Do inspections really help?

Research output: Chapter in Book/Report/Conference proceedingConference contributionpeer-review


"The potentially dire consequences of not detecting an electrical fault early during the process have motivated technology managers in the semiconductor industry to introduce an inspection step after about every ten process steps."[1] Researchers added that "if new inspection operations are added, the delay to get this measurement result is reduced, and the wafer at risk could thus also be reduced."[2] Inspections, however, like processes, are imperfect and prone to errors, which have devastating effects. Despite their significance, these effects are rather unnoticed. It turns out that when processes are in-control and perform reasonably well, the consequent costs of inspections may exceed the saving, as demonstrated in this presentation.
