  • Publication number: 20240147091
    Abstract: Imaging devices and electronic apparatuses incorporating imaging devices are provided. An imaging device as disclosed can include a first pixel of a first pixel and a second pixel of a second pixel. The first and second pixels each have a first electrode, a portion of a photoelectric conversion film, and a portion of a second electrode, where the photoelectric conversion film is between the first electrode and the second electrode. The first electrode of the first pixel has a first area, while the first electrode of the second pixel has a second area that is smaller than the first area. The first pixel can include a light shielding film. Alternatively or in addition, the first pixel can be divided into first and second portions.

  • Patent number: 8384185
    Abstract: A technique is provided which allows a chip mounted by wire bonding and a chip mounted by bump electrodes to share a manufacturing process. Both in a case where a chip is electrically coupled to an external circuit by bump electrodes and a case where the chip is electrically coupled to the external circuit by bonding wires, a bump coupling part and a bonding pad are both provided in a single uppermost wiring layer. When the bump electrodes are used, an opening is provided in an insulating film on the bump coupling part and a surface of the bonding pad is covered with the insulating film. On the other hand, when the bonding wires are used, an opening is provided in an insulating film on the bonding pad and a surface of the bump coupling part is covered with the insulating film.
