technical field
[0001] The present invention relates to a positioning device suitable for a standby unit or the like arranged in front of a substrate processing apparatus. Background technique
[0002] Devices disclosed in Patent Document 1 and Patent Document 2 are known as devices for positioning substrates such as semiconductor wafers and glass substrates in a floating state.
[0003] In the device disclosed in Patent Document 1, air is jetted from an air jet opening opened on the stage to float the wafer, and in this state, the wafer is pushed by the air from the air nozzle disposed on one side. Positioning is performed on the reference member provided at the place opposite to the air nozzle. In the device disclosed in Patent Document 2, a suction pad is provided at the corner or the periphery of the frame-shaped workbench, the suction pad is added with an air ejection function, and the photomask (substrate) is blown by the air ejected from the suction pad. ) to float ...
