SiC-STEP Calibration Samples
6H-SiC (0001) based calibration sample which is designed to perform easy calibrations of an AFM scanner’s vertical movements in several nanometers interval.
The simplicity of calibration of the calibration process is provided by the nearly uniform distribution of half-monolayer high steps (either 0.75 or 1.5nm) on the sample surface demonstrating both chemical and mechanical stability.
The step height corresponds to the half of the lattice constant of the 6H-SiC crystal in the (0001) direction.

Grating type TGX
The silicon calibration grating from the TGX series is an array of square holes with sharp undercut edges formed by the (110) crystallographic planes of silicon.
The typical radius of the edges is less than 5 nm.
Application
The TGX calibration gratings are intended for lateral calibration of SPM scanners. They can also be used for:
- detection of lateral non-linearity, hysteresis, creep, and cross-coupling effects
- determination of the tip aspect ratio
For accurate quantification of images of calibration gratings from the TGX series, we recommend using the Scanning Probe Image Processor (SPIP) designed by Image Metrology.

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.
