The first transistor element comprises at least one first amorphous region and the second transistor element comprises at least one second amorphous region. A stress-creating layer is formed over the first transistor element. The stress-creating layer does not cover the second transistor element. A first annealing process is performed. The first annealing process is adapted to re-crystallize the first amorphous region and the second amorphous region. After the first annealing process, a second annealing process is performed. The stress-creating layer remains on the semiconductor substrate during the second annealing process.

    Abstract: A semiconductor fabrication process includes forming isolation structures (106) on either side of a transistor region, forming a gate structure (110) overlying the transistor region, removing source/drain regions (107) to form source/drain recesses (120), removing portions of the isolation structures to form recessed isolation structures (126), and filling the source/drain recesses with a source/drain stressor such as an epitaxially formed semiconductor. A lower surface of the source/drain recess is preferably deeper than an upper surface of the recessed isolation structure by approximately 10 to 30 nm. Filling the source/drain recesses may precede or follow forming the recessed isolation structures. An ILD stressor (140) is then deposited over the transistor region such that the ILD stressor is adjacent to sidewalls of the source/drain structure thereby coupling the ILD stressor to the source/drain stressor. The ILD stressor is preferably compressive or tensile silicon nitride and the source/drain structure is preferably silicon germanium or silicon carbon.

    Abstract: A semiconductor structure and a method of fabricating the same in which strain enhancement is achieved for both nFET and pFET devices is provided. In particular, the present invention provides at least one spacerless FET for stronger strain enhancement and defect reduction. The at least one spacerless FET can be a pFET, an nFET, or a combination thereof, with spacerless pFETs being particularly preferred since pFETs are generally fabricated to have a greater width than nFETs. The at least one spacerless FET allows to provide a stress inducing liner in closer proximity to the device channel than prior art structures including FETs having spacers. The spacerless FET is achieved without negatively affecting the resistance of the corresponding silicided source/drain diffusion contacts, which do not encroach underneath the spacerless FET.
