Abstract: An IC includes a contiguous standard cell area with first, second, and third TS-GATE-short-configured test area geometries disposed therein. In some embodiments, the contiguous standard cell area may further include: fourth and fifth TS-GATE-short-configured test area geometries, and/or other test area geometries, such as tip-to-tip-short, tip-to-side-short, diagonal-short, corner-short, interlayer-overlap-short, via-chamfer-short, merged-via-short, snake-open, stitch-open, via-open, or metal-island-open.

Abstract: Improved processes for manufacturing wafers, chips, or dies utilize in-line data obtained from non-contact electrical measurements (“NCEM”) of fill cells that contain structures configured target/expose a variety of open-circuit, short-circuit, leakage, or excessive resistance failure modes. Such processes may involve evaluating Designs of Experiments (“DOEs”), comprised of multiple NCEM-enabled fill cells, in at least two variants, all targeted to the same failure mode(s).

Abstract: A memory-specific implementation of a test and characterization vehicle utilizes a design layout that is a modified version of the product mask. Specific routing is used to modify the product mask in order to facilitate memory cell characterization. This approach can be applied to any memory architecture with word-line and bit-line perpendicular or substantially perpendicular to each other, including but not limited to, volatile memories such as Static Random Access Memory (SRAM), Dynamic RAM (DRAM), non-volatile memory such as NAND Flash (including three-dimensional NAND Flash), NOR Flash, Phase-change RAM (PRAM), Ferroelectric RAM (FeRAM), Correlated electron RAM (CeRAM), Magnetic RAM (MRAM), Resistive RAM (RRAM), XPoint memory and the like.

Abstract: A method is disclosed for designing a test vehicle utilizing a layout of a real integrated circuit (IC) product. The method comprises: importing an original full-chip layout of the real IC product; partitioning the original full-chip layout into probe groups, each probe group comprising probe pads, and, a plurality of IC devices within an area of interest (AOI) having original routing interconnect for those IC devices; selecting a set of IC devices within the AOI; and, for the selected set of IC devices, using pattern extraction to remove the original routing interconnect, and create customized interconnect layers (CIL) to reconfigure connection between the individual IC devices. Incorporating the selected set of IC devices with the CIL into the original full-chip layout creates a modified full-chip layout such that a wafer fabricated using the modified full-chip layout comprises a real product with a built-in test vehicle.
