Inventor: OHTAGURO HIROKI
IPC: H01L21/02
Filed: 2018-10-11
Abstract: In a nozzle receiving part, when a solvent is sucked into a tip part of a nozzle to form a liquid layer of the solvent, the liquid of the solvent supplied to the nozzle receiving part can be saved. A nozzle waiting device allows the nozzle to stand by in the nozzle receiving part, supplies the solvent from a solvent discharge port at a first flow rate, forms a liquid film to close a discharge port of the nozzle, and then supplies the solvent at a second flow rate smaller than the first flow rate. The second flow rate is a flow rate at which the discharge port of the nozzle can be kept closed by the solvent. The liquid film formed on the discharge port of the nozzle comes into contact with the solvent, thereby the solvent is sucked into the tip part of the nozzle by the surface tension, and the liquid layer of the solvent is formed. Therefore, it is not necessary to form a liquid reservoir part for the solvent in the nozzle receiving part. Moreover, since the supply flow rate is reduced from the first flow rate to the second flow rate while the solvent is supplied from the solvent discharge port, the liquid of the solvent can be saved.
