Title:
COATING APPARATUS AND COATING METHOD
Document Type and Number:
WIPO Patent Application WO/2018/037670
Kind Code:
A1
Abstract:
The present coating apparatus is provided with: a back-up roller (10) for holding a substrate; a driving unit for rotating the back-up roller (10); a nozzle (41) for discharging a coating liquid toward the surface of the substrate that is held on the back-up roller (10); and a heating part for heating the coating liquid applied on the surface of the substrate. Said coating apparatus is also provided with a gas-blowing unit (42) for blowing a gas near the discharge port (411) of the nozzle (41). As a result, even if the solvent from the coating liquid is vaporized near the discharge port (411), the gas containing the vapor of said solvent is replaced with gas discharged from the gas-blowing unit (42). Accordingly, it is possible to limit the condensation of the solvent vaporized from the coating liquid in the vicinity of the discharge port (411) of the nozzle (41), thereby making it possible to limit defective discharge of the coating liquid due to condensation of the solvent.
