    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: An adjusting method of channel stress includes the following steps. A substrate is provided. A metal-oxide-semiconductor field-effect transistor is formed on the substrate. The MOSFET includes a source/drain region, a channel, a gate, a gate dielectric layer and a spacer. A dielectric layer is formed on the substrate and covers the metal-oxide-semiconductor field-effect transistor. A flattening process is applied onto the dielectric layer. The remaining dielectric layer is removed to expose the source/drain region. A non-conformal high stress dielectric layer is formed on the substrate having the exposed source/drain region.
