IMAGE SENSOR - A simplified explanation of the abstract
This abstract first appeared for US patent application 20240250104 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 pixel region with a photoelectric conversion unit and a floating diffusion region.
- The second structure includes a pixel region with a source-follower transistor.
- A first interlayer insulating layer is present on the floating diffusion region in the first structure.
- A second interlayer insulating layer is present on the source-follower transistor in the second structure.
- A coupling prevention line is arranged around the first and second pixel pads and is electrically connected to the source region of the source-follower transistor.
Potential Applications: - Digital cameras - Surveillance systems - Medical imaging devices
Problems Solved: - Improved image sensor performance - Enhanced signal processing capabilities
Benefits: - Higher quality image capture - Increased sensitivity to light - Reduced noise in image processing
Commercial Applications: Title: Advanced Image Sensor Technology for Enhanced Imaging Devices This technology can be utilized in various commercial applications such as digital cameras, surveillance systems, and medical imaging devices, enhancing their performance and image quality.
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 noise and interference in the signal processing, leading to clearer and more accurate image capture.
2. What are the key advantages of using a source-follower transistor in the second structure of the image sensor? The source-follower transistor helps amplify and stabilize the signals from the pixel region, improving the overall performance and sensitivity of the image sensor.
