  • Integrated circuit containing standard logic cells and library-compatible, NCEM-enabled fill cells, including at least via-open-configured, GATE-short-configured, GATECNT-short-configured, and metal-short-configured, NCEM-enabled fill cells
    Patent number: 9691672
    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 GATE-short-related failure mode, one GATECNT-short-related failure mode, and one metal-short-related failure mode.

  • Integrated Circuit Containing DOEs of NCEM-enabled Fill Cells
    Publication number: 20170178981
    Abstract: Wafers, chips, or dies that contain fill cells with structures configured to obtain in-line data via non-contact electrical measurements (“NCEM”). Such NCEM-enabled fill cells may target/expose a variety of open-circuit, short-circuit, leakage, or excessive resistance failure modes. Such wafers, chips, or dies may include Designs of Experiments (“DOEs”), comprised of multiple NCEM-enabled fill cells, in at least two variants, all targeted to the same failure mode(s).

    Publication number: 20150270181
    Abstract: Product ICs/wafers include additional diagnostic, test, or monitoring structures opportunistically placed in filler cell positions, within tap cells, within decap cells, within scribe line areas, and/or within dummy fill regions. Improved fabrication processes utilize data from such structure(s) in wafer disposition decisions, rework decisions, process control, yield learning, or fault diagnosis.
