Chuck flatness
WebNew sensor design insensitive to wafer/chuck flatness. Rapidity of even full wafer mapping measurements ensures an impressive throughput and the ability to monitor and control the epitaxial process Improved new software has multiple benefits, such as: highly configurable, multitasking, real-time data monitoring, simplified recipe generation ... WebON/OFF switching doesn't influence plate flatness. The fine-pitched magnetic poles make it ideally suitable for small and thin workpieces. Brazing treatment protects the top plate from coolant corrosion. Strong holding power, residual magnetism reduced. Specially designed for high precision operation.
