IMAGE SENSOR - A simplified explanation of the abstract
This abstract first appeared for US patent application 18526322 titled 'IMAGE SENSOR
The abstract describes an image sensor with a 2*2 structure consisting of four unit pixels forming a shared pixel, isolated by a Deep Trench Isolation (DTI) structure. The DTI structure includes an inner DTI structure within the shared pixel and an outer DTI structure surrounding it. The inner DTI structure comprises a first DTI structure passing through the center of the shared pixel in two directions and a second DTI structure extending towards the center in a perpendicular direction. A DTI Center Cut (DCC) region is present between the first and second DTI structures.

Original Abstract Submitted
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.
