  • Patent number: 10734374
    Abstract: An area of a semiconductor device having a FINFET can be reduced. The drain regions of an n-channel FINFET and a p-channel FINFET are extracted by two second local interconnects from a second Y gird between a gate electrode and a dummy gate adjacent thereto, to a third Y grid adjacent to the second Y gird. These second local interconnects are connected by a first local interconnect extending in the X direction in the third Y grid. According to such a cell layout, although the number of grids is increased by one because of the arrangement of the first local interconnect, the length in the X direction can be reduced. As a result, the cell area of the unit cell can be reduced while a space between the first and second local interconnects is secured.

  • Patent number: 10074651
    Abstract: A semiconductor device is provided which suppresses variations in transistor characteristics such as a source-drain diffusion capacitance. A first transistor TRA is formed in a first element forming area EFA as a divided transistor. A second transistor TRB is formed in a second element forming area EFB as another divided transistor. The first element forming area EFA and the second element forming area EFB are set to the same size. The first element forming area EFA and the second element forming area EFB are arranged deviated from each other in an X direction by a length SPL corresponding to the minimum pitch PT of a gate wiring GH.

  • Patent number: 8264011
    Abstract: CMOS inverters are included in a standard cell. Power supply lines are electrically connected to CMOS inverters, and include lower layer interconnects and upper layer interconnect. Lower layer interconnects extend along a boundary of standard cells adjacent to each other and on the boundary. Upper layer interconnects are positioned more inside in standard cell than lower layer interconnects, as viewed from a plane. CMOS inverters are electrically connected through upper layer interconnects to lower layer interconnects. Thus, a semiconductor device is obtained that can achieve both higher speeds and higher integration.
