Abstract:
A management system for a plurality of semiconductor exposure apparatuses, and for controlling each exposure when a semiconductor device is manufactured, said system comprising:first means for managing distortion data of each illumination condition for each of the semiconductor exposure apparatuses; second means for designating a product and a process comprising a reference process; third means for acquiring an illumination condition of the product and process designated by said second means; fourth means for acquiring a process to be searched as a reference process including the process designated by said second means; fifth means for acquiring an illumination condition of the process to be searched acquired by said fourth means; sixth means for acquiring distortion data of an illumination data of the process designated by said second means for each of the semiconductor exposure apparatuses; seventh means for acquiring distortion data of the illumination condition acquired by said fifth means corresponding to the process to be searched acquired by said fifth means for each of the semiconductor exposure apparatuses; eighth means for acquiring a permissible value of an alignment error caused by distortion of the process to be searched acquired by said fourth means; ninth means for comparing the distortion data acquired by said sixth means with the distortion data acquired by said seventh means, and for calculating an alignment error caused by distortion of a combination of the semiconductor exposure apparatuses; tenth means for comparing the alignment error calculated by said ninth means with the permissible value acquired by said eighth means; and eleventh means for displaying an evaluation value of a semiconductor exposure apparatus used for the reference process on the basis of the number of said semiconductor exposure apparatuses whose alignment error is within a predetermined permissible error, which is obtained by a comparison result of said tenth means.
