Scan testing has been the foundation of digital-device production test for many years. Several innovations have been developed to keep up with the growth in pattern-set sizes brought about by large ...

The old adage “time is money” is highly applicable to the production testing of semiconductor devices. Every second that a wafer or chip is under test means that the next part cannot yet be tested.

Download this article in PDF format. Finding the right balance among test cost, test quality, and data collection for running diagnosis requires consideration of several competing factors. Luckily ...

Design for testability (DFT) works to make a circuit more testable to ensure that it was manufactured correctly. Alfred Crouch explains the purpose of DFT in his book, Design-For-Test for Digital ICs ...
