IMAGE SENSOR - A simplified explanation of the abstract
This abstract first appeared for US patent application 20240321913 titled 'IMAGE SENSOR
The patent application 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 different 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.
- Four unit pixels form a shared pixel in a 2*2 structure.
- Deep trench isolation (DTI) structure isolates the unit pixels from each other.
- Inner DTI structure inside the shared pixel and outer DTI structure surrounding it.
- First DTI structure passes through the center of the shared pixel in two directions.
- Second DTI structure extends towards the center in a perpendicular direction.
- DTI center cut (DCC) region between the first and second DTI structures.
Potential Applications: - High-resolution image sensors - Digital cameras - Surveillance systems - Medical imaging devices
Problems Solved: - Improved pixel isolation - Enhanced image quality - Reduction of crosstalk between pixels
Benefits: - Higher quality images - Increased sensor performance - Enhanced overall device functionality
Commercial Applications: Title: Advanced Image Sensor Technology for Enhanced Performance in Digital Cameras This technology can be utilized in the development of high-quality digital cameras, improving image resolution and overall performance. It can also be integrated into surveillance systems and medical imaging devices for enhanced image capture capabilities.
Questions about the technology: 1. How does the DTI structure improve pixel isolation in the image sensor? 2. What are the potential market implications of implementing this advanced image sensor technology in digital cameras?
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.
