NvisANA

NvA-MW300 is a world first in-line wafer metallic non-visual defect detection system to prevent yield drop or wafer scraps by metal contamination in the semiconductor manufacturing Fabs.

It is a standalone and fully automated system with a built-in VPD and an integrated ICP-MS. And it supports FA and Host communication and it has its own auto calibration function and safety features for the in-line use not only Q-Labs application.
