Stress Mapping System
128 Series - Frontier Semiconductor, Inc, (FSM)
The FSM 128 Series systems are room temperature, full-wafer 2D/3D stress mapping systems. 128 systems use FSM's patented non-contact Opti-Lever dual-laser auto-switching technology featuring a micropositioning detector to measure the laser beam deflection with high precision over a large dynamic range of small to large bow or stress. FSM's stress gauges have the ability to scan 1000 points per inch in seconds for high resolution, high precision stress mapping on blanked and patterned wafers.
