Calibration gratings – TGXYZ series

Calibration gratings from the TGXYZ series are arrays of different structures comprising rectangular silicon dioxide steps on a silicon wafer. The small square in the center with dimensions 500μm by 500μm includes circular pillars and holes, as well as lines in the X- and Y- direction with a pitch of 5μm. The large square with dimensions 1mm by 1mm contains square pillars and holes with a pitch of 10μm.
The TGXYZ calibration gratings are intended for vertical and lateral calibration of SPM scanners. The vertical non-linearity can be compensated for by using several calibration gratings with different nominal step heights.
The TGXYZ series of Calibration Gratings are supplied mounted on a round 12mm dia metal plate. They are also available unmounted if required.
