  • Patent number: 12191327
    Abstract: The present disclosure relates to a CMOS image sensor, and an associated method of formation. In some embodiments, the CMOS image sensor comprises a substrate and a transfer gate disposed from a front-side surface of the substrate. The CMOS image sensor further comprises a photo detecting column disposed at one side of the transfer gate within the substrate. The photo detecting column comprises a doped sensing layer comprising one or more recessed portions along a circumference of the doped sensing layer in parallel to the front-side surface of the substrate. By forming the photo detecting column with recessed portions, a junction interface is enlarged compared to a previous p-n junction interface without recessed portions, and thus a full well capacity of the photodiode structure is improved.

  • Patent number: 12191282
    Abstract: Various embodiments of the present disclosure are directed towards a shared frontside pad/bridge layout for a three-dimensional (3D) integrated circuit (IC), as well as the 3D IC and a method for forming the 3D IC. A second IC die underlies the first IC die, and a third IC die underlies the second IC die. A first-die backside pad, a second-die backside pad, and a third die backside pad are in a row extending in a dimension and overlie the first, second, and third IC dies. Further, the first-die, second-die, and third-die backside pads are electrically coupled respectively to individual semiconductor devices of the first, second, and third IC dies. The second and third IC dies include individual pad/bridge structures at top metal (TM) layers of corresponding interconnect structures. The pad/bridge structures share the shared frontside pad/bridge layout and provide lateral routing in the dimension for the aforementioned electrical coupling.

  • Patent number: 12157267
    Abstract: A large area deposition type additive manufacturing equipment is disclosed. The large area deposition type additive manufacturing equipment includes a light source module, a dynamic photomask module, a raw material tank and a deposition module. The light source module includes a plurality of light emitting members, a light diffusion member, a light enhancement member and a light emitting angle limiter. Light emitted from the light emitting members passes through the light diffusion member, the light enhancement member and the light emitting angle limiter to become a collimated curing light. The collimated curing light travels through a transparent member of the raw material tank and a dynamic photomask module to reach liquid photocurable material in the raw material tank, thereby curing the liquid photocurable material. The angle of emitted light ranges within ±30° with respect to a normal line of an incident plane of the light source module.
