Sample for Coordinates Calibration and Method for Fabricating the Same

A sample for coordinates calibration including (1) a substrate having a circular plate-shape, and (2) multiple intentional defects that form a grid pattern with squares as unit grids on a surface of the substrate, the intentional defect providing a center point of the grid pattern coinciding with a...

Beschreibung
Zusammenfassung:	A sample for coordinates calibration including (1) a substrate having a circular plate-shape, and (2) multiple intentional defects that form a grid pattern with squares as unit grids on a surface of the substrate, the intentional defect providing a center point of the grid pattern coinciding with a center point of the substrate and, letting the maximum value of a number of the unit grids arranged from the center point of the substrate in radial directions be N (a natural number equal to or larger than two), a number of the intentional defects formed at equal spaces along one side of the unit grid being N+1 including the two intentional defects providing a vertex of the unit grid is proposed.
