Claim 0:
1. A substrate processing control method in a substrate processing apparatus that includes a first factor including a plurality of first levels for performing a first process on a substrate based on a first parameter, and a second factor including a plurality of second levels for performing a second process on the substrate based on a second parameter, the method comprising:
an acquisition step of acquiring a data set for each of a plurality of substrates subjected to the first process at the first level and then subjected to the second process at the second level, the data set including information specifying the first level at which the first process has been performed, information specifying the second level at which the second process has been performed, and information about a substrate characteristic amount relating to characteristics of the substrate;
a calculation step of calculating information including an expected value of the substrate characteristic amount, a level deviation of the first level with respect to the expected value of the substrate characteristic amount, and a level deviation of the second level with respect to the expected value of the substrate characteristic amount based on the data set corresponding to each of the plurality of substrates; and
a correction step of correcting the first parameter at the first level or the second parameter at the second level based on the information calculated in the calculation step,
wherein the level deviation of the first level corresponds to a deviation from the expected value of the substrate characteristic amount after the first process is performed on the substrate by the first level, and
wherein the level deviation of the second level corresponds to a deviation from the expected value of the substrate characteristic amount of the substrate after the second process is performed on the substrate by the second level.
