  • Publication number: 20240290810
    Abstract: Various embodiments of the present disclosure are directed towards an image sensor comprising a pixel with a dual-PD layout for enhanced scaling down. The pixel spans a first integrated circuit (IC) die and a second IC die stacked with the first IC die. The pixel comprises a plurality of photodetectors in the first IC die, and further comprises a plurality of pixel transistors split amongst the first IC die and the second IC die. The plurality of photodetectors are grouped into one or more pairs, each having the dual-PD layout. A DTI structure completely and individually surrounds the plurality of photodetectors, and further extends completely through a substrate within which the plurality of photodetectors are arranged. As such, the DTI structure completely separates the plurality of photodetectors from each other.

  • Publication number: 20230362709
    Abstract: A method of deriving packet filter component of derived QoS rule and evaluating of packet when there are multiple C-TAGs and/or S-TAGs in Ethernet frame header is proposed. In one novel aspect, for a derived QoS rule, when a DL packet carries multiple C-TAGs or S-TAGs, the UE derives packet filter component of the QoS rule derived from the outermost C-TAG and/or the outermost S-TAG of the DL packet. In another novel aspect, when evaluating a data packet carrying multiple C-TAGs or S-TAGs, the UE/NW evaluates the outermost C-TAG and/or the outermost S-TAG of the data packet, the UE/NW then send the data packet on the corresponding QoS rule of the matched packet filter.

  • Patent number: 9543355
    Abstract: A method of fabricating a semiconductor image sensor device is disclosed. A plurality of radiation-sensing regions is formed in a substrate. The radiation-sensing regions are formed in a non-scribe-line region of the image sensor device. An opening is formed in a scribe-line region of the image sensor device by etching the substrate in the scribe-line region. A portion of the substrate remains in the scribe-line region after the etching. The opening is then filled with an organic material.

  • Patent number: 8815723
    Abstract: A method of forming an image sensor device includes forming a light sensing region at a front surface of a silicon substrate and a patterned metal layer there over. Thereafter, the method also includes performing an ion implantation process to the back surface of the silicon substrate and performing a green laser annealing process to the implanted back surface of the silicon substrate. The green laser annealing process uses an annealing temperature greater than or equal to about 1100° C. for a duration of about 100 to about 400 nsec. After performing the green laser annealing process, a silicon polishing process is performed on the back surface of the silicon substrate.
