IMAGE SENSOR - A simplified explanation of the abstract
This abstract first appeared for US patent application 18454110 titled 'IMAGE SENSOR
Simplified Explanation
The image sensor described in the patent application includes a semiconductor substrate with two adjacent pixels, separated by a pixel isolation structure. An anti-reflection layer covers the pixels and the isolation structure, and a through via structure is present in a through via hole in the anti-reflection layer and the substrate.
- The image sensor has a pixel isolation structure to prevent crosstalk between adjacent pixels.
- An anti-reflection layer is used to reduce unwanted reflections and improve image quality.
- The through via structure allows for electrical connections between different layers of the sensor.
- The through via structure includes a first conductive layer and a second conductive layer for efficient signal transmission.
- The materials used in the anti-reflection layer and the conductive layers are carefully chosen for optimal performance.
