Patent ID: 7918182

Claim:
A developing apparatus comprising: a substrate holding unit configured to hold a substrate in a substantially horizontal attitude; a developer supply nozzle configured to deliver a developing solution to the substrate, the developer supply nozzle having therein an ejection port that has a length substantially equal to or larger than a width of an effective area of the substrate; a diluent supply nozzle configured to deliver a diluent to the substrate, the diluent supply nozzle having therein an ejection port that has a length substantially equal to or larger than the width of the effective area of the substrate; a temperature regulating unit configured to control temperature of the developing solution to be supplied from the developer supply nozzle, the temperature regulating unit including a first temperature regulating device and a second temperature regulating device; a drive mechanism configured to move the developer supply nozzle and the diluent supply nozzle from one end of the substrate to the opposite end of the substrate; and a control unit configured to control operation of the developer supply nozzle, the diluent supply nozzle, the temperature regulating unit and the drive mechanism, wherein the developer supply nozzle includes: a developer buffer portion having a developer buffer chamber provided in the developer supply nozzle to temporarily store the developing solution; said first temperature regulating device provided to regulate temperature of the developer in the developer buffer chamber; the ejection port of the developer supply nozzle provided below the developer buffer chamber; a communication passage allowing the developer stored in the developer buffer chamber to be fed into the ejection port; a damper rod provided within the ejection port at a location such that the developer fed into the ejection port via the communication passage collides with the damper rod; and said second temperature regulating device is disposed in the damper rod.
