  • Method of forming elevated photosensor and resulting structure
    Publication number: 20070284686
    Abstract: Elevated crystal silicon photosensors for imagers pixels, each photosensor formed of crystal silicon above the surface of a substrate that has pixel circuitry formed thereon. The imager has a high fill factor and good imaging properties due to the crystal silicon photosensor.

  • Methods to make sidewall light shields for color filter array
    Publication number: 20070237888
    Abstract: Methods of forming color filters having a light blocking material therebetween. A color filter is formed such that a trench is defined between a color filter and an adjacent color filter. The trench may be formed by exposing the color filter to polymerizing conditions such as, for example, ultraviolet radiation and heat. The trench may also be formed by etching between adjacent color filters. A material is formed within the trench.
