Corrective Action Status(if required) : CA pending CA determinedProcess Root Cause Corrective Action: Set up finger miss-center measurement for FSMC 80mil chip size, when production produced 80mil chip size, operator needs to measure finger miss-center dimension as below definition. --2019.11.24Process engineer calculated dimension value according to chip size, bottom pad length, and combined chip position tolerance, calculated out the permissible space to top finger—13.3mil.We issued EES to implement this specification in line, implement it and collect the data.
