Patents by Inventor Chih-Yeh YU

Chih-Yeh YU has filed for patents to protect the following inventions. This listing includes patent applications that are pending as well as patents that have already been granted by the United States Patent and Trademark Office (USPTO).

  • Patent number: 11941338
    Abstract: Integrated circuits (IC) are provided. An IC includes a plurality of macros and a top channel. Each macro includes a macro boundary and a main pattern surrounded by the macro boundary. The top channel includes a plurality of first and second sub-channels. Each first sub-channel is arranged between a first macro and a second macro, and is formed by a plurality of first dummy boundary cells. Each second sub-channel is arranged between two of the second macros, and is formed by a plurality of second dummy boundary cells. The macro boundaries of the first macros are formed by the first dummy boundary cells, and the macro boundaries of the second macros are formed by the second dummy boundary cells. A first gate length of dummy patterns within the first dummy boundary cells is greater than a second gate length of dummy patterns within the second dummy boundary cells.

  • Patent number: 10177097
    Abstract: An integrated circuit (IC) structure includes a plurality of driver pins, each driver pin positioned at a driver pin level and oriented in a driver pin direction, and a plurality of layers of metal segment arrays. Each layer of metal segment arrays has a layer direction and includes two parallel metal segments oriented in the layer direction. The layer direction of a lowermost layer is perpendicular to the driver pin direction, the layer direction of each additional layer is perpendicular to the layer direction of a layer immediately below the additional layer, and each metal segment of a topmost layer is electrically connected to each driver pin of the plurality of driver pins.
