A substrate having at least two metal oxide semiconductor devices of a same conductive type and a gap formed between the two devices is provided. A first stress layer is formed over the substrate to cover the metal-oxide semiconductor devices and the substrate, filling the gap. An etching back process is then performed to remove a portion of the stress material layer inside the gap. A second stress layer and a dielectric layer are sequentially formed on the first stress layer. The first stress layer and the second stress layer provide a same type of stress. A portion of the second stress layer is removed to form a contact opening. A second conductive layer is filled into the contact opening to form a contact.

A method and an apparatus for fabricating a high tensile stress film includes providing a substrate, forming a poly stressor on the substrate, and performing an ultra violet rapid thermal process (UVRTP) for curing the poly stressor and adjusting its tensile stress status, thus the poly stressor serves as a high tensile stress film. Due to a combination of energy from photons and heat, the tensile stress status of the high tensile stress film is adjusted in a relatively shorter process period or under a relatively lower temperature.

A method of manufacturing a metal-oxide-semiconductor (MOS) transistor device is disclosed. A semiconductor substrate and a gate structure positioned on the semiconductor substrate are prepared first. A source region and a drain region are included in the semiconductor substrate on two opposite sides of the gate structure. Subsequently, a stressed cap layer is formed on the semiconductor substrate, and covers the gate structure, the source region and the drain region. Next, an inert gas treatment is performed to change a stress value of the stressed cap layer. Because the stress value of the stressed cap layer can be adjusted easily by means of the present invention, one stressed cap layer can be applied to both the N-type MOS transistor and the P-type MOS transistor.
