State of the art Integrated Circuits (ICs) encompass a variety of circuits, which have a wide variety of contact densities as measured in regions from 10 to 1000 microns in size. Fabrication processes for contacts have difficulty with high and low contact densities on the same IC, leading to a high incidence of electrical shorts and reduced operating speed of the circuits. This problem is expected to worsen as feature sizes shrink in future technology nodes. This invention is an electrically non-functional contact, known as a dummy contact, that is utilized to attain a more uniform distribution of contacts across an IC, which allows contact fabrication processes to produce ICs with fewer defects, and a method for forming said dummy contacts in ICs.
