    摘要: A multi-layered structure of a semiconducotr device includes a substrate, and a heteroepitaxial layer having a low dislocation defect density on the substrate. The heteroepitaxial layer consists of a main epitaxial layer and at least one intermediate epitaxial layer sandwished in the main epitaxial layer. At their interface, the heteroepitaxial layer, i.e., the bottom portion of the main epitaxial layer, and the substrate have different lattice constants. Also, the intermediate epitaxial layer has a different lattice constant from that of the portions of the main epitaxial layer contiguous to the intermediate epitaxial layer. The intermediate epitaxial layer also has a thickness smaller than the net thickness of the main epitaxial layer such that the intermediate epitaxial layer absorbs the strain in the heteroepitaxial layer. Thus, it is possible to obtain a multi-layered structure comprising an epitaxial layer that is relatively thin and has a low dislocation defect density.

    摘要: A transistor includes a semiconductor substrate that has a first surface of a {100} crystal plane, a second surface of the {100} crystal plane having a height lower than that of the first surface, and a third surface of a {111} crystal plane connecting the first surface to the second surface. First heavily doped impurity regions are formed under the second surface. A gate structure is formed on the first surface. An epitaxial layer is formed on the second surface and the third surface. Second heavily doped impurity regions are formed at both sides of the gate structure. The second heavily doped impurity regions have side faces of the {111} crystal plane so that a short channel effect generated between the impurity regions may be prevented.

    摘要: There is provided a method of fabricating a MOS transistor using a total gate silicidation process. The method includes forming an insulated gate pattern on a semiconductor substrate. The insulated gate pattern includes a silicon pattern and a sacrificial layer pattern, which are sequentially stacked. Spacers covering sidewalls of the gate pattern are formed, and source/drain regions are formed by injecting impurity ions into the semiconductor substrate using the spacers and the gate pattern as ion injection masks. The silicon pattern is exposed by removing the sacrificial layer pattern on the semiconductor substrate having the source/drain regions. The exposed silicon pattern is fully converted into a gate silicide layer, and concurrently a source/drain silicide layer is selectively formed on the surface of the source/drain regions.

    摘要: According to some embodiments of the invention, there is provided line photo masks that includes transistors having reinforcement layer patterns and methods of forming the same. The transistors and the methods provide a way of compensating a partially removed amount of a strained silicon layer during semiconductor fabrication processes. To the end, at least one gate pattern is disposed on an active region of a semiconductor substrate. Reinforcement layer patterns are formed to extend respectively from sidewalls of the gate pattern and disposed on a main surface of the semiconductor substrate. Each reinforcement layer pattern partially exposes each sidewall of the gate pattern. Impurity regions are disposed in the reinforcement layer patterns and the active region of the semiconductor substrate and overlap the gate pattern. Spacer patterns are disposed on the reinforcement layer patterns and partially cover the sidewalls of the gate pattern.
