Abstract
Disclosed is an image sensor, which includes a first PD isolation region for determining first to fourth PD regions, an FD isolation region formed between the first to fourth PD regions, and a floating diffusion formed in the FD isolation region. Horizontal distances from a perimeter of the floating diffusion to interfaces between the FD isolation region and the first to fourth PD regions are equal to each other.
