Claim:
1. A CAD-based method for designing a lithographic mask for nanowire-based devices, the method comprising the steps of: (a) creating a design for the lithographic mask from existing design data, wherein the design for the lithographic mask includes continuous active area shapes for each of the nanowire-based devices; (b) expanding the continuous active area shapes to join all of the continuous active area shapes in the design for the lithographic mask together to form a single polygon shape; (c) removing each of the continuous active area shapes from step (a) from the single polygon shape resulting in one or more landing pad shapes; (d) dividing the continuous active shapes from step (a) into one or more nanowire mask shapes; and (e) merging the landing pad shapes with the nanowire mask shapes to form the lithographic mask which now includes the nanowire mask shapes and the landing pad shapes for anchoring the nanowire mask shapes.
