It is well known that orbit width of Sinkansen is managed strictly for safety transportation. This MICRO-RAILROAD is made of the laser interference exposure and the anisotropic etching technology using (110) silicon plate, which realizes high precision that has 0.24 ± 0.001 pitch width. It is expected to use as standard of minute metrology indispensable for the field of advanced technology.
