A Calibration Wafer Standard is a NIST traceable, PSL wafer standard with Size Certificate included, deposited with monodisperse polystyrene latex beads and narrow size peak between 50nm and 10 microns to calibrate the size response curves of Tencor Surfscan 6220 and 6440, KLA-Tencor Surfscan SP1, SP2 and SP3 wafer inspection systems. A Calibration Wafer Standard is deposited as a FULL Deposition with a single particle size across the wafer; or deposited as a SPOT Deposition with 1 or more particle size standard peaks, precisely located around the wafer standard.
