Defect diagnosis based on DFM guidelines

Following design-for-manufacturability (DFM) guidelines during chip design can lower the possibility of occurrence of systematic defects. In this paper, we investigate the use of DFM guidelines during the defect diagnosis process with the goal of identifying which DFM guidelines are responsible for the defects present in failing chips. We also introduce a new metric called diagnostic coefficient that allows us to rank the guidelines according to their contribution of hard-to-diagnose defects. DFM guidelines that are ranked high should be applied during chip design in order to obtain chips that are easier to diagnose.
