    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 CMOS image sensor includes a pinned photodiode and a transfer gate that are formed using a thick mask that is self-aligned to at least one edge of the polysilicon gate structure to facilitate both the formation of a deep implant and to provide proper alignment between the photodiode implant and the gate. In one embodiment a drain side implant is formed concurrently with the deep n-type implant of the photodiode. After the deep implant, the mask is removed and a shallow p+ implant is formed to complete the photodiode. In another embodiment, the polysilicon is etched to define only a drain side edge, a shallow drain side implant is performed, and then a thick mask is provided and used to complete the gate structure, and is retained during the subsequent high energy implant. Alternatively, the high energy implant is performed prior to the shallow drain side implant.

    摘要: A process for fabricating a capacitor in a microcircuit, and the capacitor so fabricated. A first layer of a polycrystalline semiconductor, preferably polysilicon, is deposited. A layer of a binary metallic conductor, preferably tungsten silicide, is deposited on the first layer of polycrystalline semiconductor, and is annealed in an oxidizing atmosphere to produce an oxide layer that serves as the dielectric of the capacitor. A second layer of a polycrystalline semiconductor, also preferably polysilicon, is deposited on the oxide layer. The physical properties (index of refraction, charge to breakdown, breakdown voltage) of the dielectric so created are superior to those of the prior art dielectrics.
