An alignment mark includes a first mark usable for global alignment measurement
in the direction of a scribe line, and a second mark usable for pre-alignment measurement
in a direction perpendicular to the direction of the scribe line. The first mark
is formed by arranging a plurality of strip-shaped X measurement marks whose longitudinal
direction is perpendicular to the direction of the scribe line. In the second mark,
the strip-shaped second measurement marks are arranged at the two ends of the first
mark such that the longitudinal direction of the second measurement mark is perpendicular
to that of the first measurement mark. The alignment mark can be shared by global
alignment and pre-alignment, and applied to a narrow scribe line.
