Abstract
Systems and methods are provided for designing semiconductor device layouts. For example, an initial layout including multiple target features associated with semiconductor devices is received. One or more dummy features are determined to be inserted into the initial layout. The target features and the dummy features are assigned to multiple masks based at least in part on one or more mask-assignment rules. A final layout is generated for fabricating the semiconductor devices.
