IMAGE SENSOR, METHOD OF MANUFACTURING IMAGE SENSOR, AND ELECTRONIC DEVICE INCLUDING IMAGE SENSOR - A simplified explanation of the abstract
This abstract first appeared for US patent application 17971932 titled 'IMAGE SENSOR, METHOD OF MANUFACTURING IMAGE SENSOR, AND ELECTRONIC DEVICE INCLUDING IMAGE SENSOR
Simplified Explanation
The abstract describes an image sensor that includes a sensor substrate, a spacer layer, and a color separation lens array. The color separation lens array consists of a first lens layer with a sub-wavelength shape dimension and a first peripheral material, as well as a first chemical mechanical polishing (CMP) stop layer.
- The image sensor includes a sensor substrate with light sensing cells.
- A transparent spacer layer is placed on top of the sensor substrate.
- A color separation lens array is arranged on top of the spacer layer.
- The color separation lens array consists of a first lens layer and a first CMP stop layer.
- The first lens layer has a sub-wavelength shape dimension and a first peripheral material.
- The first CMP stop layer covers the entire upper surface of the first lens layer, except for the upper surface of the first nanopost.
Potential applications of this technology:
- Digital cameras
- Smartphones
- Surveillance systems
- Medical imaging devices
Problems solved by this technology:
- Improved color separation and image quality
- Reduction of optical crosstalk between pixels
- Enhanced light sensitivity and efficiency
Benefits of this technology:
- Higher resolution and sharper images
- More accurate color reproduction
- Improved low-light performance
- Compact and thin image sensor design
Original Abstract Submitted
An image sensor includes: a sensor substrate including a plurality of light sensing cells; a spacer layer which is transparent and arranged on an upper side of the sensor substrate; and a color separation lens array arranged on an upper side of the spacer layer. The color separation lens array includes: a first lens layer which includes a first nanopost having a sub-wavelength shape dimension and a first peripheral material provided around the first nanopost; and a first chemical mechanical polishing (CMP) stop layer which is provided on an entire upper surface of the first lens layer except for an upper surface of the first nanopost.
