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

Publication number: 20250150735Abstract: This application discloses a CIS pixel readout circuit structure. An SG and an SF adopt different transverse thicknesses of spacers. The spacer of the SG adopts a smaller transverse thickness to reduce the parasitic resistance. The spacer of the SF adopts a larger transverse thickness to reduce the GIDL current. In the CIS pixel readout circuit structure according to this application, drain metal plugs are formed on outer sides of both left and right ends of an SF gate structure. The SF and the SG form a T-shaped combined compact structure to achieve equivalent parallel connection of two SF, thus effectively reducing the parasitic resistance of the share active area between the SG and the SF, and simultaneously saving the space area. This application further discloses a method for fabricating a CIS pixel readout circuit structure.Type: ApplicationFiled: August 20, 2024Publication date: May 8, 2025Applicant: Shanghai Huali Integrated Circuit CorporationInventors: Qiwei WANG, Zhen GU, Haoyu CHEN, Lei ZHANG, Zhi TIAN

Publication number: 20250142819Abstract: The present disclosure discloses a method for manufacturing a NOR flash. The drain area groove and the peripheral isolation grooves are first formed and filled with the trench isolation oxide, followed by the formation of the source area groove, and then the SiH4 layer is deposited. Due to the poor filling property of SiH4, the air gap may be formed at the source area groove with a small gap, and at this time, the drain area groove in the drain area of the storage area and the peripheral isolation groove in the logic area both have been filled and thus are unaffected. The method for manufacturing a NOR flash of the present disclosure allows the formation of the source air gap of the NOR flash based on a post-source preparation process and good filling of the drain, reducing the coupling effect between the source polysilicon gates.Type: ApplicationFiled: July 19, 2024Publication date: May 1, 2025Applicant: Shanghai Huali Integrated Circuit CorporationInventors: Qiwei WANG, Yufei SHU, Shaokang YAO, Zhi TIAN, Haoyu CHEN
