Prevention of Yield
Excursions

YieldWatchDog enables you to quickly identify
potential threats that may cause yield degradation.
As lots typically move with varying speed through
the semiconductor lines, there are usually early
warning signs for any major yield problem.

If they remain undetected, the subsequent costs can be huge.
YieldWatchDog provides the capability to detect such early warnings with high
sensitivity. Thus, you will be able to react on early warning signs, and not only
after the yield degradation strikes. This time advantage can save millions of
dollars.
Ultimately, many yield problems can be associated to malfunction of a particular
processing tool. YieldWatchDog with the optional Equipment Monitoring
Module or the Spatial Signature Control Module can even warn you of
potential threats arising from specific equipment.
