Abstract

PURPOSE:To suppress the fluctuation of the composition of resist or developer remaining in the flow passage of a nozzle by a method wherein a first supply part having a check valve and a second supply part which supplies cleaning agent and N2 for cleaning out the resist or developer remaining in the tip part of the nozzle after the check valve and for drying are provided. CONSTITUTION:When discharge of resist is discontinued, pressure application to the resist in a resist supply part 2 is discontinued. Then a cover 4 is pressed against a check valve 3 by a force of a spring 5 to cut off the resist from the open air. As the resist remaining in a discharge part 7 is dried and solidified by the contact with the open air, cleaning agent is supplied to a cleaning agent/ N2 supply part 8 and pressurized to clean out the remaining resist. The cleaning agent pushes a cover 10 and fills the discharge part 7 and is discharged with the remaining resist. After that, the supply of the cleaning agent is switched to the supply of N2 by a solenoid valve 21 to supply N2 until the cleaning agent is dried. With this constitution, the aging fluctuation of the component of the resist or developer remaining in the tip part of a nozzle can be suppressed.

Next, as can be seen from the explanations above 0 that explain the action and effect, when the resist is discharged, when the resist in the resist supply section 2 is pressurized, the resist pushes the lid 4 and fills the discharge section 7, and the tip of the nozzle released to the outside. When discharging the resist is to be stopped, the pressurization of the resist by the resist supply unit 2 is stopped. Then, the lid 4 is pressed against the check valve 3 by the force of the spring 5, and the resist is isolated from the outside air. The resist remaining in the discharge section 7 dries and solidifies when exposed to the outside air, so in order to wash it away, pressure is applied while supplying the cleaning liquid to the Nz supply section 8 . The cleaning liquid presses the lid 10 to fill the discharge section 7 and is discharged to the outside together with the resist remaining there. After that, the cleaning liquid is supplied by the electromagnetic pulp 21.
Switch to the supply of NO, and flow NO until the cleaning solution dries.
When the Nt supply is stopped, the lid 10 is pressed against the check valve 9 by the spring 11.

In this embodiment, when the resist is not applied to the wafer, the check valve 3 and the lid 4 shut off the resist from the outside air, and the resist remaining in the discharge section 7 is supplied from the supply section 2. Since the cleaning solution is rinsed away using electromagnetic pulp and the cleaning solution supply is switched to N8 supply to dry the cleaning solution, the nozzle tip may become clogged with resist whose composition changes and solidifies due to contact with outside air. is not deposited on the wafer,
Further, since a resist having a constant composition is always coated with a uniform thickness on the wafer, the dimensional controllability of the resist pattern is improved. Furthermore, this device is constructed with a simple mechanism and is therefore inexpensive.
