Described herein are methods and systems for efficiently preparing a wafer layout for processing into a photomask. Portions of layouts containing semiconductor features and designs that are frequently used can be stored in a database. These portions can be post-decomposition, with all treatment and error checking already performed upon them. When a wafer layout is received for processing into a photomask, the processing and decomposition time can be reduced by analyzing the layout, and replacing sections of the layout with the portions from the database that have already been decomposed and processed. As these sections no longer need to be decomposed, error checked, and treated, the processing time is greatly reduced, and photomasks can be made quicker and more efficiently.
