Abstract
A method including the operations of receiving a preliminary device layout including a plurality of active areas, analyzing the preliminary device layout to identify empty areas between the plurality of active areas, determining the configurations of the active areas bordering the empty areas, selecting a transition cell from a transition cell library in which the transition cell has a transitional configuration for reducing density gradient effects in the active areas adjacent the transition cell, and inserting the transition cells into the empty areas to define a modified device layout.
