IMAGE SENSOR FOR IMPROVING PHOTOSENSITIVITY

摘要

PURPOSE: An image sensor for improving photosensitivity is provided to improve the performance of an image sensor by preventing the crosstalk caused by incident light. CONSTITUTION: An image sensor for improving photosensitivity includes a plurality of photo diodes(PD) and a plurality of micro lenses(ML). The photo diodes(PD) are arranged in a predetermined interval. The micro lenses(ML) are arranged on overlapped parts in order to concentrate incident rays on the photo diodes(PD). In the micro lens(ML), an edge part of a pixel region is larger than a center part of the pixel region. The micro lens is shifted from the edge part to the center part. The image sensor for improving photosensitivity includes a color filter array(CFA), which is installed between the photo diode(PD) and the micro lens(ML).
