  • Patent number: 11962923
    Abstract: An image processing device includes a target pixel detector configured to detect a plurality of target pixels in which noise is generated among a plurality of pixels included in an image sensor. The image processing device also includes a target pixel corrector configured to change target pixel values, which are pixel values of the plurality of target pixels, by using average pixel values of neighboring pixels included in a preset range based on a position of each of the plurality of target pixels. The image processing device further includes a target pixel compensator configured to compensate for the target pixel values by using an accumulation value obtained by accumulating values corresponding to a decimal fraction part of the average pixel values.

  • Patent number: 9852256
    Abstract: A method for manufacturing a semiconductor device can reduce congestion across wires while reducing a wire length. The method includes determining a first TSV candidate region in a first die and determining a second TSV candidate region in a second die parallel to the first die. The method also includes determining a first bound region. The first bound region includes a horizontal location of a first pin of the first die and a horizontal location of a second pin of the second die. The method additionally includes calculating an area from overlapped regions between the first bound region and each of the first TSV candidate region and the second TSV candidate region, and performing routing for connecting the first pin and the second pin to each other based on the calculated area.

  • Patent number: 9135390
    Abstract: To design a power supply network of a 3D semiconductor device employing through-silicon-via (TSV) technology, board wiring of each of boards of the device is determined. An initial network structure is created for the boards. A layout of power bumps and through-silicon-vias, using the initial network structure, is produced such that voltages of all nodes of wiring of the boards are greater than a reference voltage. A semiconductor device having boards, power bumps and through-silicon-vias conforming to the layout is fabricated. Thus, the numbers of the through-silicon-vias and the power bumps of the power supply network of the semiconductor device are minimal.
