摘要： A semiconductor fabrication process includes forming isolation structures on either side of a transistor region, forming a gate structure overlying the transistor region, removing source/drain regions to form source/drain recesses, removing portions of the isolation structures to form recessed isolation structures, 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 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.

摘要： An electronic device can include a transistor structure of a first conductivity type, a field isolation region, and a layer of a first stress type overlying the field isolation region. For example, the transistor structure may be a p-channel transistor structure and the first stress type may be tensile, or the transistor structure may be an n-channel transistor structure and the first stress type may be compressive. The transistor structure can include a channel region that lies within an active region. An edge of the active region includes the interface between the channel region and the field isolation region. From a top view, the layer can include an edge the lies near the edge of the active region. The positional relationship between the edges can affect carrier mobility within the channel region of the transistor structure.

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.
