  • Image sensor and process thereof
    Patent number: 8779484
    Abstract: An image sensor includes a plurality of color filters and an anti-reflective layer. The color filters are located on a substrate. The anti-reflective layer is located between the substrate and the color filters, and parts of the anti-reflective layer corresponding to at least two of the color filters have different thicknesses. Moreover, an image sensing process including the following steps is also provided. An anti-reflective layer is formed on a substrate. A plurality of color filters is formed on the anti-reflective layer, wherein parts of the anti-reflective layer right below at least two of the color filters have different thicknesses.
    Type: Grant
