IMAGE SENSOR AND ELECTRONIC SYSTEM INCLUDING THE SAME - A simplified explanation of the abstract
This abstract first appeared for US patent application 20240379696 titled 'IMAGE SENSOR AND ELECTRONIC SYSTEM INCLUDING THE SAME
Simplified Explanation:
The patent application describes an image sensor with a unique design that includes a floating diffusion region, photodiodes, and an inter-pixel overflow (ipo) barrier within the sensing area.
- The image sensor has a substrate with a sensing area.
- A floating diffusion region is located within the sensing area.
- Multiple photodiodes are arranged around the floating diffusion region.
- An inter-pixel overflow (ipo) barrier is in contact with each photodiode.
- The ipo barrier overlaps the floating diffusion region vertically but is spaced apart from it within the sensing area.
Key Features and Innovation:
- Innovative design of an image sensor with a floating diffusion region and ipo barrier.
- Efficient arrangement of photodiodes around the floating diffusion region.
- Vertical overlapping of the ipo barrier with the floating diffusion region for improved performance.
Potential Applications:
- Digital cameras
- Smartphones
- Surveillance systems
- Medical imaging devices
Problems Solved:
- Reduced crosstalk between photodiodes.
- Improved image quality and sensitivity.
- Enhanced signal processing capabilities.
Benefits:
- Higher quality images.
- Increased sensitivity in low-light conditions.
- Improved overall performance of image sensors.
Commercial Applications:
The technology can be utilized in various commercial applications such as digital cameras, smartphones, surveillance systems, and medical imaging devices. The improved image quality and sensitivity offered by this innovation can lead to better products and enhanced user experiences in these industries.
Questions about Image Sensors:
1. How does the ipo barrier help in reducing crosstalk between photodiodes? 2. What are the potential challenges in implementing this innovative image sensor design in commercial products?
Original Abstract Submitted
an image sensor includes a substrate having a sensing area, a floating diffusion region arranged in the sensing area, a plurality of photodiodes arranged around the floating diffusion region in the sensing area, and an inter-pixel overflow (ipo) barrier in contact with each of the plurality of photodiodes, the ipo barrier overlapping the floating diffusion region in a vertical direction at a position vertically spaced apart from the floating diffusion region within the sensing area.
