| description | A global dynamic detection method for a pellicle membrane (122) of a photomask includes: causing the pellicle membrane (122) to undergo broadband oscillation; applying a broadband signal to the pellicle membrane (122) undergoing multi-frequency oscillation; transforming an optical time-domain signal reflecting off the pellicle membrane (122) to obtain a frequency spectrum with multiple resonance frequencies; and detecting the pellicle membrane (122) with the frequency spectrum comprehensively to ensure the quality of the pellicle membrane. A global dynamic detection system for use with the global dynamic detection method is further provided. |
