Substrate processing system, method of confirmation of its state of use, and method of prevention of illicit use

摘要

[PROBLEM] To enable confirmation of whether a substrate processing system is being illicitly used and preventing that use when there is the fact of illicit use. [MEANS FOR SOLUTION] A license file LF is a file encrypting license information L including usage terms of a substrate processing system for a specific user. A match confirmation program P2 confirms the match between the content of the license file LF decrypted by a decryption program P1 and device information DI, network information NI, and current time CT obtained from the substrate processing system to confirm the existence of the fact of illicit use. If there is illicit use, the control program P3 stops operation of the substrate processing system until predetermined action is taken based on the information from the match confirmation program P2.
