IMAGE SENSOR - A simplified explanation of the abstract
This abstract first appeared for US patent application 20240243144 titled 'IMAGE SENSOR
The patent application describes an image sensor with a unique anti-reflection structure and pixel isolator design.
- The image sensor includes a first substrate with a pixel array area and an edge area, along with a first conductive pad in the edge area.
- An anti-reflection structure is located on the second surface of the substrate to reduce glare and improve image quality.
- A pixel isolator within the substrate separates and defines individual pixels for better image resolution.
- A micro lens array is placed on the anti-reflection structure to focus light onto the pixels effectively.
- The anti-reflection structure consists of multiple insulating and conductive layers, with a voltage applied to the conductive layer for optimal performance.
Potential Applications: - Digital cameras - Surveillance systems - Medical imaging devices
Problems Solved: - Glare reduction - Enhanced image quality - Improved pixel isolation
Benefits: - Sharper images - Reduced distortion - Better low-light performance
Commercial Applications: Title: Advanced Image Sensors with Anti-Reflection Technology This technology can be used in high-end digital cameras, security cameras, and medical imaging equipment, providing superior image quality and performance in various applications.
Questions about the technology: 1. How does the anti-reflection structure improve image quality? 2. What are the advantages of using a pixel isolator in the image sensor design?
Original Abstract Submitted
provided is an image sensor, which includes a first substrate that has a first surface and a second surface opposite to the first surface, and includes a pixel array area and an edge area, the edge area including a first conductive pad; an anti-reflection structure on the second surface; a pixel isolator in the first substrate and defining and separating pixels; and a micro lens array that is disposed on the anti-reflection structure, in which the anti-reflection structure includes a first insulating layer, a conductive layer, a second insulating layer, and a third insulating layer sequentially stacked, the conductive layer is on the pixel array area, and is not at least in a portion of the edge area where the first conductive pad is arranged, and a voltage is configured to be applied to the conductive layer.
