An embodiment of the present invention provides a buff process module. The buff process module includes: a buff table on which a processing target object is mounted; a buff head that holds a buff pad for applying a predetermined process to the processing target object; a buff arm that supports and swings the buff head; a dresser for dressing the buff pad; and a cleaning mechanism that is disposed between the buff table and the dresser and is for cleaning the buff pad.

Substrate processing apparatus

A sensor target cover capable of preventing an optical liquid level detection sensor from erroneously detecting a rise in a liquid level is provided. A sensor target cover is used in combination with an optical liquid level detection sensor. The sensor target cover includes a reflecting plate, an inner wall structure surrounding the reflecting plate, and an outer wall structure surrounding the inner wall structure. A gap is formed between the inner wall structure and the outer wall structure.

An object of the present invention is to detach a substrate from a table without damaging the substrate by lift pins. One embodiment of the present invention provides a substrate processing apparatus having a vacuum suction table adapted to have a substrate placed thereon, and a plurality of lift pins disposed along the outer periphery of the vacuum suction table. The lift pins each have a distal end portion including a substrate guide surface capable of guiding the outer peripheral end surface of the substrate, and a proximal end portion including a substrate holding surface extending from the substrate guide surface outwardly in a radial direction of the lift pin. The lift pins are stoppable in a lower end position where the substrate guide surface of each of the lift pins is disposed below a suction-holding surface of the vacuum suction table, an upper end position where the substrate holding surface of each of the lift pins is disposed above the suction-holding surface of the vacuum suction table, and an intermediate position between the lower end position and the upper end position. In the intermediate position, the substrate guide surface of each of the lift pins is disposed above the suction-holding surface of the vacuum suction table, and the substrate holding surface of each of the lift pins is disposed below the suction-holding surface of the vacuum suction table.

A substrate holding apparatus that can minimize a deflection amount of a substrate due to its own weight and can suppress vibration of the substrate at the time of rotation of the substrate even if a diameter of the substrate becomes large is disclosed. The substrate holding apparatus holds a periphery of a substrate and rotates the substrate. The substrate holding apparatus includes a plurality of support posts supported by a base and vertically movable relative to the base, a plurality of chucks respectively provided on the plurality of support posts and configured to hold the periphery of the substrate, and at least one support pin configured to support a lower surface of the substrate held by the plurality of chucks.

Substrate holding apparatus

A substrate processing apparatus including: a first valve provided between a gas supply source and an air-water separation tank, the first valve opening and closing a flow path of a gas supplied from the gas supply source; a second valve that opens and closes a flow path of liquid discharged from a discharge port of the air-water separation tank; and a control unit that controls the first valve and the second valve. The discharge port of the air-water separation tank communicates with a discharge port of a cleaning chamber that cleans the substrate, and the control unit controls to close the first valve after preset gas supply time elapses from when the first valve is opened and gas can no longer be discharged from the air-water separation tank and controls to close the second valve after the first valve is closed.

Substrate processing apparatus, discharge method, and program

There is disclosed an improved substrate holding apparatus which can minimize deformation of a spring, which is provided to bias a support post for supporting a substrate, even when a large centrifugal force acts on the spring. The substrate holding apparatus includes: a support post movable in an axial direction thereof; a chuck provided on the support post and configured to hold a periphery of a substrate; a spring biasing the support post in the axial direction; a first structure configured to restrict a movement of an upper portion of the spring in a direction perpendicular to the axial direction of the support post; and a second structure configured to restrict a movement of a lower portion of the spring in a direction perpendicular to the axial direction of the support post.

A substrate processing apparatus has a substrate rotating devicefor holding and rotating a substrate W, a cleaning deviceconfigured to clean a substrate W which is rotated by the substrate rotating deviceat predetermined rotating speed, a movement deviceconfigured to move the cleaning devicebetween a cleaning position Pand a separate position P, and a control unit. The control unitcontrols the movement deviceso that the cleaning devicelocated at the separate position Pstarts moving toward the cleaning position Pbefore a rotating speed of the substrate W held by the substrate rotating devicereaches the predetermined rotating speed and the cleaning devicereaches the cleaning position Pafter a rotating speed of the substrate W reaches the predetermined rotating speed. Therefore, it is possible to improve the throughput in the substrate cleaning step.
