Abstract
A method of forming a semiconductor device can comprise providing a first shift region in which to determine a first displacement. A second shift region may be provided in which to determine a second displacement. A unique electrically conductive structure may be formed comprising traces to account for the first displacement and the second displacement. The electrically conductive structure may comprise traces comprising a first portion within the first shift region and a second portion of traces in the second shift region laterally offset from the first portion of traces. A third portion of the traces may be provided in the routing area between the first shift region and the second shift region. A unique variable metal fill may be formed within the fill area. The variable metal fill may be electrically isolated from the unique electrically conductive structure.
