IMAGE SENSOR AND METHOD OF FABRICATING THE SAME - A simplified explanation of the abstract
This abstract first appeared for US patent application 17991063 titled 'IMAGE SENSOR AND METHOD OF FABRICATING THE SAME
Simplified Explanation
The patent application describes an image sensor that includes a substrate with a pixel area and an optically black area. The substrate has two surfaces, and there are color filters on the second surface of the substrate in the pixel area. Additionally, there is a first optically black pattern in a recess on the second surface of the substrate in the optically black area. The first optically black pattern is made of the same material as one of the color filters, and the top surfaces of the color filters and the first optically black pattern are at the same level.
- The image sensor has a substrate with a pixel area and an optically black area.
- Color filters are placed on the second surface of the substrate in the pixel area.
- A first optically black pattern is present in a recess on the second surface of the substrate in the optically black area.
- The first optically black pattern is made of the same material as one of the color filters.
- The top surfaces of the color filters and the first optically black pattern are at the same level.
Potential Applications
- Digital cameras
- Smartphone cameras
- Surveillance cameras
- Medical imaging devices
Problems Solved
- Reduction of stray light in image sensors
- Improved image quality by minimizing light leakage
Benefits
- Enhanced image sensor performance
- Improved color accuracy

Original Abstract Submitted
Disclosed is an image sensor comprising a substrate including a pixel area and an optically black area and having a first surface and a second surface that are opposite to each other, a plurality of color filters on the second surface of the substrate on the pixel area, and a first optically black pattern in a first recess on the second surface of the substrate on the optically black area. The first optically black pattern includes a material that is the same as a material of one of the color filters. Top surfaces of the color filters and a top surface of the first optically black pattern are at the same level.
