Challenge

Testing of semiconductor chips is an expensive and time-consuming operation. Each chip must go through several rounds of complex test suites comprising of thousands of tests. Significant efficiencies can be gained if one can differentiate between good and anomalous chips earlier in the testing cycle

Approach

The team analyzed a dataset comprising of almost a million chips and over thirteen-thousand independent tests. They built several independent ML models, each designed to differentiate between anomalous vs. normal test patterns. These models were then combined to select chips that could be excluded from further testing.
