Abstract
In the case where a signal delay is found in a circuit operation in a semiconductor chip, when a repeater for delay reduction is additionally formed as a result of a design change, an increase in the area of the semiconductor chip and an increase in the manufacturing cost of a semiconductor device are prevented. The inverter forming the repeater is formed of transistors formed in the upper portion of stacked wiring layers, not transistors in the vicinity of a main surface of a semiconductor substrate. By thus implementing a design change such that the repeater is added, the number of the wiring layers which need a layout change is reduced.
