ABICS Series E120

As device patterns become finer, the practical application of next-generation EUV lithography is approaching, and the installation of inspection systems capable of quality control for EUV mask blanks is urgently needed.

We have developed the ABICS "E120", an EUV mask blank defect inspection/review system that contributes to defect management and yield improvement of EUV mask blanks.

Since this system employs an inspection/review method using EUV light, it enables selective detection of printable defects and defect analysis using EUV light. These capabilities greatly contribute to defect management and yield improvement of EUV mask blanks.
