Patent ID: 7008124

Claim:
A substrate processing device comprising: a cassette section from and into which a cassette housing a plurality of substrates constituting lots is taken and put; a processing section to execute a plurality of processes for the substrates in sequence; a plurality of solution processing units disposed in the processing section to process the substrates by using a predetermined processing solution; a transfer mechanism to take out the substrates from the cassette of the cassette section and to transfer the substrates to the processing section; substrate carrying mechanisms to receive the substrates from the transfer mechanism, to carry the substrates in sequence in the processing section, and to carry the substrates out to the cassette section; a cyclic route disposed in the processing section, along which the substrate carrying mechanisms make cycle movements; and a control section to make recipes which define operations of the transfer mechanism, the substrate carrying mechanisms and the solution processing units, to obtain a cycle time and a dummy dispense time based on the recipes, to obtain a substrate transfer stop period based on the recipes, the cycle time and the dummy dispense time, to stop transfer of a substrate of a succeeding lot from the cassette section to the processing section during the substrate transfer stop period, to cause the solution processing unit to execute dummy dispense during the substrate transfer stop period, and then to transfer the substrate of the succeeding lot to the processing section by the transfer mechanism.
