Abstract
At least one method, apparatus and system disclosed involves providing an integrated circuit having metal feature flyover over an middle-of-line (MOL) feature. A first location for a non-contact intersection region between a first middle of line (MOL) interconnect feature and a metal feature in a functional cell is determined. A dielectric feature is formed over the first MOL interconnect feature at the first location. The metal feature is formed over the dielectric layer, the dielectric layer providing a predetermined amount of voltage isolation between the first MOL interconnect feature and the metal feature.
