Image sensor and process thereof

摘要

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.

1. An image sensor, comprising:
a plurality of color filters located on a substrate; and an anti-reflective layer located between the substrate and the color filters and directly below the color filters, parts of the anti-reflective layer corresponding to at least two of the color filters having different thicknesses, wherein the bottom surfaces of the color filters are not coplanar.
