ABSTRACT:
A semiconductor integrated circuit device comprising a plurality of rows of logic cells, the rows of logic cells being spaced apart from each other to define channel areas therebetween, the logic cells being arranged to form a plurality of function blocks each having a predetermined logic function, and at least one wiring layer overlying the rows of logic cells and the channel areas, the wiring layer comprising a plurality of inter-cell wiring areas extending along the rows of logic cells and including interconnects between desired ones of the logic cells and inter-block wiring areas extending along the channel areas and including interconnects between desired ones of the function blocks. Each of the inter-cell wiring areas comprises wiring sections respectively associated with the function blocks and mostly consisting of wiring sections having widths within a predetermined range.
