IMAGE SENSOR - A simplified explanation of the abstract
This abstract first appeared for US patent application 20240162257 titled 'IMAGE SENSOR
Simplified Explanation
The image sensor described in the patent application includes a substrate with a pixel region, a floating diffusion region within the pixel region, multiple photoelectric conversion regions surrounding the floating diffusion region, and several transmission gates adjacent to the photoelectric conversion regions. Each transmission gate consists of a first buried gate, a second buried gate, and a gate connection between the two buried gates. Additionally, spacers are present on the side walls of the transmission gates, with each spacer located between the side walls of the gates and the floating diffusion region in a plan view.
- The image sensor features a unique design with transmission gates that include first and second buried gates, as well as gate connections, to improve performance and functionality.
- The presence of spacers on the side walls of the transmission gates helps to optimize the operation of the sensor and enhance image quality.
