ABSTRACT:
A semiconductor integrated circuit device is disclosed which comprises a plurality of cell rows each including a plurality of standard cells, signal connection cells provided one at each of the cell rows and located on one straight line across that cell row array, a line for connection cells which is connected to the signal connection cell and adapted to supply a signal which is propagated via the signal connection cell to the cell in the corresponding cell row, and cell-to-cell connection lines each connecting the signal connection cells together and having a broader connection width than that of an ordinary connection line. In the semiconductor integrated circuit device of the present invention the respective signal connection cells are connected together by the cell-to-cell connection line having a broader connection width than that of the ordinary connection line, so that a signal is propagated to the respective cell row in a low-resistance way. The respective signal connection cells are each arranged at the respective cell row in a manner to be located on a single straight line to achieve the reduction of a distance between the signal connection lines. Since a signal coming from the signal connection cell at each cell row is supplied in a row unit to the associated cell in the respective cell row via the connection line for cell rows, a signal propagation over a minimum connection line length is assured.
