Abstract:
A method of determining set temperature trajectories for a heat treatment system that continuously conducts a first heat treatment process and a second heat treatment process to an object to be processed, said method comprising the steps of:conducting the first heat treatment process to a first test object to be processed, by using a temporary first set temperature trajectory; measuring a result of the first heat treatment process conducted to the first test object to be processed; determining a first set temperature trajectory for the first heat treatment process by correcting the temporary first set temperature trajectory on the basis of the measured result of the first heat treatment process; conducting the second heat treatment process to a second test object to be processed to which the first heat treatment process has been conducted by using the determined first set temperature trajectory, by using a temporary second set temperature trajectory; measuring a result of the first heat treatment process and the second heat treatment process conducted to the second test object to be processed; and determining a second set temperature trajectory for the second heat treatment process by correcting the temporary second set temperature trajectory on the basis of the measured result of the first heat treatment process and the second heat treatment process.
