    摘要: A method for forming a field effect transistor device employs a self-aligned etching of a semiconductor substrate to form a recessed channel region in conjunction with a pair of raised source/drain regions. The method also provides for forming and thermally annealing the pair of source/drain regions prior to forming a pair of lightly doped extension regions within the field effect transistor device. In accord with the foregoing features, the field effect transistor device is fabricated with enhanced performance.

    摘要: A method for forming a strained channel in a semiconductor device is provided, comprises providing of a transistor comprising a gate stack exposed with a gate electrode on a semiconductor substrate, a pair of source/drain regions in the substrate on opposite sides of the gate stack and a pair of spacers on opposing sidewalls of the gate stack. A passivation layer is formed to cover the gate electrode and spacers of the transistor. A passivation layer is formed to cover the gate electrode and the spacers. A recess region is formed in each of the source/drain regions, wherein an edge of the recess region aligns to an outer edge of the spacers. The recess regions are filled with a strain-exerting material, thereby forming a strained channel region in the semiconductor substrate between the source/drain regions.

    摘要: A method of forming an opening on a low-k dielectric layer using a polysilicon hard mask rather than a metal hard mask as used in prior art. A polysilicon hard mask is formed over a low-k dielectric layer and a photoresist layer is formed over the polysilicon hard mask. The photoresist layer is patterned and the polysilicon hard mask is etched with a gas plasma to create exposed portions of the low-k dielectric layer. The photoresist layer in stripped prior to the etching of the exposed portions of the low-k dielectric layer to avoid damage to the low-k dielectric layer.

    摘要: A thin film dielectric layer comprises a top portion and a bottom portion and has density and permittivity characteristics that vary substantially uniformly from the top portion to the bottom portion. Control over the density and/or permittivity is accomplished through varying deposition parameters such as flow rate of constituent process gases or deposition chamber pressure, or through a post deposition treatment, such as plasma treatment or curing.

    摘要: A method for fabricating a strained-silicon semiconductor device to ameliorate undesirable variation in epitaxial film thickness. The layout or component configuration for the proposed semiconductor device is evaluated to determine areas of relatively light or dense population in order to determine whether local-loading-effect defects are likely to occur. If a possibility of such defects occurring exists, a dummy pattern of epitaxial structures may be indicated. If so, the dummy pattern appropriate to the proposed layout is created, incorporated into the mask design, and then implemented on the substrate along with the originally-proposed component configuration.
