Pattern for Electrical Assessment of Images Formed in Conductive Films

A test pattern is described which enables sensitive electrical assessment of the success with which images are formed in electric ally conductive thin films. By measuring electrical resistance of the pattern with a four point probe, small shifts from nominal dimensions caused by variations in a photoetching process are readily detected.
