Fabless yield management software
Test data from every foundry and OSAT in one format you control — loaded automatically and monitored as it arrives.
What matters
Your data comes from many partners
One format for every partner
Foundries deliver PCM/WAT data, OSATs and test houses deliver wafer sort and final test data — each in its own format. YieldWatchDog loads STDF, ATDF, CSV, Excel and other formats into one data model, and our experts write the loaders for your partners’ formats.
Every partner lot checked on arrival
Each imported lot is checked automatically: SPC rules run on your parameters, Spatial Signature Control looks for known patterns on the wafer maps, and the responsible engineers are notified when something changes.
Quality and traceability in the supply chain
Part Average Testing screens parts that pass the test limits but behave suspiciously — built for automotive and other zero-defect industries. Material Tracing follows lots, wafers and dies along the supply chain, through final test.
Why YieldWatchDog
Yield control without a fab
As a fabless company, you depend on the data your partners deliver. YieldWatchDog brings foundry and test data from every partner into one consistent data model, so your engineers compare partners, products and lots in one place, with no manual conversion.
"With the YieldWatchDog software, Inova now has a tool that is capable of parallel production data processing, enabling the rapid load and analysis of large amounts of information. This ensures a continuous delivery of products with the highest quality."
Typical edition
The edition that usually fits
YieldWatchDog Professional
Professional is the typical edition for fabless companies: 4 CPU cores, 4 concurrent clients (upgrades to 8, 12 or 16 possible) and 60 annual support hours. A large fabless company may need a higher edition because of its number of users.
Editions are sized by scale, not by company type. We’ll help you choose.
