Summary: | Method for producing a mask for the extreme ultraviolet wavelength range proceeding from a mask blank (250, 350, 550, 950) having defects (220, 320, 520, 620, 920), wherein the method comprises the following steps: a. classifying the defects (220, 320, 520, 620, 920) into at least a first group and a second group; b. optimizing arrangement of an absorber pattern (170) on the mask blank (250, 350, 550, 950) in order to compensate for a maximum number of the defects of the first group by means of the arranged absorber pattern (170); and c. applying the optimized absorber pattern (170) to the mask blank (250, 350, 550, 950).
种由掩模坯体(250,350,550,950)制造极紫外波长范围的掩模的方法,所述掩模坯体具有缺陷(220,320,520,620,920),其中,所述方法包括下列步骤:a.将所述缺陷(220,320,520,620,920)归类为至少个第组和第二组;b.优化掩模坯体(250,350,550,950)上的吸收体图案(170)的布置,以通过布置的吸收体图案(170)补偿最大数量的第组的缺陷;以及c.将优化的吸收体图案(170)施加到掩模坯体(250,350,550,950)。 |
