Claim 3:
4. A substrate processing apparatus, comprising:
a plurality of first processing units configured to perform a first process on a substrate based on a first parameter;
a plurality of second processing units configured to perform a second process on the substrate based on a second parameter;
a substrate characteristic amount information acquisition part configured to acquire information about characteristics of the substrate subjected to the first process in one of the plurality of first processing units and then subjected to the second process in one of the plurality of second processing units; and
a controller configured to control the plurality of first processing units and the plurality of second processing units,
wherein the controller is configured to:
acquire a data set for each of a plurality of substrates subjected to the first process in the one of the plurality of first processing units and then subjected to the second process in the one of the plurality of second processing units from the substrate characteristic amount information acquisition part, the data set including information specifying the first processing unit in which the first process has been performed, information specifying the second processing unit in which the second process has been performed, and information about a substrate characteristic amount relating to the characteristics of the substrate;
calculate information including an expected value of the substrate characteristic amount, a unit deviation of the first processing unit with respect to the expected value of the substrate characteristic amount, and a unit deviation of the second processing unit 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
correct the first parameter in the first processing unit or the second parameter in the second processing unit based on the calculated information,
wherein the unit deviation of the first processing unit 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 processing unit, and
wherein the unit deviation of the second processing unit 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 processing unit.
