  • Patent number: 9554024
    Abstract: An image sensor module and an imaging device. An image sensor package includes a plurality of image sensor chips for generating image signals and a lower transparent board over the image sensor chips. An upper transparent board is positioned over the lower transparent board and includes a lens for focusing an external light to the image sensor chips. An adhesion member is interposed between the upper transparent board and the lower transparent board, and thus the upper and lower transparent boards are adhered to each other by the adhesion member such that the lens and the image sensor chips are aligned with each other. A dehumidifying agent is arranged in the adhesion member to absorb moistures from an interior of the image sensor module. Accordingly, the moistures are prevented from being condensed onto the surface of the image sensor module.

  • Patent number: 8125042
    Abstract: Provided are a semiconductor package and a method of manufacturing the same. The semiconductor package includes a semiconductor chip, a transparent substrate, an adhesive pattern, and at least one dew-proofer. The semiconductor includes a pixel area. The transparent substrate is disposed on the semiconductor chip. The adhesive pattern is disposed between the semiconductor chip and the transparent substrate and provides a space on the pixel area. At least one dew-proofer is disposed between the semiconductor chip and the transparent substrate and spaced from the adhesive pattern.
