  • Publication number: 20110156188
    Abstract: An image sensor packaging structure with a low transmittance encapsulant is provided. The image sensor packaging structure includes a substrate, a chip, a transparent lid, and the low transmittance encapsulant. The chip is combined with the substrate. The transparent lid is adhered to the chip and cover above a sensitization area of the chip to form an air cavity. The low transmittance encapsulant is formed on the substrate and encapsulates the chip and the transparent lid so as to accomplish the package of the image sensor packaging structure. Due to the feature of prohibiting from light passing through the low transmittance encapsulant, the arrangement of the low transmittance encapsulant can avoid the light from outside interfere the image sensing effect of the image sensor. Therefore, the quality of the image sensing can be ensured.

  • Publication number: 20110156187
    Abstract: An image sensor packaging structure with a predetermined focal length is provided. The image sensor packaging structure includes a substrate, a chip, an optical assembly, and an encapsulation compound. The chip has a sensitization area and is coupled to the substrate. Conductive contacts on the substrate are electrically connected with conductive contacts around the sensitization area. The optical assembly has the predetermined focal length and is disposed above the chip so as to form an air cavity between the optical assembly and the sensitization area of the chip. The encapsulation compound is formed on the substrate to surround the chip and the optical assembly. With the above stated structure, not only can the focus adjusting procedure be dispensed with, but also the image sensor packaging structure can be manufactured by a molding or dispensing process.

  • Publication number: 20110024862
    Abstract: The present invention discloses an image sensor package structure with a large air cavity. The image sensor package structure includes a substrate, a chip, a cover and a package material. The chip is combined with the substrate. A plastic sheet of the cover is adhered to the chip and a transparent lid of the cover is combined with the plastic sheet to provide a covering over a sensitization area of the chip so as to form an air cavity. The package material is arranged on the substrate and encapsulated around the chip and the cover. The plastic sheet having a predetermined thickness can increase the distance between the transparent lid and the chip to enlarge the air cavity. Thus, the image-sensing effect of the image sensor package structure can be improved and the ghost image problem resulting from multi-refraction and multi-reflection of light can be minimized.

  • Publication number: 20110024610
    Abstract: The present invention discloses an image sensor package structure. The image sensor package structure includes a substrate, a chip, a transparent lid, a first casing and a package material. The transparent lid covers a sensitization area of the chip and it also adheres to the chip which is deposed on the substrate. The first casing, which adheres to the transparent lid, forms an opening so that light can pass through the opening and the transparent lid to enter into the sensitization area. The package material covers around the chip and the transparent lid and fills between the substrate and the first casing. Because of the arrangement of adhesive layers placed between the first casing and the transparent lid and between the transparent lid and the chip, the blockage area from moisture is elongated. Therefore, the reliability of the image sensor package structure can be enhanced.
