  • Publication number: 20130082309
    Abstract: A method for fabricating a semiconductor device is disclosed. A strained material is formed in a cavity of a substrate and adjacent to an isolation structure in the substrate. The strained material has a corner above the surface of the substrate. The disclosed method provides an improved method for forming the strained material adjacent to the isolation structure with an increased portion in the cavity of the substrate to enhance carrier mobility and upgrade the device performance. The improved formation method is achieved by providing a treatment to redistribute at least a portion of the corner in the cavity.

The strained material has a corner above the surface of the substrate. The disclosed method provides an improved method for forming the strained material adjacent to the isolation structure with an increased portion in the cavity of a substrate to enhance carrier mobility and upgrade the device performance. In an embodiment, the improved formation method is achieved using an etching process to redistribute the strained material by removing at least a portion of the corner to be located in the cavity.
