Summary:To provide a substrate processing apparatus capable of suppressing processing fluid supplied to a substrate from being rebounded by a substrate support.SOLUTION: A substrate processing apparatus 100 includes a spin base SB, a plurality of substrate supports MC, a nozzle 19, a lifting part 7 and a chamber 1. The spin base SB has a gas supply port 45. The plurality of substrate supports MC is arranged to the spin base SB, and supports a substrate W by contacting the substrate W. The nozzle 19 supplies first processing fluid FL1 to the substrate W supported by the plurality of substrate supports MC. The gas supply port 45 supplies a first gas GA between a rear surface F2 of the substrate W and the spin base SB to generate a negative pressure so that the spin base SB supports the substrate W while the plurality of substrate supports MC does not support the substrate W. When the substrate W is supported by the spin base SB by the supply of the first gas GA, the lifting part 7 retracts the plurality of substrate supports MC below a lower surface of the substrate W.SELECTED DRAWING: Figure 1 【課題】基板に供給された処理流体が基板支持部によって跳ね返されることを抑制できる基板処理装置を提供する。【解決手段】基板処理装置100は、スピンベースSBと複数の基板支持部MCとノズル19と昇降部7とチャンバー1とを備える。スピンベースSBは気体供給口45を有する。複数の基板支持部MCは、スピンベースSBに配置され、基板Wと接触することで基板Wを支持する。ノズル19は、複数の基板支持部MCによって支持された基板Wに対して第1処理流体FL1を供給する。気体供給口45は、基板Wの裏面F2とスピンベースSBとの間に第1気体GAを供給することで負圧を発生させて、複数の基板支持部MCが基板Wを支持していない状態において基板WをスピンベースSBに保持させる。第1気体GAの供給によって基板WがスピンベースSBに保持される場合、昇降部7は、複数の基板支持部MCを基板Wの下面よりも下方に退避させる。【選択図】図1
