  • Publication number: 20230215830
    Abstract: When a semiconductor element and a wiring board are connected to each other, connection at a minute pitch is performed while securing reliability. In a semiconductor device, a semiconductor element and a wiring board are connected to each other. A bump is formed on an electrode in either the semiconductor element or the wiring board. This bump contains metal nanoparticles as a component. The bump may be formed by sintering the metal nanoparticles that are applied. Furthermore, the metal nanoparticles may be applied and sintered a plurality of times to form a plurality of layers. A connection between the semiconductor element and the wiring board may be formed by sintering the other metal nanoparticles that are applied.

  • Publication number: 20220415937
    Abstract: Alignment accuracy between an imaging element and a filming lens is improved. An imaging apparatus includes an imaging element, a wiring substrate, a sealing section, and fitting sections. The imaging element includes an imaging chip and pads. A light transmission section that transmits incident light is arranged on the imaging chip, and the imaging chip generates an image signal on the basis of the incident light that has transmitted through the light transmission section. The pads are arranged on a bottom surface of the imaging chip which is a surface different from the surface on which the light transmission section is arranged and convey the generated image signal. The wiring substrate includes wiring that is connected to the pads, and the imaging element is arranged on a front surface of the wiring substrate. The sealing section is arranged adjacent to side surfaces of the imaging chip which are the surfaces adjacent to the bottom surface of the imaging chip and seals the imaging chip.

  • Patent number: 7367120
    Abstract: A method of manufacturing a solid-state imaging device. An end portion on the aperture side of each of the plurality of wirings forms an internal terminal portion and an end portion on the outer peripheral side of each of the plurality of wirings forms an external terminal portion, the internal terminal portion of the wiring being connected electrically with an electrode of the imaging element. The wirings are made of thin metal plate leads, the base is made up of a resin molded member in which the thin metal plate leads are embedded, and at least a part of a side edge face of the thin metal plate leads is embedded in the base. The rigidity of the base is enhanced by the thin metal plate leads, thus reducing a curl and a warp of the base.
