Abstract:
Provided is an image sensor including an overcoating layer and at least two micro lenses formed on the overcoating layer. The image sensor is characterized in that the overcoating layer positioned below a clearance between the micro lenses is etched such that curved surfaces of the micro lenses extend to the etched overcoating layer, and a contamination in the bonding pad can be prevented.
