Tessent Diagnosis

Categories: Tessent

Tessent Diagnosis will teach you to capitalize on the methods of defect discovery on failing devices in a production environment. Using the defect reports from YieldAssist you will be able to plan the analysis process in determining the root cause of  failure, reducing time and improving your hit rate. With the correlation between the 'Logical netlist' and the Physical layout you will have a indication of the most likely area where to begin the failure analysis. View course details ↓
