Patent ID: 7094440

Claim:
A substrate treatment method in which a treatment by supplying a treatment solution to a substrate is successively performed for a plurality of substrates, comprising the step of: during the performance of the successive treatments, performing between the treatments a plurality of pre-dispenses for different purposes of the treatment solution, wherein at least a recipe of the treatment solution to be pre-dispensed or a start condition of the pre-dispense is determined for each of the pre-dispenses and wherein the substrate treatment method is performed by a treatment apparatus by supplying the treatment solution to the substrate, the treatment apparatus including: a treatment solution supply mechanism for supplying the treatment solution and performing a pre-dispense of the treatment solution; and a main controller for controlling the pre-dispense, wherein the main controller controls discharge amounts an start conditions of a plurality of pre-dispenses, wherein the main controller has a measuring unit, wherein the measuring unit measures an integrated time from the time of a preceding pre-dispense or the time of a preceding reset, for each of the pre-dispenses, and wherein the main controller conducts a control such that each of the pre-dispenses is performed when the integrated time reaches a predetermined set time, the plurality of pre-dispenses are given priority levels, when the pre-dispense at a high priority level is performed, the integrated time of the pre-dispense at a priority level lower than that is reset, and when the pre-dispense at a low priority level is performed, the integrated time of the pre-dispense at a priority level higher than that is not reset.
