1.Film Stress and Wafer Bow Measurement Systems. ( Room Temperature and High Temperatures – for Si or GaAs applications)
We pioneered the optical lever (optilever)™ laser scanning technique for measuring film stress and wafer bow. Over 400 systems are installed worldwide. Our system is used routinely by fabs to monitor the film deposition process, which if not controlled, could lead to delamination, cracking and void formation in the wafer.
