IMAGE SENSOR - A simplified explanation of the abstract
This abstract first appeared for US patent application 18416388 titled 'IMAGE SENSOR
The image sensor described in the patent application consists of two structures stacked vertically: the first structure containing a pixel region with a photoelectric conversion unit and a floating diffusion region, and the second structure containing a pixel region with a source-follower transistor.
- The first structure includes a first interlayer insulating layer and a first pixel pad connected to the floating diffusion region.
- The second structure includes a second interlayer insulating layer and a second pixel pad connected to the gate of the source-follower transistor.
- A coupling prevention line surrounds the first and second pixel pads, electrically connected to the source region of the source-follower transistor.
Potential Applications: - This technology can be used in digital cameras, smartphones, and other devices requiring high-quality image sensors. - It can also be applied in medical imaging equipment, surveillance cameras, and automotive cameras.
Problems Solved: - The image sensor addresses the need for improved pixel structures and interconnection methods to enhance image quality and performance. - It solves the issue of signal coupling between pixel pads in close proximity.
Benefits: - Enhanced image quality and sensitivity. - Improved signal processing and noise reduction. - Higher resolution and better overall performance in imaging applications.
Commercial Applications: Title: Advanced Image Sensor Technology for Enhanced Imaging Devices This technology can be utilized in the development of next-generation digital cameras, smartphones, medical imaging devices, surveillance systems, and automotive cameras, catering to a wide range of industries and consumer electronics markets.
Questions about Image Sensor Technology: 1. How does the coupling prevention line improve the performance of the image sensor?
The coupling prevention line helps reduce signal interference and crosstalk between the pixel pads, resulting in clearer and more accurate image capture.
2. What are the key advantages of using a stacked structure in image sensor design?
Stacked structures allow for more compact and efficient sensor designs, enabling higher pixel densities and improved overall performance.
