    摘要: The present invention relates to a semiconductor device structure that includes at least one SRAM cell formed in a substrate. Such SRAM cell comprises two pull-up transistors, two pull-down transistors, and two pass-gate transistors. The pull-down transistors and the pass-gate transistors are substantially similar in channel widths and have substantially similar source-drain doping concentrations, while the SRAM cell has a beta ratio of at least 1.5. The substrate preferably comprises a hybrid substrate with at two isolated sets of regions, while carrier mobility in these two sets of regions differentiates by a factor of at least about 1.5. More preferably, the pull-down transistors of the SRAM cell are formed in one set of regions, and the pass-gate transistors are formed in the other set of regions, so that current flow in the pull-down transistors is larger than that in the pass-gate transistors.

    摘要: Compressive or tensile materials are selectively introduced beneath and in alignment with spacer areas and adjacent to channel areas of a semiconductor substrate to enhance or degrade electron and hole mobility in CMOS circuits. A process entails steps of creating dummy spacers, forming a dielectric mandrel (i.e., mask), removing the dummy spacers, etching recesses into the underlying semiconductor substrate, introducing a compressive or tensile material into a portion of each recess, and filling the remainder of each recess with substrate material.

    摘要: Channel depth in a field effect transistor is limited by an intra-layer structure including a discontinuous film or layer formed within a layer or substrate of semiconductor material. Channel depth can thus be controlled much in the manner of SOI or UT-SOI technology but with less expensive substrates and greater flexibility of channel depth control while avoiding floating body effects characteristic of SOI technology. The profile or cross-sectional shape of the discontinuous film may be controlled to an ogee or staircase shape to improve short channel effects and reduce source/drain and extension resistance without increase of capacitance. Materials for the discontinuous film may also be chosen to impose stress on the transistor channel from within the substrate or layer and provide increased levels of such stress to increase carrier mobility. Carrier mobility may be increased in combination with other meritorious effects.

    摘要: A CMOS structure in which the gate-to-drain/source capacitance is reduced as well as various methods of fabricating such a structure are provided. In accordance with the present invention, it has been discovered that the gate-to-drain/source capacitance can be significantly reduced by forming a CMOS structure in which a low-k dielectric material is self-aligned with the gate conductor. A reduction in capacitance between the gate conductor and the contact via ranging from about 30% to greater than 40% has been seen with the inventive structures. Moreover, the total outer-fringe capacitance (gate to outer diffusion+gate to contact via) is reduced between 10-18%. The inventive CMOS structure includes at least one gate region including a gate conductor located a top a surface of a semiconductor substrate; and a low-k dielectric material that is self-aligned to the gate conductor.
