IMAGE SENSOR - A simplified explanation of the abstract
This abstract first appeared for US patent application 18067393 titled 'IMAGE SENSOR
Simplified Explanation
The abstract describes an image sensor with two adjacent pixel regions on a substrate. The substrate has two surfaces and a pixel isolation pattern to define the pixel regions. The first pixel region has a transfer gate, a floating diffusion region, and a first ground dopant region. The second pixel region has a second ground dopant region. The bottom surface of the first ground dopant region is at a lower level than the bottom surface of the floating diffusion region.
- The image sensor has two adjacent pixel regions on a substrate. - The substrate has two surfaces and a pixel isolation pattern to define the pixel regions. - The first pixel region includes a transfer gate, a floating diffusion region, and a first ground dopant region. - The second pixel region includes a second ground dopant region. - The bottom surface of the first ground dopant region is at a lower level than the bottom surface of the floating diffusion region.
Original Abstract Submitted
An image sensor includes a substrate including first and second pixel regions adjacent to each other, the substrate including first and second surfaces opposite to each other, a pixel isolation pattern in the substrate to define the first and second pixel regions, a transfer gate on the first surface of the substrate of the first pixel region, a floating diffusion region adjacent to a side of the transfer gate, a first ground dopant region adjacent to the first surface of the substrate in the first pixel region, and a second ground dopant region adjacent to the first surface of the substrate in the second pixel region. A bottom surface of the first ground dopant region is located at a lower level than a bottom surface of the floating diffusion region.
