Abstract:
Semiconductor device is provided. The semiconductor device includes a base substrate including a first device region, a second device region, and a transition region separating the first region from the second region. A first work function layer is formed on the base substrate in the second region. A second work function layer is formed on the base substrate in the first region and the transition region, and on the first work function layer in the second region.
