    摘要: A semiconductor fabrication process has recessed stress-inducing source/drain (SISD) structures that are formed using a multiple phase formation process. The SISD structures are semiconductor structures having a lattice constant that differs from a lattice constant of the semiconductor substrate in which the source/drain structures are recessed. The SISD structures preferably include semiconductor compound having a first element (e.g., silicon) and a second element (e.g., germanium or carbon). The SISD structure has a composition gradient wherein the percentage of the second element varies from the upper surface of the source/drain structure to a lower surface of the SISD structure. The SISD structure may include a first layer with a first composition of the semiconductor compound underlying a second layer with a second composition of the semiconductor compound. The second layer may include an impurity and have a higher percentage of the second element that the first layer.

    摘要: Mechanical stress control may be achieved using materials having selected elastic moduli. These materials may be selectively formed by implantation, may be provided as a plurality of buried layers interposed between the substrate and the active area, and may be formed by replacing selected portions of one or more buried layers. Any one or more of these methods may be used in combination. Mechanical stress control may be useful in the channel region of a semiconductor device to maximize its performance. In addition, these same techniques and structures may be used for other purposes besides mechanical stress control.

    摘要: A semiconductor substrate having a silicon layer is provided. In one embodiment, the substrate is a silicon-on-insulator (SOI) substrate having an oxide layer underlying the silicon layer. An amorphous or polycrystalline silicon germanium layer is formed overlying the silicon layer. Alternatively, germanium is implanted into a top portion of the silicon layer to form an amorphous silicon germanium layer. The silicon germanium layer is then oxidized to convert the silicon germanium layer into a silicon dioxide layer and to convert at least a portion of the silicon layer into germanium-rich silicon. The silicon dioxide layer is then removed prior to forming transistors using the germanium-rich silicon. In one embodiment, the germanium-rich silicon is selectively formed using a patterned masking layer over the silicon layer and under the silicon germanium layer. Alternatively, isolation regions may be used to define local regions of the substrate in which the germanium-rich silicon is formed.

    摘要: Field isolation regions are formed using oxidation-resistant spacers or plugs that completely fill trenches within a semiconductor substrate prior to forming the field isolation regions. The spacers or plugs help to reduce encroachment of the field isolation regions under the spacers or plugs. The structure used as an oxidation mask for the field isolation process may include a silicon-containing member that is thicker than an overlying oxidation-resistant member. The thicker silicon-containing member may be capable of tolerating higher stress before defects in an underlying pad layer or substrate are formed.
