A substrate processing apparatus includes a connection portion connected to the common piping and having a flow space in its interior, a chemical liquid supplying piping connected to the connection portion, a drain piping connected to the connection portion, and a cleaning liquid supplying piping connected to the connection portion, the connection portion has a plurality of ports aligned along a flow direction of the flow space, and a common port, which, among these ports, is connected to one end of the common piping, is disposed, in regard to the flow direction, between a drain port, which, among these ports, is connected to the drain piping, and a cleaning liquid supplying port, which, among these ports, is connected to the cleaning liquid supplying piping.

Substrate processing apparatus

A substrate processing method includes the steps of: rotating a substrate horizontally around a vertical rotational axis, placing a facing member facing the substrate from above such that an inner peripheral surface of an extension portion of the facing member faces the substrate radially from the outside, rotating the facing member around the rotational axis, supplying a processing liquid to an upper surface of the substrate being in a rotated state, and placing a guard that surrounds the substrate further radially outside from the extension portion in plan view at a height position, at which processing liquid scattered from the upper surface of the substrate toward the outside in the radial direction is received by the guard, in accordance with affinity of the processing liquid for the inner peripheral surface of the extension portion.

Substrate treatment method and substrate treatment device

A substrate processing apparatus includes a substrate holder that holds a substrate, a processing liquid piping that is communicatively connected with a discharge port for discharging a processing liquid, a processing liquid supplier that supplies the processing liquid to the processing liquid piping, a suction unit for suctioning the processing liquid present inside the processing liquid piping, and a controller which controls the processing liquid supplying unit and the suction unit. The controller executes a processing liquid supplying step that supplies the processing liquid to the processing liquid piping and a suctioning step that suctions the processing liquid inside the processing liquid piping by the suction unit. The controller selectively executes a first suctioning step and a second suctioning step of the processing liquid.
