Abstract:
1. A liquid processing apparatus comprising: a substrate holding unit configured to hold a substrate horizontally; a solvent nozzle configured to perform a liquid processing with respect to the substrate horizontally held by the substrate holding unit by supplying a solvent from a solvent supply source; an evaporating unit configured to evaporate the solvent supplied from the solvent supply source to obtain vapor of the solvent and transfer the vapor of the solvent to a next stage using a carrier gas supplied from a carrier gas supply source; a cooling unit configured to cool and liquefy the vapor of the solvent transferred from the evaporating unit to the cooling unit by the carrier gas; a storage tank configured to store the solvent obtained by the cooling of the cooling unit; a liquid sending mechanism configured to send the solvent within the storage tank to the solvent nozzle; and a controller programmed to supply the solvent to the substrate through the solvent nozzle prior to supplying a resist liquid to the substrate, wherein the evaporating unit and the cooling unit are connected with a recovery pipe that extends vertically upright, and the top end thereof is bent with an acute angle to extend downward obliquely in a spirally shaped state.
