Abstract:
1. A CMOS (complementary metal oxide semiconductor) image sensor comprising: a plurality of photodiodes a predetermined distance apart from each other on a semiconductor substrate; an insulation layer on an entire surface of the semiconductor substrate; a passivation layer on the insulation layer; a plurality of color filters on the passivation layer corresponding to the photodiodes; a planarization layer on an entire surface of the semiconductor substrate including the color filters; and a microlens formed on the planarization layer corresponding to each of the color filters and having a bottom diameter of 2.5 to 3.0 μm and a thickness of 0.41 to 0.49 μm with respect to a center of the bottom diameter of the microlens, wherein the microlens is adapted to focus light on the photodiode.
