Benefits
Better semiconductor yield analytics with YieldWatchDog
Fewer tools, faster answers, better yield. Investigate low-yield lots in one place, catch excursions earlier and make quality decisions based on complete data.
Benefits
Everything in one place
YieldWatchDog brings wafer sort, final test, parametric (E-test/PCM), inline, defect and equipment data together and correlates them in one platform, including defect and inspection data from any vendor’s equipment. This allows engineers to move from “something changed” to “this tool, this recipe, this time window” without cross-referencing separate systems.
Benefits
Find problems earlier
YieldWatchDog automatically monitors drifting parameters, spatial patterns on wafers and recurring issues across lots. When it detects a problem, it triggers email notifications, reports and tasks — so engineers don’t have to find it manually.
Benefits
Find root causes faster
Trace materials by lot, wafer and die along the supply chain, correlate defects with yield, tool and process data, and find the tools that contribute to yield loss: engineering time goes into diagnosis, not into data assembly.
A real, quantified result
Catch what single-parameter monitoring misses
Together with a manufacturing company, we analyzed a tool failure. The tool had roughly 32 monitored parameters, including pressure and flow. Both pressure and flow stayed within their individual control limits the entire time, even when the problem began. On this tool, however, pressure and flow should move together. When we plotted one against the other, one data point clearly fell outside the expected correlation. DR YIELD’s multivariate monitoring combines the parameters into a single T² value for each data point, and that value crossed its control limit exactly when the tool’s valve started leaking.
With YieldWatchDog multivariate monitoring in place, the manufacturer would have detected the leaking valve two weeks before its actual failure.
FAQ
Frequently asked questions
What should I do if our current yield software is too slow, obsolete or unable to scale with our business growth?
Many of our customers came to us after working with another platform. You can start with a low-cost trial installation using your own data before you decide anything: our experts write the loaders and parsers for your data during the trial, provide training and answer questions, so you see your own lots, wafers and tools in YieldWatchDog. The software is built to process huge amounts of data quickly and has been in use for many years in some of the largest front-end and back-end semiconductor fabs; the Ultimate edition adds massively parallel data import and multiple servers. Licensing is time-based — monthly, quarterly or yearly — with no large upfront investment. YieldWatchDog is vendor-independent — it works from whatever equipment and process data your fab already produces — and you reach the people who build and support the software directly, not a ticket queue.
How does YieldWatchDog handle massive amounts of data?
YieldWatchDog is implemented on a reliable, modern platform that’s capable of processing huge amounts of data quickly and efficiently. The software has been used for many years in some of the largest front end and back end semiconductor fabs and offers a proven solution for handling massive amounts of semiconductor manufacturing and test data.
What automated reporting does YieldWatchDog offer?
Our reporting features create customized reports automatically, according to your specific needs. YieldWatchDog creates them as HTML or PDF documents for engineers, management or your customers.
How does YieldWatchDog support traceability?
With the Material Tracing Module, YieldWatchDog provides full lot-, wafer- or device-level traceability throughout your entire supply chain. Its genealogy tool traces material movements along the entire manufacturing process.
How can YieldWatchDog help me to ramp-up new products?
DR YIELD has supported several product and even factory ramp-ups. Fast access to fully integrated data has been a critical success factor for these ramp-ups.
