Summary: | To provide a substrate processing apparatus capable of cleaning the back surface of a substrate with a strong pressure while suppressing damage to the substrate.SOLUTION: A substrate processing apparatus 100 includes a spin base SB, a plurality of chuck pins 37, a cleaning mechanism 10, and a lift pin 35. The cleaning mechanism 10 is arranged above the substrate W and physically cleans the back surface Wb of the substrate W. The plurality of chuck pins 37 have contact surfaces 372a and opposing surfaces 371a. The contact surface 372a contacts the substrate W when the substrate W is gripped. The opposing surface 371a extends in a direction intersecting the vertical direction from the lower end of the contact surface 372a. The opposing surface 371a faces the front surface Wa of the substrate W. The opposing surface 371a is adjacent to the upper surface Ra1 of the peripheral edge portion Ra of the spin base SB and is arranged at substantially the same height as the upper surface Ra1 of the peripheral edge portion Ra of the spin base SB. The spin base SB has a gas ejection port 33e for ejecting gas on its upper surface.SELECTED DRAWING: Figure 7
【課題】基板が損傷することを抑制しながら、基板の裏面を強い圧力で洗浄することが可能な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、複数のチャックピン37と、洗浄機構10と、リフトピン35とを備える。洗浄機構10は、基板Wの上方に配置され、基板Wの裏面Wbを物理的に洗浄する。複数のチャックピン37は、当接面372aと、対向面371aとを有する。当接面372aは、基板Wを把持する際に基板Wに当接する。対向面371aは、当接面372aの下端から鉛直方向に対して交差する方向に延びる。対向面371aは、基板Wの表面Waに対向する。対向面371aは、スピンベースSBの周縁部Raの上面Ra1に隣接し、且つ、スピンベースSBの周縁部Raの上面Ra1と略同じ高さに配置される。スピンベースSBは、気体を吐出するガス吐出口33eを上面に有する。【選択図】図7 |
