Calibration gratings
The calibration gratings feature one-dimensional arrays of trapezoidal steps etched into a silicon substrate.
The calibration gratings feature one-dimensional arrays of trapezoidal steps etched into a silicon substrate.
The calibration gratings feature one-dimensional arrays of trapezoidal steps etched into a silicon substrate. The sidewalls of the structures are very smooth and planar surfaces with well-defined orientation formed by the (111) crystallographic planes in monocrystalline silicon. The sidewalls and the horizontal top surfaces form an angle of 54°74’.
