    摘要: The present invention is a CMOS image sensor and its method of fabrication. This invention provides an efficient structure to improve the quantum efficiency of a CMOS image sensor with borderless contact. The image sensor comprises a N-well/P-substrate type photodiode with borderless contact and dielectric structure covering the photodiode region. The dielectric structure is located between the photodiode and the interlevel dielectric (ILD) and is used as a buffer layer for the borderless contact. The method of fabricating a high performance photodiode comprises forming a photodiode in the n-well region of a shallow trench, and embedding a dielectric material between the ILD oxide and the photodiode having a refraction index higher than the ILD oxide.

    摘要: A method for making an array of photodiodes with more uniform optical spectral response for the red, green, and blue pixel cells on a CMOS color imager is achieved. After forming a field oxide on a substrate to electrically isolate device areas for CMOS circuits, an array of deep N doped wells is formed for photodiodes for the long wavelength red pixel cells. An array of P doped well regions is formed adjacent to and interlaced with the N doped wells. Shallow diffused N+ regions are formed within the P doped wells for the shorter wavelength green and blue color pixels cells. The shallow diffused photodiodes improve the quantum efficiency (QE), and provide a color imager with improved color fidelity. An insulating layer and appropriate dye materials are deposited and patterned over the photodiodes to provide the array of color pixel cells. The N and P doped wells are also used for the supporting FET CMOS circuits to provide a cost-effective manufacturing process.

    摘要: A method of fabricating a stripe photodiode element, for an image sensor cell, has been developed. The stripe photodiode element is comprised of a narrow width, serpentine shaped, lightly doped N type region, in a P well region. The use of the serpentine shaped region results in increased photon collection area, when compared to counterparts fabricated using non-serpentine shaped patterns. In addition the use of the serpentine shaped N type regions allow both vertical, as well as horizontal depletion regions, to result, thus increasing the quantum efficiency of the photodiode element. The combination of narrow width, and a reduced dopant level, for the N type serpentine shaped region, result in a fully depleted photodiode element.
