Abstract:
1. A semiconductor integrated circuit device comprising: a power supply main line for supplying a power supply voltage; a plurality of power supply lines connected to said power supply main line; at least one capacitor cell disposed between said power supply lines; at least one logic cell disposed between said power supply lines, said logic cell configuring a semiconductor integrated circuit, wherein said capacitor cell is placed between said power supply main line and said logic Cell; and a ground main line connected to a ground potential, said ground main line being substantially parallel to said power supply main line; and a plurality of ground lines connected to said ground main line, said ground lines being substantially parallel to said power supply lines; wherein said capacitor cell is placed between said ground main line and said logic cell, and wherein a distribution density of said capacitor cell increases as said capacitor cell is separated from said power supply main line.
