## Wire brief

According to public reporting via Semiconductor Engineering, manufacturers are using test data and predictive models to identify marginal chips and determine when additional screening is justified.

In related context, test, Measurement & Analytics ? ps and determine when additional screening is justified. November 10th, 2026 - By: Gregory Haley Key Takeaways: Chips that pass identical tests can carry very different reliability risks, because marginal behavior often hides inside specification limits. Device-level models, cross-insertion data, and physical inspection can flag suspicious passing parts, but an anomaly isn’t proof of a defect.

Reporting also notes that extra screening pays off only when the added test can expose the suspected weakness at a lower cost than the failures it may prevent. A chip passes wafer sort, moves through assembly, and passes final test. Nothing in its results gives anyone a reason to hold it. Yet another chip with nearly identical results could fail in the field because of a weakness neither test exposed, whether that’s a thin timing margin, a slight resistance shift, or a combination of measurements that looks harmless when each is viewed alone.

Points still worth watching: The challenge for manufacturers is figuring out which of those passing chips deserve another look without retesting everything. This Silicon News Wire item is a paraphrased brief; full wording remains on the origin page.
