  • Patent number: 11830840
    Abstract: An integrated circuit chip includes a substrate on which a standard cell is disposed. The integrated circuit chip includes a plurality of power bumps including a plurality of first power bumps and a plurality of second power bumps, the plurality of power bumps. disposed to have a staggered arrangement in a central region of one surface of the integrated circuit chip, and connected to provide power to the standard cell; a first metal wiring disposed below the plurality of first power bumps and electrically connected to the plurality of first power bumps, at least a part of the first metal wiring overlapping the plurality of first power bumps from a plan view; and a second metal wiring horizontally separated from the first metal wiring, disposed below the plurality of second power bumps, and electrically connected to the plurality of second power bumps, at least a part of the second metal wiring overlapping the plurality of second power bumps from the plan view.

  • Patent number: 11728300
    Abstract: A semiconductor device includes a semiconductor substrate, an integrated device ort the semiconductor substrate, a first redistribution layer on the semiconductor substrate, the first redistribution layer having first conductive patterns electrically connected to the integrated device, a second redistribution layer on the first redistribution layer, the second redistribution layer having second conductive patterns connected to the first conductive patterns, and third conductive patterns on a top surface of the second redistribution layer. The third conductive patterns include pads connected to the second conductive patterns, under-bump pads spaced apart from the pads, a grouping pattern between the pads and an outer edge of the second redistribution layer, and wiring lines that connect the under-bump pads to the pads and connect the pads to the grouping pattern.

  • Patent number: 9430648
    Abstract: A method of updating firmware of a near field communication (NFC) device includes copying metadata, which is included in a firmware image file, from an application processor to the NFC device. One of a certification success signal and a certification fail signal is provided from the NFC device to the application processor after the NFC device verifies an integrity of the metadata. Firmware data, which is included in the firmware image file, is copied from the application processor to the NFC device when the application processor receives the certification success signal from the NFC device.
