  • Patent number: 7972890
    Abstract: Example embodiments may provide methods of manufacturing an image sensor. Example methods of manufacturing an image sensor may include forming a photoelectric converter in a semiconductor substrate, forming an interlayer insulating film covering a surface of the semiconductor substrate, forming metal wires and an inter-metal insulating film filling between the metal wires on the interlayer insulating film, forming openings above the photoelectric converter by removing a part of the inter-metal insulating film and the interlayer insulating film, curing the surface above the photoelectric converter by irradiating light into the openings, and/or forming a light transmitter filling the openings.

  • Patent number: 7402889
    Abstract: Disclosed is a metal-insulator-metal (MIM) capacitor structure formed by a metal interconnection process of trench-exposed metal layers formed on stacked interlayer insulating layers. The MIM capacitor uses a conductive layer conformally formed on the metal interconnection and/or trench regions to enlarge constituent electrode surface areas.
