Description
第1ノズルから勢いよく液体を供給することで、洗浄に用いられた液体を効率よく基板から排出でき、洗浄力が向上する。
このように第1領域および第2領域を設定することで、洗浄に用いられた液体を効率よく基板から排出できる。
これにより、液膜が保護されるとともに、第2ノズルから供給される液体が基板Wの外に向かって流れるのが妨げられない。
前記第2ノズルからの液体供給方向は、前記基板の回転方向と逆行しないのが望ましい。
前記第2ノズルからの液体供給方向と、前記洗浄部材と前記基板とが接触する位置における前記洗浄部材の回転方向と、が一致するのが望ましい。
これにより、第1ノズルから供給される液体の勢いを増すことができる。
