Wafer map analysis
Spatial failure patterns traced to the tool
How a run goes
The steps this agent takes, in order, and what each one leaves behind.
Pulls probe maps and lot processing history
Classifies wafer maps by spatial signature such as edge, center, scratch and repeating patterns
Clusters the maps and joins clusters to tool routes
Traces each signature to the tools and chambers the affected lots shared
Drafts the finding with the suspect step ranked first
Produces an evidence pack for the process engineer with the wafers and the suspect step
