    摘要: A cobalt silicide process having a titanium-rich/titanium nitride capping layer to improve junction leakage is described. Semiconductor device structures to be silicided are formed in and on a semiconductor substrate. A cobalt layer is deposited overlying the semiconductor device structures. A titanium-rich/titanium nitride capping layer is deposited overlying the cobalt layer. Thereafter, a cobalt silicide layer is formed on the semiconductor device structures. The titanium-rich/titanium nitride capping layer and an unreacted portion of the cobalt layer are removed to complete fabrication of the integrated circuit device.

    摘要: A method of forming a semiconductor device, and a product formed thereby, is provided. The method includes forming a pattern in a mask layer using, for example, double patterning or multi-patterning techniques. The mask is treated to smooth or round sharp corners. In an embodiment in which a positive pattern is formed in the mask, the treatment may comprise a plasma process or an isotropic wet etch. In an embodiment in which a negative pattern is formed in the mask, the treatment may comprise formation of conformal layer over the mask pattern. The conformal layer will have the effect of rounding the sharp corners. Other techniques may be used to smooth or round the corners of the mask.

    摘要: Within a damascene method for forming a microelectronic fabrication, there is employed an etch stop layer comprising a comparatively low dielectric constant dielectric material sub-layer having formed thereupon a comparatively high dielectric constant dielectric material sub-layer. Within the method there is also simultaneously etched: (1) an anti-reflective coating layer from an inter-metal dielectric layer; and (2) the etch stop layer from a contact region. The microelectronic fabrication is formed with enhanced performance and enhanced reliability.

    摘要: There is first provided a substrate 10 and a target layer 12. There is then formed upon the target layer a patterned positive photoresist layer 14. There is then processed the target layer while employing the patterned positive photoresist layer as a mask layer, to thus form a processed target layer and a processed patterned positive photoresist layer. There is then photoexposed 18 the processed patterned positive photoresist layer to enhance its solubility. Finally, there is then stripped from the processed target layer the photoexposed processed patterned positive photoresist layer while employing a solvent.
