摘要: Embodiments relate to a method of manufacturing an image sensor which includes forming a plurality of lower layers over a semiconductor substrate. A first passivation layer may be formed over the lower layers to protect the lower layers. The first passivation layer may be formed in a pixel region and a peripheral region with different thicknesses. A spin-on-glass (SOG) layer may be formed over the first passivation layer. A second passivation layer may be formed over the SOG layer. Array etching may be used to form a concave area in the semiconductor substrate. A plurality of micro lenses may be formed over the bottom surface of the concave area.
