    Abstract: Disclosed are embodiments of improved MOSFET and CMOS structures that provides for increased control over short channel effects. Also disclosed are embodiments of associated methods of forming these structures. The embodiments suppress short channel effects by incorporating buried isolation regions into a transistor below source/drain extension regions and between deep source/drain regions and the channel region and, particularly, between deep source/drain regions and the halo regions. Buried isolation regions between the deep source/drain regions and the channel region minimize drain induced barrier lowering (DIBL) as well as punch through. Additionally, because the deep source/drain regions and halo regions are separated by the buried isolation regions, side-wall junction capacitance and junction leakage are also minimized.

    Abstract: In a metal-oxide semiconductor (MOS) transistor with an elevated source/drain structure and in a method of fabricating the MOS transistor with the elevated source/drain structure using a selective epitaxy growth (SEG) process, a source/drain extension junction is formed after an epi-layer is formed, thereby preventing degradation of the source/drain junction region. In addition, the source/drain extension junction is partially overlapped by a lower portion of the gate layer, since two gate spacers are formed and two elevated source/drain layers are formed in accordance with the SEG process. This mitigates the short channel effect and reduces sheet resistance in the source/drain layers and the gate layer.

    Abstract: 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.

    Abstract: A method of fabricating a trench isolation structure in a high-density semiconductor device that provides an isolation characteristic that is independent of the properties of adjacent MOS transistor devices, wherein a first trench in a first isolation area and a second trench implanted are formed on a semiconductor substrate, a nitrogen (N)-rich silicon layer is formed on the sidewall in a second isolation area, a subsequent oxidation process may be employed to fabricate oxide layers, each having a different thickness, on the sidewall surfaces of the first and second trenches. When the first and second oxide-layered trenches are filled with a stress relief liner and a dielectric material, the different thicknesses of the oxides prevent leakage currents from flowing to an adjacent semiconductor device, regardless of the doping properties of each device.

    Abstract: A method of manufacturing a bipolar device including pre-treatment using germane gas and a bipolar device manufactured by the same. The method includes forming a single crystalline silicon layer for a base region on a collector region; and forming a polysilicon layer for an emitter region thereon. Here, before the polysilicon layer is formed, the single crystalline silicon layer is pre-treated using germane gas. Thus, an oxide layer is removed from the single crystalline silicon layer, and a germanium layer is formed on the single crystalline silicon layer, thus preventing Si-rearrangement.
