A system and method are provided for detecting latent defects in a mask or reticle, which defects may vary as a function of radiation at exposure wavelengths. By way of example, the mask or reticle is inspected, exposed to radiation at a specified wavelength, and then reinspected. A correlation between the inspection results before and after exposure provides an indication of exposure-related defects, which may include defect growth and/or formation of defects caused by the exposure. By way of further illustration, the combination of inspection and exposure of a mask or reticle may be implemented with respect to a pellicized mask or reticle so as to detect additional defects related to use of the pellicle with the mask or reticle.
