ABSTRACT:
A mask of the present invention has a circuit pattern to be transferred to a substrate via an optical system, and an inspection pattern to be used for a measurement of a line width of the pattern transferred to the substrate. By using such a mask, the time for proceeding from inspection to actual device exposure can be shortened.
