Zusammenfassung: | PURPOSE: A critical dimension correction mask is provided to fabricate a critical dimension mask with a prominent critical dimension by forming the second and the third transmission areas smaller or larger than the first transmission area. CONSTITUTION: The first transmission area(41) is formed by a multitude of transmission areas formed on a quartz substrate according sizes or types. The second transmission area is reduced repeatedly as much as -2 greed sizing(51) and -1 greed sizing(52) of the first transmission area(41). The third transmission area is increased repeatedly as much as +1 greed sizing(53) and +2 greed sizing of the first transmission area(41). The first transmission area(41), the second transmission area, the third transmission area, and a fine transmission area(42) are formed on a chrome layer(31). The fine transmission area(42) is formed by performed a mask writing process when a pattern generation work is performed. |
