    摘要: A method for forming a metal gate is provided. First, a dummy material is formed to completely cover a substrate. Second, a dopant is selectively implanted into the dummy material. Then, some of the dummy material is removed to expose part of the substrate and to form a dummy gate including a dopant region disposed between a first region and a second region. Later an interlayer dielectric layer is formed to surround the dummy gate. Next, a selective etching step is carried out to remove the first region to form a recess without substantially removing the dopant region. Afterwards, the recess is filled with a material set to form a metal gate.
