摘要

A potential-supply connection interconnect is provided in a multilayer interconnect layer. The potential supply connection interconnect overlaps some cell of I/O cells in the outer peripheral cell column and some cell of I/O cells in the inner peripheral cell column in a plan view. The potential-supply connection interconnect connects a power potential supply interconnect located below the outer peripheral cell column to a power potential supply interconnect located below the inner peripheral cell column and also connects a ground potential supply interconnect located below the outer peripheral cell column to a ground potential supply interconnect located below the inner peripheral cell column.
