PV-1000 Wafer Metrology Systems The PV-1000 solar wafer measurement series are ideal for both process development and production environments. Using MTII’s exclusive Push/PullTM capacitance probe technology, each PV-1000 module provides up to three pairs of probes for measurement of maximum, minimum and average thickness, as well as total thickness variation (TTV) and wafer bow. For applications requiring additional thickness channels, multiple PV-1000 modules can be chained together for unlimited line scans on the wafer. Integrated data acquisition and control electronics analyze and...
