    摘要: A method for fabricating a metal gate includes the following steps. First, a substrate having an interfacial dielectric layer above the substrate is provided. Then, a gate trench having a barrier layer is formed in the interfacial dielectric layer. A source layer is disposed above the barrier layer. Next, a process is performed to have at least one element in the source layer move into the barrier layer. Finally, the barrier layer is removed and a metal layer fills up the gate trench.

    摘要: A method for fabricating a metal-oxide-semiconductor field-effect transistor includes the following steps. Firstly, a substrate is provided. A gate structure, a first spacer, a second spacer and a source/drain structure are formed over the substrate. The second spacer includes an inner layer and an outer layer. Then, a thinning process is performed to reduce the thickness of the second spacer, thereby retaining the inner layer of the second spacer. After a stress film is formed on the inner layer of the second spacer and the source/drain structure, an annealing process is performed. Afterwards, the stress film is removed.
