    摘要: An image sensor having shield structures and methods of forming the same are provided. Generally, the image sensor includes: (i) substrate having at least one photosensitive element formed therein; (ii) a dielectric layer overlying the substrate and the photosensitive element; and (iii) an annular reflective waveguide disposed in the dielectric layer above the photosensitive element to reduce cross-talk between adjacent elements of the sensor while increasing sensitivity of the sensor. In certain embodiments, the sensor further includes a photoshield disposed in the dielectric above the photosensitive element and about the waveguide to further reduce the possibility of cross-talk. Other embodiments are also disclosed.

    摘要: A method and system to form a refractory metal layer over a substrate includes introduction of a reductant, such as PH3 or B2H6, followed by introduction of a tungsten containing compound, such as WF6, to form a tungsten layer. It is believed that the reductant reduces the fluorine content of the tungsten layer while improving the step coverage and resistivity of the tungsten layer. It is believed that the improved characteristics of the tungsten film are attributable to the chemical affinity between the reductants and the tungsten containing compound. The chemical affinity provides better surface mobility of the adsorbed chemical species and better reduction of WF6 at the nucleation stage of the tungsten layer. The method can further include sequentially introducing a reductant, such as PH3 or B2H6, and a tungsten containing compound to deposit a tungsten layer. The formed tungsten layer can be used as a nucleation layer followed by bulk deposition of a tungsten layer utilizing standard CVD techniques. Alternatively, the formed tungsten layer can be used to fill an aperture.
