Abstract:
1. A conditioning method for conditioning interiors of a plurality of process chambers of a substrate processing apparatus in which predetermined processes are performed on a substrate, the process chambers including a first and a second process chamber combined to perform a series of processes for the substrate, the method comprising: performing conditioning of the interior of the first process chamber if a first integrated value set in connection with the process of the substrate reaches a set value N1; setting the second process chamber in a standby state when the conditioning of the first process chamber starts and the series of processes is stopped; determining at least whether or not a second integrated value set in connection with process of the substrate in the second process chamber is equal to or greater than a set value N2; starting count of a third integrated value in the second process chamber if the second integrated value is equal to or greater than the set value N2; and performing a conditioning of the second process chamber if the third integrated value exceeds a set value N3, wherein the second process chamber is set to perform the conditioning, independently of the first process chamber, when the second integrated value reaches a set value N4 which is larger than the set value N1, and the set value N2 is equal to a value obtained by subtracting the set value N1 from the set value N4, wherein the first integrated value becomes zero by the performance of the conditioning of the first process chamber and is calculated from an end of an immediately preceding conditioning of the first process chamber, and the second integrated value becomes zero by the performance of the conditioning of the second process chamber and is calculated from an end of an immediately preceding conditioning of the second process chamber.
