ABSTRACT:
In a substrate power supply cell, a portion of a substrate power supply wiring is exposed by forming a power supply wiring in a U-shape, and a connection portion to an upper-layer wiring is provided at a boundary portion of the substrate power supply cell. Thereby, a leakage current is reduced without a decrease in signal wiring efficiency.
