Process for making semiconductor dies, chips, and wafers using in-line measurements obtained from DOEs of NCEM-enabled fill cells

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).

Forecasting wafer defects using frequency domain analysis

Defect information obtained from a test wafer is received. The test wafer was fabricated according to an Integrated Circuit (IC) design layout. A plurality of first regions of interest (ROIs) is received based on the defect information. The first ROIs each correspond to a region of the IC design layout where a wafer defect has occurred. A frequency domain analysis is performed for the first ROIs. A wafer defect probability is forecast for the IC design layout based at least in part on the frequency domain analysis.
