Abstract:
1. A method of fabricating a passive element, the method comprising: forming the passive element and a dummy passive element adjacent to the passive element, wherein the dummy passive element substantially surrounds the passive element; forming a first dielectric layer over the passive element and the dummy passive element, wherein the first dielectric layer is substantially planar over an area between the passive element and the dummy passive element; wherein the first dielectric layer forming includes forming a step in the first dielectric layer above an outer edge of the dummy passive element; and forming a first interconnect to the passive element through the first dielectric layer and a dummy interconnect portion overlapping at least a portion of the dummy passive element, wherein the dummy interconnect portion forming includes forming an opening at the step in the first dielectric layer and depositing a conductive material into the opening to form the dummy interconnect portion.
