  • Publication number: 20230343803
    Abstract: The present technology relates to a semiconductor device that includes an underfill resin and a light-shielding resin and allows to achieve a decrease in device size, a method of producing the same, and an electronic apparatus. The semiconductor device includes: a substrate having a pixel region in which a plurality of pixels is arranged; and one or more chips flip-chip bonded to the substrate via a connection terminal. A material of a first resin that protects a back surface of the chip and a material of a second resin that protects a side surface of the chip are different from each other. The present technology is applicable to, for example, a semiconductor device in which an image sensor chip and a signal processing chip are flip-chip bonded to each other.

  • Publication number: 20230179846
    Abstract: The present disclosure relates to a camera module capable of achieving a smaller height, a method of manufacturing a camera module, an imaging apparatus, and an electronic apparatus. An imaging device having its imaging surface bonded to a provisional substrate is attached, and the imaging device in that state is joined to a substrate via an electrode having a TSV structure. After the provisional substrate is detached, an IR cut filter (IRCF) on which a light blocking film is printed or jet-dispensed in a region other than the effective pixel region is bonded to the imaging surface via a transparent resin. Because of this, there is no need to provide any sealing glass in the stage before the imaging surface, and the optical length of the lens can be shortened. Thus, a smaller height can be achieved. The present disclosure can be applied to camera modules.
