IMAGE SENSOR - A simplified explanation of the abstract
This abstract first appeared for US patent application 17807026 titled 'IMAGE SENSOR
Simplified Explanation
The patent application describes an image sensor with a pixel array, pixel isolation layers, and pixel circuits. The pixel array consists of photodiodes, color filters, and microlenses arranged in pixel groups. The pixel isolation layers separate the photodiodes and contain silicon oxide and polysilicon.
- The image sensor includes a pixel array with photodiodes, color filters, and microlenses.
- Pixel isolation layers separate the photodiodes and contain silicon oxide and polysilicon.
- The pixel array is divided into pixel groups, each consisting of two or more photodiodes, a color filter, and a microlens.
- Each pixel group has a color filter with a single color.
- The pixel isolation layers are composed of a first layer between pixel groups and a second layer extending in two directions between the photodiodes in each pixel group.
Potential applications of this technology:
- Digital cameras
- Smartphones
- Surveillance systems
- Medical imaging devices
Problems solved by this technology:
- Improved image quality and color accuracy
- Enhanced pixel isolation to prevent cross-talk between photodiodes
- Efficient use of space on the image sensor
Benefits of this technology:
- Higher resolution and sharper images
- Accurate color reproduction
- Compact and efficient design for smaller devices
- Reduced noise and interference in captured images
Original Abstract Submitted
An image sensor includes: a pixel array including a plurality of photodiodes arranged on an upper surface of a substrate, pixel isolation layers extending from the upper surface to a lower surface of the substrate and disposed between the plurality of photodiodes, and pixel circuits. The pixel array includes pixel groups respectively including two or more of the photodiodes, at least one color filter, and at least one microlens. The at least one color filter included in each of the pixel groups has one color, and the pixel isolation layers includes a first pixel isolation layer disposed between the pixel groups and containing silicon oxide and polysilicon; and a second pixel isolation layer containing silicon oxide and extending in a first direction and a second direction, which intersect each other between the two or more photodiodes in each of the pixel groups.
