Method for patterning a radiation beam, patterning device for patterning a radiation beam
A multiple-die mask pattern is arranged with dies having the same pattern in mutually opposite orientations. The method for arranging the dies includes analyzing the pattern of a single die to identify a pattern characteristic property which is non uniformly distributed over the area of the die. If...

| description | A multiple-die mask pattern is arranged with dies having the same pattern in mutually opposite orientations. The method for arranging the dies includes analyzing the pattern of a single die to identify a pattern characteristic property which is non uniformly distributed over the area of the die. If the distribution is found to be asymmetric, a line separating the die area into two half-die areas is defined with respect to which the asymmetry is apparent. Half-die areas of different dies with the same pattern characteristic property are grouped together in the mask pattern. The resulting enhanced symmetry of the distribution of the pattern characteristic property over the mask area increases lithographic processability and thereby improves die yield. |
