1. A method of enhancing the image resolution in a lithographic system, comprising: decomposing a reticle pattern into at least two constituent sub-patterns; coating a substrate with a pre-specified photoresist layer, said pre-specified photoresist layer having reduced memory reaction characteristics; exposing a first of said at least two constituent sub-patterns by directing a projection beam through said first sub-pattern such that said lithographic system produces a first sub-pattern image onto said pre-specified photoresist layer of said substrate; processing said exposed substrate; exposing a second of said at least two constituent sub-patterns by directing said projection beam through said second sub-pattern such that said lithographic system produces a second sub-pattern image onto said pre-specified photoresist layer of said substrate, wherein said exposing combines said first and second sub-pattern images to produce a desired pattern on said substrate.
