Semiconductor integrated circuit device having a clock network capable of transmitting an internal clock signal with a reduced skew

摘要

A clock driver formation region in which clock drivers are formed is disposed in a position overlapping, in a plan view, with a ring interconnection line and a mesh interconnection line extending over a semiconductor substrate region. An extra region dedicated to the clock driver formation region is not required, and the clock drivers are dispersed in a circuit device. Therefore, by adjusting drive capabilities of the clock drivers, a clock skew can be reduced, and electromagnetic noises during operation of the clock driver can be absorbed by interconnection lines at a higher layer.
