Latest Patents
Chin-Kung Chang holds a patent titled "Effective method to improve sub-micron color filter sensitivity". This invention describes an image sensor device and the method for forming it. The structure of the image sensor includes a substrate embedded with photodiodes, an interconnect structure positioned atop the substrate, and a color filter layer situated above the interconnect structure. Notable aspects of the design include the presence of a first microlens array, an overcoat layer, and a second microlens array. A defining feature of this invention is the second microlens possessing a larger radius of curvature than its first counterpart. Both types of microlenses are designed as flat convex lenses, resulting in a thicker second microlens with a shorter focal length being aligned over a thinner first microlens, which has a longer focal length. This arrangement allows for the formation of a light column comprising both microlenses and a color filter region over each photodiode. In an alternate embodiment, the second microlens can be replaced by multiple smaller second microlenses that concentrate light onto a first microlens.
