  • Publication number: 20170186795
    Abstract: An image sensor is provided in the present invention. The image sensor includes a continuous microlens including a plurality of top sub lenses connected with one another and a plurality of bottom sub lenses disposed corresponding to the top sub lenses. The continuous microlens maybe used to enhance quantum efficiency. The top sub lens and the bottom sub lens condense light by two steps within a shorter distance and make the light focused on a sensing element, and the continuous microlens may be applied without the limitation about the size of the pixel region accordingly. Additionally, the sensitivity and the uniformity thereof may be enhanced because of the shorter distance between the bottom sub lens and the sensing element. A transmittance of a color filter layer disposed corresponding to the bottom sub lens may also be enhanced.

  • Patent number: 8084289
    Abstract: A method of fabricating an image sensor device is provided. First, a substrate comprising a pixel array region and a pad region is provided. A patterned metal layer and a first planarization layer having an opening exposing the patterned metal layer in the pad region are sequentially formed on the substrate. A color filter array is formed on the first planarization layer in the pixel array region. A second planarization layer is formed to cover the color filter array and filled into the opening. A plurality of microlens is formed above the color filter array on the second planarization layer. A capping layer is conformally formed on the microlens and the second planarization layer. An etching step is performed to remove the capping layer and the second planarization layer in the opening so as to expose the patterned metal layer in the pad region.
