Slit coater having pre-applying unit and coating method using the same

摘要

A slit coater having a pre-applying unit and a coating method using the same that minimizes the amount of washing solution used and improves the washing effectiveness of a roller by separating the coating solution attached to a pre-applying roller from the washing solution using a coating solution separating apparatus. The slit coater includes: a table on which an object to be processed is mounted; a slit nozzle applying coating solution onto a surface of the object; a pre-applying unit to which the slit nozzle pre-applies the coating solution; and a coating solution separating unit that separates the coating solution spread when the coating solution is pre-applied to the slit nozzle and discharges the separated coating solution.
