Publication number: 20240128296Abstract: The present application discloses a double-layer stacked CMOS image sensor, photo diode and transfer gate transistor of a pixel cell are formed on the first substrate sequentially along a longitudinal direction, and the other pixel transistors of the pixel cell are formed on the second substrate. The first substrate and the second substrate are packaged separately, and the second substrate is stacked on the top side of the first substrate instead of being in juxtaposition. Since the photo diode and the pixel transistors other than the transfer gate transistor of the pixel cell are located on two separate substrates respectively, the area of a photo diode region may be increased significantly, thereby greatly increasing full well capacitance of the image sensor and increasing a dynamic range, and reduce a dark current and image noise significantly, thereby improving the dark line noise and full well capacitance simultaneously.Type: ApplicationFiled: August 14, 2023Publication date: April 18, 2024Applicant: Shanghai Huali Microelectronics CorporationInventors: Xing FANG, Chenchen QIU, Jun QIAN, Chang SUN, Zhengying WEI
