IMAGE SENSORS INCLUDING MICROLENSES HAVING PLURALITY OF CURVATURES AND METHODS OF FABRICATING THE SAME - A simplified explanation of the abstract
This abstract first appeared for US patent application 20240136379 titled 'IMAGE SENSORS INCLUDING MICROLENSES HAVING PLURALITY OF CURVATURES AND METHODS OF FABRICATING THE SAME
Simplified Explanation
The patent application describes an image sensor and its fabrication methods, including a first substrate with pixels arranged in groups, a pixel separation structure, and microlenses overlapping the pixel groups.
- The image sensor includes a first substrate with a plurality of pixels arranged in groups, a pixel separation structure, and microlenses overlapping the pixel groups.
- Each pixel group consists of four pixels arranged in two columns and two rows, separated by a pixel separation structure.
- The microlenses on the first surface of the substrate have a central part with a first curvature and an edge part with a second curvature, where the first curvature is less than the second curvature.
Potential Applications
The technology can be used in digital cameras, smartphones, surveillance systems, and medical imaging devices.
Problems Solved
The innovation solves the problem of improving image quality and resolution in image sensors by optimizing the arrangement of pixels and microlenses.
Benefits
The benefits of this technology include enhanced image quality, higher resolution, improved light sensitivity, and reduced noise in captured images.
Potential Commercial Applications
The technology can be applied in the consumer electronics industry for manufacturing high-quality cameras and imaging devices.
Possible Prior Art
Prior art may include existing image sensor technologies with similar pixel arrangements and microlens structures.
Unanswered Questions
How does the pixel separation structure impact the overall performance of the image sensor?
The pixel separation structure helps to prevent crosstalk between adjacent pixels, but the specific effects on image quality and resolution are not detailed in the abstract.
What materials are used in the fabrication of the microlenses and how does this affect their optical properties?
The abstract does not mention the materials used for the microlenses or how their optical properties are influenced by these materials.
Original Abstract Submitted
image sensors and fabrication methods thereof. for example, the image sensor may include a first substrate having a first surface and a second surface that are opposite to each other, a plurality of pixels provided in the first substrate and arranged in pixel groups, each pixel group including four pixels arranged in two columns and two rows, a pixel separation structure in the first substrate and including a pixel group separation part that separates each pixel group from adjacent pixel groups and a pixel separation part that separates the pixels in each pixel group from each other, and a plurality of microlenses on the first surface and respectively overlapping the plurality of pixel groups. each of the microlenses includes a central part that has a first curvature and an edge part that has a second curvature. the first curvature is less than the second curvature.
