Abstract
Provided is a color image sensor including: a silicon semiconductor chip housed in a package and having a plurality of pixels; an optical glass formed on an upper portion of the silicon semiconductor chip and having a color filter pattern formed thereon; and a window glass formed on the optical glass. According to embodiments of the present invention, color interference between neighboring pixels can be minimized, and the size of the silicon semiconductor chip can be designed smaller under the same color separation condition, which is economical.
