Abstract:
While a substrate is being rotated, the lower surface of a brush is moved along the upper surface of the substrate. The brush and a spray nozzle are moved upward from a takeoff position to a lower non-contact position so as to separate the lower surface of the brush from the upper surface of the substrate. The spray nozzle generates the droplets in a state where the brush and the spray nozzle are located in the lower non-contact position so as to make the droplets collide with the upper surface of the substrate, and then the droplets colliding with the upper surface of the substrate are discharged from a gap between the lower surface of the brush and the upper surface of the substrate while the droplets are being supplied to the lower surface of the brush.

Claim (Index 1):
A substrate processing method performed by a substrate processing apparatus including: a brush which includes a lower surface that is pressed against an upper surface of a substrate held horizontally, a central opening that is open in a central portion of the lower surface and a nozzle insertion hole that is extended upward from the central opening; and a spray nozzle which is inserted into the nozzle insertion hole and which generates a plurality of droplets that are scattered toward the upper surface of the substrate through the central opening, the substrate processing method comprising:\n a brush landing step of moving the brush and the spray nozzle downward to a landing position in which the lower surface of the brush comes into contact with the upper surface of the substrate; a scrub cleaning step of moving the brush and the spray nozzle from the landing position to a takeoff position in a horizontal radial direction orthogonal to a vertical rotation axis passing through a central portion of the substrate while rotating the substrate about the rotation axis so as to move the lower surface of the brush along the upper surface of the substrate; a brush takeoff step of moving the brush and the spray nozzle upward from the takeoff position to a lower non-contact position so as to separate the lower surface of the brush from the upper surface of the substrate; and a takeoff spray step of making the spray nozzle generate the droplets in a state where the brush and the spray nozzle are located in the lower non-contact position so as to make the droplets collide with the upper surface of the substrate, and then discharging the droplets colliding with the upper surface of the substrate from a gap between the lower surface of the brush and the upper surface of the substrate while supplying the droplets that have collided with the upper surface of the substrate to the lower surface of the brush.
