Abstract:
A method for manufacturing a scale in the nanometer range for technical devices which are used for high-resolution or ultrahigh-resolution imaging of structures, the method comprising the steps of:selecting at least two different crystalline or amorphous materials, which are distinguishable from one another when they are imaged using high-resolution or ultrahigh-resolution imaging methods;depositing the at least two different crystalline or amorphous materials one after another in alternating sequence onto a substrate material to form a heterolayer sequence, until a layered stack is obtained;analyzing experimentally the heterolayer sequence using an applied analysis method that is sensitive to layer thicknesses of the heterolayer sequence, the applied analysis method being independent of the high-resolution or ultrahigh-resolution imaging methods used in the technical devices for which the scale is manufactured;evaluating and recording data obtained from the applied analysis method, the data enabling determination of a distance between equivalent hetero-interfaces; andafter the depositing step and before the evaluating and recording data step, exposing the heterolayer sequence by splitting open the heterolayer sequence.
