    Abstract: The metal gate structure includes at least a substrate, a dielectric layer, first and second trenches, first metal layer and second metal layers, and two cap layers. In particular, the dielectric layer is disposed on the substrate, and the first and second trenches are disposed in the dielectric layer. The width of the first trench is less than the width of the second trench. The first and second metal layers are respectively disposed in the first trench and the second trench, and the height of the first metal layer is less than or equal to the height of the second metal layer. The cap layers are respectively disposed in a top surface of the first metal layer and a top surface of the second metal layer.

    Abstract: A method of forming a semiconductor device having a metal gate includes the following steps. First of all, a first gate trench is formed in a dielectric layer. Next, a first work function layer is formed, covering the first gate trench. Then, a protection layer is formed in the first gate trench, also on the first work function layer. Then, a patterned sacrificial mask layer is formed in the first gate trench to expose a portion of the protection layer. After that, the exposed protection layer is removed, to form a U-shaped protection layer in the first gate trench. As following, a portion of the first work function layer under the exposed protection layer is removed, to form a U-shaped first work function layer in the first gate trench. Finally, the patterned sacrificial mask layer and the U-shaped protection layer are completely removed.
