    Abstract: A packaging substrate having a semiconductor chip embedded and a fabrication method thereof are provided. The method includes forming a semiconductor chip in a through cavity of a core board and exposing a photosensitive portion of the semiconductor chip from the through cavity; sequentially forming a first dielectric layer and a first circuit layer on the core board, the first circuit layer being electrically connected to the electrode pads of the semiconductor chip; forming a light-permeable window on the first dielectric layer to expose the photosensitive portion of the semiconductor chip and adhering a light-permeable layer onto the light-permeable window, thereby permitting light to penetrate through the light-permeable layer to reach the photosensitive portion. Therefore, when fabricated with the method, the packaging substrate dispenses with conductive wires and dams and thus can be downsized.

The dam is arranged on the top surface of the transparent lid and the inner surface of the mold can exactly contact with the top surface of dam so that the mold compound injected into the mold cavity is prevented from overflowing to the transparent lid by the dam. Furthermore, the arrangement of the dam and the mold compound can increase packaged areas and extend blockage to invasive moisture so as to enhance the reliability of the image sensor package structure.

  • 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.
