    Abstract: The present invention includes a packaged coated workpiece. The packaged coated workpiece has: (1) a workpiece coated with a resist film sensitive to optical radiation, particulates or chemical contaminants; (2) an inner barrier sealed to enclose the coated workpiece and optionally a first getter agent, to produce a sealed first enclosure; and (3) an outer barrier sealed to enclose the sealed first enclosure and optionally a second getter agent, provided that the packaged coated workpiece has at least one getter agent, to produce a packaged coated workpiece suitable for storage for a period of at least one week without substantial loss of sensitivity, resolution or performance. The present invention also includes a process for preparing a packaged coated workpiece and a method of increasing the storage time of a coated workpiece to at least one week without substantial loss of sensitivity, resolution or performance.
