    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.

    摘要: The invention is directed to a method for manufacturing a semiconductor. The method comprises steps of providing a substrate having a gate structure formed thereon and forming a source/drain extension region in the substrate adjacent to the gate structure. A spacer is formed on the sidewall of the gate structure and a source/drain region is formed in the substrate adjacent to the spacer but away from the gate structure. A bevel carbon implantation process is performed to implant a plurality carbon atoms into the substrate and a metal silicide layer is formed on the gate structure and the source/drain region.

A first gate structure and a second gate structure are formed on the first active region and the second active region and a first spacer is formed surrounding the first gate structure and the second gate structure. A source/drain region for the first transistor and the second transistor is formed. The first spacer is removed from the first gate structure and the second gate structure and a cap layer is disposed on the first transistor and the second transistor and the cap layer covering the second transistor is removed thereafter. An etching process is performed to form a recess in the substrate surrounding the second gate structure. An epitaxial layer is formed in the recess and the cap layer is removed from the first transistor.
