Abstract
A CMOS image sensor and method for fabricating the same is disclosed that reconditions, repairs and/or protects a surface of a photodiode area and improves characteristics of the image sensor. The method includes forming a photodiode area and a plurality of transistors, implanting a predetermined ion into a surface of the photodiode area, and forming a surface oxide film on the surface of the photodiode area by oxidation. Therefore, it is possible to recover or repair the photodiode surface damaged during various fabrication processes, reduce or minimize surface leakage of the photodiode during subsequent processes, and improve image sensor characteristics by increasing incident light on the photodiode.
