Publication number: 20250151424Abstract: This application discloses a CIS pixel readout structure. An SF and an SG adopt an asymmetric spacer structure, so that the pitch from a lower end of a source metal plug of the SG to SG gate poly can be reduced while keeping the pitch from a lower end of a drain metal plug of the SF to SF gate poly unchanged, thus reducing the pitch from a drain connecting point of the SF to a source connecting point of the SG. Since a source of the SG is not connected with working voltage and it is not influenced by leakage, not only can GIDL current be maintained, but also parasitic resistance can be reduced. Without changing its effective size, it can reduce the parasitic resistance effect while reducing the area of a combined structure of the SF and the SG.Type: ApplicationFiled: July 24, 2024Publication date: May 8, 2025Applicant: Shanghai Huali Integrated Circuit CorporationInventors: Qiwei WANG, Zhen Gu, Haoyu Chen, Lei Zhang, Zhi Tian
