PHOTOELECTRIC CONVERSION APPARATUS HAVING OVERLAPPED PARTS OF CHARGE HOLDING PORTIONS, IMAGING SYSTEM, AND MOVABLE BODY - A simplified explanation of the abstract
- This abstract for appeared for US patent application number 18330975 Titled 'PHOTOELECTRIC CONVERSION APPARATUS HAVING OVERLAPPED PARTS OF CHARGE HOLDING PORTIONS, IMAGING SYSTEM, AND MOVABLE BODY'
Simplified Explanation
The abstract describes a photoelectric conversion apparatus that consists of pixels. Each pixel has a photoelectric conversion portion, a charge holding portion, and a floating diffusion layer. These components are located in a semiconductor layer of a substrate. The charge holding portion holds the charges generated by the photoelectric conversion portion, and the floating diffusion layer converts the charges into a voltage. In this apparatus, certain parts of the charge holding portion in one pixel and the floating diffusion layer in an adjacent pixel, or certain parts of the charge holding portions or floating diffusion layers in adjacent pixels, overlap each other without physically touching each other. This overlap occurs in the depth direction of the substrate, with a region separating the overlapping parts.
Original Abstract Submitted
A photoelectric conversion apparatus includes pixels having adjacent first and second pixels. The pixels each include, in a semiconductor layer of a substrate, a photoelectric conversion portion that generates charges, a charge holding portion that holds the charges, and a floating diffusion layer that converts the charges into a voltage. At least parts of the charge holding portion in the first pixel and the floating diffusion layer in the second pixel, parts of the charge holding portion in the first pixel and the charge holding portion in the second pixel, and/or parts of the floating diffusion layer in the first pixel and the floating diffusion layer in the second pixel overlap each other without physically touching each other in a depth direction of the substrate in a state where a region for separating the at least parts of the charge holding portions and the floating diffusion layers is provided therebetween.
