Patent number: 11955496Abstract: The present disclosure relates to an image sensor having a photodiode surrounded by a back-side deep trench isolation (BDTI) structure, and an associated method of formation. In some embodiments, a plurality of pixel regions is disposed within an image sensing die and respectively comprises a photodiode configured to convert radiation into an electrical signal. The photodiode comprises a photodiode doping column with a first doping type surrounded by a photodiode doping layer with a second doping type that is different than the first doping type. A BDTI structure is disposed between adjacent pixel regions and extending from the back-side of the image sensor die to a position within the photodiode doping layer. The BDTI structure comprises a doped liner with the second doping type and a dielectric fill layer. The doped liner lines a sidewall surface of the dielectric fill layer.Type: GrantFiled: September 29, 2020Date of Patent: April 9, 2024Assignee: Taiwan Semiconductor Manufacturing Company, Ltd.Inventors: Cheng-Ta Wu, Kuo-Hwa Tzeng, Yeur-Luen Tu

Patent number: 8061959Abstract: The present invention relates to a board inverter and a boarding inverting system. The board inverter includes a support, a first board picking device, an second board picking device and a controller. Each of the first board picking device and the second board picking device includes a driving mechanism and a first board picking device. The driving mechanism comprises a first linear driving means mounted on the support, a second linear driving means mechanically coupled to the first linear driving means, and a rotary driving means attached to the second linear driving means. The controller is connected to all the power supply members. The controller controls the motion of the first board picking device and the second board picking device such that the first board picking device and the second board picking device cooperatively inverting workpieces transmitted on a production line. The board inverter can be installed on a production line without altering the arrangement of existing production line.Type: GrantFiled: September 2, 2008Date of Patent: November 22, 2011Assignees: FuKui Precision Component (Shenzhen) Co., Ltd., Zhen Ding Technology Co., Ltd.Inventors: Ya-Ling Fan, Ching-Hung Pi, Cheng-Ta Tu, Chih-Yi Tu, Cheng-Hsien Lin
