Abstract:
An IC includes logic cells, selected from a standard cell library, and fill cells, configured for compatibility with the standard logic cells. The fill cells contain structures configured to obtain in-line data via non-contact electrical measurements (“NCEM”). The IC includes such NCEM-enabled fill cells configured to enable detection and/or measurement of a variety of open-circuit and short-circuit failure modes, including at least one via-open-related failure mode, one GATECNT-short-related failure mode, one metal-short-related failure mode, and one AA-short-related failure mode.
