    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.

    摘要: A method for forming a patterned microelectronics layer within a microelectronics fabrication. There is first provided a substrate employed within a microelectronics fabrication. There is then formed over the substrate an oxygen containing plasma etchable microelectronics layer. There is then formed upon the oxygen containing plasma etchable microelectronics layer a hard mask layer. There is then formed upon the hard mask layer a patterned photoresist layer. There is then etched through use of a first anisotropic plasma etch method the hard mask layer to form a patterned hard mask layer while employing the patterned photoresists layer as a first etch mask layer. The first anisotropic plasma etch method employs an etchant gas composition appropriate for etching a hard mask material from which is formed the hard mask layer. There is then etched through use of a second plasma etch method the patterned photoresist layer from the patterned hard mask layer while employing the patterned hard mask layer as an etch stop layer while simultaneously etching the oxygen containing plasma etchable microelectronics layer while employing at least the patterned hard mask layer as a second etch mask layer to form a patterned oxygen containing plasma etchable microelectronics layer. The second plasma etch method employs an oxygen containing etchant gas composition. The method is particularly useful for forming patterned oxygen containing plasma etchable microelectronics dielectric layers within microelectronics fabrications.

    摘要: A method for preventing formation of photoresist scum. First, a substrate on which a dielectric layer is formed is provided. Next, a non-nitrogen anti-reflective layer is formed on the dielectric layer. Finally, a photoresist pattern layer is formed on the non-nitrogen anti-reflective layer. During the formation of the photoresist pattern layer, the non-nitrogen anti-reflective layer does not react with the photoresist pattern layer, thus not forming photoresist scum. This prevents undesired etching profile and critical dimension (CD) change due to presence of photoresist scum. The non-nitrogen anti-reflective layer can be silicon-rich oxide (SiOx) or hydrocarbon-containing silicon-rich oxide (SiOxCy:H).
