    摘要: A die seal of a semiconductor device may be provided with a varying pattern density such that a gradient between the die region and the die seal may be reduced. Consequently, for a given width of the die seal, a required mechanical stability may be achieved, while at the same time differences in topography between the die region and the die seal may be reduced, thereby contributing to superior process conditions for sophisticated lithography processes.
