IMAGE SENSOR AND ELECTRONIC DEVICE INCLUDING THE SAME - A simplified explanation of the abstract
This abstract first appeared for US patent application 18140324 titled 'IMAGE SENSOR AND ELECTRONIC DEVICE INCLUDING THE SAME
Simplified Explanation
- The patent application describes an image sensor and electronic devices that use this image sensor. - The image sensor includes a shared pixel with four subpixels that share a floating diffusion (FD) region. - The image sensor also includes multiple unit pixels arranged around the FD region, with deep trench isolation separating them. - Each unit pixel has a first transfer transistor next to the FD region, a reset transistor in the first unit pixel, and a source follower transistor in the second unit pixel. - The FD region is connected to the reset transistor's source region and the source follower transistor's gate through a metal wiring.
Original Abstract Submitted
The present disclosure provides image sensor and electronic devices including image sensors. In some embodiments, the image sensor includes a shared pixel including four subpixels that have a 2×2 structure sharing a floating diffusion (FD) region, a plurality of unit pixels surrounding the FD region and arranged apart from one another through a deep trench isolation, a first transfer transistor disposed adjacent to the FD region in each of the plurality of unit pixels, a reset transistor provided in a first unit pixel of the plurality of unit pixels and disposed at an outer portion of the shared pixel, and a source follower transistor provided in a second unit pixel and disposed at the outer portion of the shared pixel. The FD region is coupled, through a metal wiring, to a source region of the reset transistor and a gate of the source follower transistor.
