Description
The TGF11 calibration gratings exhibit a one-dimensional arrays of trapezoid steps. These steps are etched into a silicon substrate along the (111) planes in mono-crystalline silicon. The result is a planar structure with smooth sidewalls on the trapezoid at an angle of 54.74°. The TGF11 grating is useful for assessment of scanner non-linearity in the vertical direction. Calibration of the lateral force can be obtained by analyzing the contact response on the flat and sloped planes. Calibrated pitch is 10um with a non-calibrated step height of 1.75um. Chip size is 5x5x0.3mm with an active area of 3x3mm. Supplied either unmounted or mounted on a 12mm AFM disc.
