VISION 200/300-M

DipView

Vision solutions are intended to provide wafer manufacturers with advanced solutions to measure SEMI-compliant geometry parameters and critical surface Nano-topography with non-contact technology. The equipment is designed for manual loading metrology and inspection. It measures bow, warp, TTV, LTV, and qualifies surface roughness, nano-topography down to nm level in one single shot measurement. Its full field of view, leading edge throughput and small footprint bring the best TCO adapted to volume wafer fabs.

Advanced Features

•    High measurement speed < 10sec

•    Best lateral resolution : <60mm on 300mm

•    Full field of view for 200mm or 300mm

•    Dual side measurement / No stitching

•    Manual wafer loading on tray

•    Software: Easy-to-use software interface
