  • Publication number: 20100187699
    Abstract: There is provided a layout structure of a semiconductor integrated circuit capable of preventing the thinning of a metal wiring line close to a cell boundary and wire breakage therein without involving increases in the amount of data for OPC correction and OPC process time. In a region interposed between a power supply line and a ground line each placed to extend in a first direction, first and second cells each having a transistor and an intra-cell line each for implementing a circuit function are placed to be adjacent to each other in the first direction. In a boundary portion between the first and second cells, a metal wiring line extending in a second direction orthogonal to the first direction is placed so as not to short-circuit the power supply line and the ground line.

  • Publication number: 20090166883
    Abstract: In a semiconductor integrated circuit including a plurality of cells, a supplementary power-supply wire is disposed between a lattice-shaped upper power-supply wire and a lower cell power-supply wire for cases in which power is supplied from the upper power-supply wire to the lower cell power-supply wire. The supplementary power-supply wire and the lower cell power-supply wire are connected by two vias. The supplementary power-supply wire and the upper power-supply wire are connected by a single via. Current from the supplementary power-supply wire is divided by the two vias and then supplied to the lower cell power-supply wire. Therefore, when power is supplied from the upper power-supply wire to the lower cell power-supply wire, current concentration at the connection points of the lower cell power-supply wire to the vias is decreased, thereby reducing wire breaks caused by EM (electro migration).

  • Publication number: 20080169487
    Abstract: In a layout structure of a semiconductor integrated circuit, when transistors are arranged in a constant gate wiring pitch, a common source diffusion region is provided between two adjacent transistors, a CA via is provided on the common source diffusion region, and a source wiring connected to the CA via is provided on the common source diffusion region. An inter-drain wiring connecting the drain regions of the two transistors is formed in a wiring layer higher than the source wiring. Therefore, the wiring path of the source wiring is not limited by the wiring path of the inter-drain wiring, and can be provided, covering the common source diffusion region to a further extent. As a result, the number of high-resistance CA vias or the flexibility of arrangement is increased, leading to a reduction in source resistance, resulting in an increase in operating speed of the semiconductor integrated circuit.
