  • Publication number: 20260130280
    Abstract: A stacked package device has a first package and a second package vertically stacked and electrically connected to each other. One or each of the first package and the second package includes a first substrate, a second substrate and an intermediate substrate. A first flip-chip and a second flip-chip are respectively mounted on opposite surfaces of the first substrate and the second substrate. The intermediate substrate is electrically connected between the opposite surfaces of the first substrate and the second substrate for signal transmission between the first flip-chip and the second flip-chip. The use of the intermediate substrate avoids the structure damage resulting from thermal stress. Since no encapsulant is provided to cover each flip-chip, the problem of separation between the encapsulant and the substrates is avoided.

  • Patent number: 12507495
    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.

  • Patent number: 12506101
    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.
