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

Patent number: 12282592Abstract: A method for detecting full-body gestures by a mobile device includes a host mobile device detecting the tracked body of a co-located participant in a multi-party session. When the participant's tracked body provides a full-body gesture, the host's mobile device recognizes that there is a tracked body providing a full-body gesture. The host mobile device iterates through the list of participants in the multi-party session and finds the closest participant mobile device with respect to the screen-space position of the head of the gesturing participant. The host mobile device then obtains the user ID of the closest participant mobile device and broadcasts the recognized full-body gesture event to all co-located participants in the multi-party session, along with the obtained user ID. Each participant's mobile device may then handle the gesture event as appropriate for the multi-party session. For example, a character or costume may be assigned to a gesturing participant.Type: GrantFiled: September 1, 2022Date of Patent: April 22, 2025Assignee: Snap Inc.Inventors: Daekun Kim, Lei Zhang, Youjean Cho, Ava Robinson, Yu Jiang Tham, Rajan Vaish, Andrés Monroy-Hernández
