  • Patent number: 10446492
    Abstract: Disclosed herein is a configuration for ensuring sufficient power supply ability and ESD protection capability for I/O cells in a semiconductor integrated circuit device, without increasing its circuit area. In two I/O cell rows, a pair of I/O cells for supplying a power supply potential or ground potential are connected together via a common power supply interconnect. The I/O cells are arranged so as to overlap with each other in a first direction in which the I/O cells are arranged. The common power supply interconnect extends in a second direction perpendicular to the first direction, and is connected to first pads that are located closest in the first direction to the common power supply interconnect.

  • Publication number: 20090019412
    Abstract: According to the present invention, timing information, connection information and physical information are received, and at the weighting determination step, the degree to which a cell can move is weighted. Then, at the movement range determination step, the movement enabled range of the cell is determined, and whether or not a cell placement area is available is decided. When it is decided that a cell placement area is available, the processing advances either to the cell movement area extension step or to the cell placement area acquisition step. Thereafter, an automatic, optimal placement process is performed for the cell.

  • Publication number: 20070129077
    Abstract: The present invention relates to a mobile communication system in which variable bandwidths are set in this manner, and a base station controller for setting these variable bandwidths. A base station controller sends a value indicating a requested bandwidth required for a channel of variable bandwidth to a base station. The base station, upon receiving the request, returns a response of an allocatable bandwidth equal to or lower than the requested bandwidth, to the base station controller. The base station controller, upon receiving the response, sets the channel of variable bandwidth between a mobile station and the base station, and between the base station and the base station controller, according to the allocatable bandwidth.

  • Patent number: 6448148
    Abstract: A water solution of lead nitrate is infiltrated into a substrate made of a porous material, and liquid drops of a water solution of sodium sulfide, which is charged into a ink cartridge of a minute nozzle, are sprayed onto the substrate from the minute nozzle. The lead component from the lead nitrate water solution and the sulfur component from the sodium sulfide water solution are synthesized directly on the substrate, and thus, a thin film made of lead sulfide is formed on the substrate.
