  • Method for forming imagers
    Patent number: 8795559
    Abstract: A micro-lens array with reduced or no empty space between individual micro-lenses and a method for forming same. The micro-lens array is formed by patterning a first set of micro-lens material in a checkerboard pattern on a substrate. The first set of micro-lens material is reflowed and cured into first micro-lenses impervious to subsequent reflows. Then, a second set of micro-lens material is patterned in spaces among the first micro-lenses, reflowed and cured into second micro-lenses. The reflows and cures can be conducted under different conditions, and the micro-lenses may be differently sized. The conditions of the reflows can be chosen to ensure that the focal lengths of micro-lenses are optimized for maximum sensor signal.

  • Micro-lenses for CMOS imagers and method for manufacturing micro-lenses
    Patent number: 8390931
    Abstract: A micro-lens and a method for forming the micro-lens is provided. A micro-lens includes a substrate and lens material located within the substrate, the substrate having a recessed area serving as a mold for the lens material. The recessed can be shaped such that the lens material corrects for optical aberrations. The micro-lens can be part of a micro-lens array. The recessed area can serve as a mold for lens material for the micro-lens array and can be shaped such that the micro-lens array includes arcuate, non-spherical, or non-symmetrical micro-lenses.

  • Imager with tuned color filter
    Patent number: 8105862
    Abstract: An optimized color filter array is formed in, above or below one or more damascene layers. The color filter array includes filter regions which are configured to optimize the combined optical properties of the layers of the device to maximize the intensity of the particular wavelength of light incident to a respective underlying photodiode.

  • Method of forming a uniform color filter array
    Patent number: 8071416
    Abstract: A method of forming a uniform color filter array. In one embodiment, a first compensation layer is formed over a non-planar color filter array and is patterned to form material structures. A second compensation layer is blanket deposited over the first layer. A technique, such as etching or polishing, is then performed to remove the first and second compensation layers, creating a substantially planar color filter array surface. In another embodiment, the planar color filter array is formed in a recessed trench.
