Substrate processing apparatus, substrate processing method and storage medium

A substrate processing apparatus, comprising:

• a mounting unit configured to mount thereon substrates to be processed;
• a substrate processing unit including a plurality of processing modules each configured to perform a process on the substrate;
• a substrate transfer device provided between the mounting unit and the processing modules;
• a parameter storage unit configured to store plural sets of transfer parameter in which a set value of an operating speed of the substrate transfer device based on a processing number of substrates in the substrate processing unit corresponds to a processing number of substrates per a unit time in the substrate processing unit;
• a parameter selecting unit configured to compare a processing number of substrates per a unit time in the substrate processing unit, which is determined based on a recipe corresponding to the process performed on the substrate, with the processing numbers of substrates corresponding to the transfer parameters stored in the parameter storage unit, and configured to select, from the parameter storage unit, a transfer parameter corresponding to the minimum processing number of substrates among the processing numbers of substrates corresponding to the transfer parameters each having the processing number of substrates equal to or larger than the processing number of substrates determined based on the recipe;
• and
• a transfer control unit configured to control the substrate transfer device based on a set value of the transfer parameter selected by the parameter selecting unit.
