摘要： An IC includes first and second designs of experiments (DOEs), each comprised of at least two fill cells. The fill cells contain structures configured to obtain in-line data via non-contact electrical measurements (“NCEM”). The first DOE contains fill cells configured to enable non-contact (NC) detection of snake opens, and the second DOE contains fill cells configured to enable NC detection of metal island opens.

摘要： An IC includes first and second designs of experiments (DOES), each comprised of at least two fill cells. The fill cells contain structures configured to obtain in-line data via non-contact electrical measurements (“NCEM”). The first DOE contains fill cells configured to enable non-contact (NC) detection of side-to-side shorts, and the second DOE contains fill cells configured to enable NC detection of tip-to-side shorts.

摘要： 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 AACNT-short-related failure mode, one TS-short-related failure mode, and one metal-short-related failure mode.
