  • Patent number: 9997552
    Abstract: The present technology relates to a solid-state imaging device, an imaging apparatus, an electronic apparatus, and a semiconductor device, which can prevent overflow of an underfilling resin filled in a portion adapted to connect the substrate to the flip chip and can prevent secondary damages such as electric short-circuit and contact with processing equipment. By utilizing a molding technology of forming an on-chip lens, a dam is formed in a ring shape or a square shape in a manner surrounding a range where a flip chip is connected via a solder bump on an upper layer of a substrate of the solid-state imaging device and provided in order to form the on-chip lens. This can block the underfilling resin filled in the range where the substrate and the flip chip are electrically connected. The present technology can be applied to a solid-state imaging device.

  • Patent number: 7016636
    Abstract: In a double-sided image forming apparatus and method, back-side images are developed on a first middle transfer belt prior to developing of front-side images on the first middle transfer belt, and the back-side images are transferred to a second middle transfer belt. The number of back-side images allowed to be supported at a time on the second middle transfer belt is determined. The number of back-side images are developed on the first middle transfer belt prior to developing of the same number of front-side images on the first middle transfer belt. The front-side image of the first middle transfer belt and the back-side image of the second middle transfer belt are simultaneously formed on both sides of a copy sheet.
