    摘要: An integrated circuit structure comprises at least one pair of complementary transistors on a substrate. The pair of complementary transistors includes a first transistor and a second transistor. In addition, only one stress-producing layer is on the first transistor and the second transistor and applies tensile strain force on the first transistor and the second transistor. The first transistor has a first channel region, a gate insulator on the first channel region, and a deuterium region between the first channel region and the gate insulator. The second transistor has a germanium doped channel region, as well as the same gate insulator on the germanium doped channel region, and the same deuterium region between the germanium doped channel region and the gate insulator.

    摘要: An integrated circuit (IC) is provided that includes at least one static random access memory (SRAM) cell wherein performance of the SRAM cell is enhanced, yet with good stability and writability. In particular, the present invention provides an IC including at least one SRAM cell wherein the gamma ratio is about 1 or greater. The gamma ratio is increased with degraded pFET device performance. Morever, in the inventive IC there is no stress liner boundary present in the SRAM region and ion variation for all devices is reduced as compared to that of a conventional SRAM structure. The present invention provides an integrated circuit (IC) that comprises at least one SRAM cell including at least one nFET and at least one pFET; and a continuous relaxed stressed liner located above and adjoining the nFET and the pFET.

    摘要: 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.

    摘要: A planar pass gate NFET is designed with the same width as a planar pull-down NFET. To optimize a beta ratio between the planar pull-down NFET and an adjoined planar pass gate NFET, the threshold voltage of the planar pass gate NFET is increased by providing a different high-k metal gate stack to the planar pass gate NFET than to the planar pull-down NFET. Particularly, a threshold voltage adjustment dielectric layer, which is formed over a high-k dielectric layer, is preserved in the planar pass gate NFET and removed in the planar pull-down NFET. The combined NFET active area for the planar pass gate NFET and the planar pull-down NFET is substantially rectangular, which enables a high fidelity printing of the image of the combined NFET active area by lithographic means.
