IMAGE SENSOR - A simplified explanation of the abstract
This abstract first appeared for US patent application 17856140 titled 'IMAGE SENSOR
Simplified Explanation
The patent application describes an image sensor technology that includes various components to improve image quality and prevent interference between adjacent color filters.
- The image sensor includes a substrate, which is the base material for the sensor.
- A pixel isolation pattern is created in the substrate to define individual pixel regions.
- Color filters are placed on the substrate, corresponding to the unit pixel regions.
- A low-refractive index pattern is introduced between adjacent color filters to partially isolate them from direct contact with each other. This helps to prevent interference and improve image quality.
- An insulating structure is added between the substrate and the color filters.
- A light blocking pattern is vertically overlapped with the pixel isolation pattern. This pattern is within the insulating structure and is isolated from direct contact with the low-refractive index pattern. The light blocking pattern helps to prevent unwanted light from entering the sensor and affecting image quality.
Potential applications of this technology:
- Digital cameras
- Smartphones
- Surveillance cameras
- Medical imaging devices
Problems solved by this technology:
- Interference between adjacent color filters, which can degrade image quality.
- Unwanted light entering the sensor and affecting image quality.
Benefits of this technology:
- Improved image quality
- Enhanced color accuracy
- Reduced interference between color filters
- Better control over unwanted light
Original Abstract Submitted
An image sensor includes a substrate, a pixel isolation pattern in the substrate and defining unit pixel regions in the substrate, color filters on the substrate and corresponding to the unit pixel regions, respectively, a low-refractive index pattern between adjacent color filters of the color filters to at least partially isolate the adjacent color filters from direct contact with each other, an insulating structure between the substrate and the color filters, and a light blocking pattern vertically overlapping with the pixel isolation pattern. The light blocking pattern is within the insulating structure and is isolated from direct contact with the low-refractive index pattern.
