ABSTRACT:
An image sensor and a method of manufacturing the same are disclosed. When forming an impurity region for a photodiode, the photodiode can be exposed by reducing the impurity region. Thus, a depletion region of the photodiode, formed when the sensor operates, extends to the exposed surface of the photodiode through the inner region of the photodiode, so that it is possible for the photodiode to normally absorb short wavelength light as well as long wavelength light at its depletion region.Also, the uniformity of the generation of photo electrons depending on the different colors of lights can be optimized, and the color presentation quality can be further enhanced.
