    Abstract: An image sensor package includes an image sensor chip having a chip body, a metal dam, and a transparent substrate having a surface. The chip body has an active surface including a photosensitive area and a non-sensitive area surrounding the photosensitive area. The metal dam is formed on the non-sensitive area of the active surface, surrounds a photosensitive layer formed on the photosensitive area at intervals, is electrically insulated from the chip body, and has a thickness. A glue dam is formed on the surface and is aligned with and is bonded to the metal dam. A thickness of the glue dam is less than the thickness of the metal dam. Accordingly, the metal dam and the glue dam are combined to form a dam structure, and the quantity of liquid glue to form the glue dam is decreased. Thus, the yield of the image sensor package is enhanced.

  • Publication number: 20240021637
    Abstract: An image sensor package with low light-sensing noise has a chip body having a photosensitive area and non-sensitive area. The photosensitive area includes a photosensitive layer having a plurality of photosensitive units. A color filter is disposed on the photosensitive layer and has a plurality of filter units corresponding to the photosensitive units and a black matrix. A black adhesive layer is disposed on the non-sensitive area for mounting a glass cover. A gap is kept between the glass cover and the first surface of the chip body. When an incident light passes through the glass cover and emits to the photosensitive area, the black matrix absorbs the light traveling through the filter unit toward the photosensitive units adjacent to the filter unit. Furthermore, a light emitting to the non-sensitive area can be absorbed by the black adhesive layer. Thus, a light-sensing noise of the chip can be effectively decreased.

  • Publication number: 20240021558
    Abstract: A chip structure has a chip body having a plurality of pads, a plurality of metal bumps respectively formed on the pads, and a patterned bump directly formed on the chip body. The patterned bump has at least two different upper and lower plane patterns. A top surface of each of the metal bumps is higher than a height position on which the upper plane pattern is. When the chip structure is ground to the height position, the ground tops of the metal bumps and the upper plane pattern are flush. Therefore, detecting whether the upper plane pattern is exposed determines whether all the metal bumps are exposed and flush to each other to avoid insufficient grinding depth or over-ground.
