Abstract
An image sensor may include four unit pixels constituting a shared pixel in a 2*2 structure; and a Deep Trench Isolation (DTI) structure isolating the four unit pixels from each other. The DTI structure may include an inner DTI structure inside the shared pixel and an outer DTI structure surrounding the shared pixel. The inner DTI structure may include a first DTI structure passing through a center of the shared pixel and extending in a first direction or a second direction and a second DTI structure extending toward the center of the shared pixel in a direction perpendicular to a direction in which the first DTI structure extends. The shared pixel may include a DTI Center Cut (DCC) region between the first DTI structure and the second DTI structure in a direction in which the second DTI structure extends.
