SOLUTION: With respect to a pattern (1) or a pattern (2) generated when the variation of the blooming of an optical system is ±10 nm, the relation between the exposure threshold and the line-width variation of each pattern is represented by such lines (1) or lines (2) as shown in the figure. It is understood from an intersection A of both the corresponding lines (1), (2) that the allowable exposure threshold for making small the line-width variations of both the patterns (1), (2) is set to 0.423. The line-width variation corresponding to the intersection A is 2.1 nm. Since the blooming variation is ±10 nm, the ratio of this line-width variation to the blooming variation is about 1/5.  When an allowable value of the line-width variation corresponding to the blooming variation of 10 nm is set to 1/3, there is brought a scope θ of the exposure threshold into 0.381<=θ<=0.464, by taking the maximum and minimum among the points whereat four auxiliary lines intersect the line of a line-width variation equal to 10/3 nm=3.33 nm.
