Abstract
A solid-state image sensor capable of improving sensing quality and a related manufacturing method are provided. The method includes steps of forming a plurality of photosensor elements on a substrate; forming a plurality of transfer electrodes on the substrate; forming a plurality of color filters on the photosensor elements and the transfer electrodes; forming a light-shielding film between two adjacent color filters; and forming a microlens above each color filter. The light shielding film is capable of blocking constituents of light filtered by adjacent color filters, preventing a bad image quality due to the reason that a photosensor element senses the constituents of light filtered by different color filters respectively.
