Abstract:
A substrate treatment method according to the present invention is a substrate treatment method of treating at least one substrate in a treatment tank with treatment liquid. The substrate treatment method includes the following processes of: acquiring in advance treatment information of the substrate to be treated in the treatment tank; specifying a predicted concentration change pattern corresponding to the acquired treatment information of the substrate by referencing correspondence information describing a plurality of situations possible for the treatment information and a plurality of concentration change patterns of the treatment liquid prepared in advance to respectively correspond to the plurality of situations of the treatment information; and carrying out concentration control of the treatment liquid based on the predicted concentration change pattern while the substrate is treated in the treatment tank.

Claim (Index 9):
A substrate treatment apparatus comprising:\n a treatment tank that stores treatment liquid and immerses at least one substrate in said stored treatment liquid to carry out substrate treatment of said substrate; a backup tank that is provided separately from said treatment tank, the backup tank replenishing replenishment liquid prepared to a predetermined concentration toward said treatment tank; liquid sending means that sends said replenishment liquid from said backup tank toward said treatment tank; an acquisition part that acquires in advance treatment information about said substrate to be immersed in said treatment tank; a storage part that stores correspondence information describing a plurality of situations possible for said treatment information and describing a plurality of concentration change patterns prepared in advance to respectively correspond to said plurality of situations of said treatment information; a specifying part that specifies a predicted concentration change pattern corresponding to said treatment information of said substrate acquired by said acquisition part by referencing said correspondence information; and control means that executes\n concentration prediction control of predicting a future concentration of said treatment liquid based on said specified predicted concentration change pattern, \n replenishment liquid concentration specifying control of specifying the concentration of replenishment liquid capable of changing said future concentration, \n preparation control of preparing said replenishment liquid in advance in said backup tank before replenishing said replenishment liquid from said backup tank toward said treatment tank, and \n liquid sending control of controlling said liquid sending means so as to send said prepared replenishment liquid from said backup tank toward said treatment tank during said substrate treatment.
