ABOUT THE DATA
• Data consists of die level test information for 1 wafer
• 12,000+ dies with 100+ tests done for each of the die
• Network was built using all the test columns
• Test Result column with pass/fail flag used as metadata
GOAL OF THE ANALYSIS
• Identify different subgroups of dies based on similar test
information
• Find tests that uniquely identify failed die subgroups

• Pinpoint wafer anomalies that result in scrap and lost revenue
• Previously required at least two days of analysis to identify even the

CHALLENGE
most systemic anomalies
SOLUTION
• Accelerated the analysis of wafer data and yield rates to identify
and resolve issues
• Identified additional systemic anomalies previously dismissed as
“random”
• Estimated to save hundred million dollars in the first year from a
reduction in scrap by reducing yield loss by 10%
