Abstract
A fill-placement method, according to which symmetrical fill patterns are used to insert fill tiles into one or more interconnect levels corresponding to symmetrical circuitry. The fill-placement method can be used, for example, in the fabrication of an integrated circuit having at least two complementary portions for which relatively tight circuit-matching requirements need to be met.
