Abstract
A semiconductor integrated circuit is provided that achieves a lesser degree of inconsistency in the delay time of clock signals that are internally provided. An input clock signal distributed via an input clock supply path is provided to individual timing adjustments circuits. The timing adjustment circuits are each constituted by providing a wiring pattern having serial resistors and gaps in a circuit correction area. The wiring pattern of the semiconductor integrated circuit is corrected by employing a focused ion beam apparatus to achieve an adjustment so that internal input clock signals at the same phase are obtained from the individual timing adjustment circuits. Using the wiring pattern having undergone the adjustment, a semiconductor integrated circuit is manufactured as a product.
