ABSTRACT:
An integrated circuit having a metal interconnect layer, and also having a conductive line and a boundary defined with a uniform distance from the conductive line that defines a “keep out” distance between the boundary and the conductive line. A set of first fill elements are uniformly arranged along the boundary outside of the “keep out” distance, and a set of second fill elements further from the conductive line than the first fill elements are arranged in a pattern that would be uniform, but for having some fill elements missing from the pattern.
