摘要： A standard cell semiconductor integrated circuit device design provides a standard cell semiconductor device that includes first standard cells and user-defined target standard cells which consume more power or include other operational characteristics that differ from the operational characteristics of the first standard cells. The standard cells are routed to ground and power wires using one power rail and the target cells are routed to the ground and power lines using the first power rail and a second power rail to alleviate electromigration in either of the power rails. The two power rails include an upper power rail and a lower power rail. An intermediate conductive layer may be disposed between the upper and lower power rails to provide for signal routing by lateral interconnection between cells.
