We present a necessary condition for an arbitrary 2-dimensional pattern to be printable by optical projection lithography. We call a pattern printable if it satisfies a given set of edge-placement tolerances for a given lithography model and process-window. The test can be made specific to a lithography model, or it can be made generic for a wavelength and numerical aperture. In the generic form, if a pattern is found to be not printable, the conclusion is valid for all RET technologies except for non-linear techniques such as litho-etch-litho-etch double-patterning and multi-photon lithography. The test determines printability of a target layout without applying RET/OPC.
