A case of multiple failures at the end of line (EOL) electrical test (E-test) was encountered in wafer fabrication. In this paper, we will present a significant study of multiple E-test failure case, using CAMECA IMS Wf instrument. The results show that the failure is relate to the quality of incoming starting materials.
