) Abstract: The study was aimed at the inline detection of the invisible defects lead to end-of-the-line (EOL) data retention soft bin failure
The voltage contrast (VC) inspection was adopted to detect the leakage defects during the technology development of 40nm node wafers
The VC inspection found PMOS leakage by the improper implantation (IMP) of N+ source/drain (NP S/D), which would cause EOL yield loss by data retention soft bin failure
This is a process integration problem which involves the overlay performance of NP S/D photo, the critical dimension (CD) of the photo resist (PR) and the shrinkage of the PR by IMP process
The PMOS leakage was fixed by a series of process improvement actions including the optimization of the optical proximity correct (OPC) for the NP photo mask, to re-target the CD
Instead of EOL CP test, the actions all can be inline verified by the VC inspection with large time advantage
