A plating apparatus includes a discharge module 50. The discharge module includes a module main body 51 including a plurality of nozzles 52 configured to discharge a process liquid upward, and a moving mechanism 60 including a rotation shaft 61 disposed at a side of a plating tank and connected to the module main body. The moving mechanism 60 moves the module main body by rotation of the rotation shaft. The moving mechanism moves the module main body between the first position and the second position. The plurality of nozzles are arranged such that the process liquid discharged from the plurality of nozzles is brought in contact with a lower surface of a substrate from a center portion to an outer peripheral edge portion when the module main body moves to the second position.

A preprocess is efficiently performed on a substrate. A pre-wet module 200 includes a deaeration tank 210, a processing device 258, a substrate holder 220, and a drive mechanism 230. The deaeration tank 210 is configured to house a deaerated liquid. The processing device 258 includes a nozzle 268 configured to supply a cleaning liquid to a surface to be processed of a substrate having the surface to be processed facing upward. The substrate holder 220 is disposed between the deaeration tank 210 and the processing device 258. The substrate holder 220 includes a first holding member 222 configured to hold a first substrate and a second holding member 224 configured to hold a second substrate. The drive mechanism 230 is configured to rotate and move up and down the substrate holder 220. The drive mechanism 230 includes a rotation mechanism 240 and an elevating mechanism 248. The rotation mechanism 240 is configured to rotate the substrate holder 220 between a first state where a surface to be processed of the first substrate is opposed to a deaerated liquid in the deaeration tank 210 and a second state where a surface to be processed of the second substrate is opposed to the deaerated liquid in the deaeration tank. The elevating mechanism 248 is configured to move up and down the substrate holder 220.

Disclosed are cup assemblies for holding, sealing, and providing electrical power to a semiconductor substrate during electroplating which may include a cup bottom element having a main body portion and a moment arm, an elastomeric sealing element disposed on the moment arm, and an electrical contact element disposed on the elastomeric sealing element. The main body portion may be such that it does not substantially flex when a substrate is pressed against the moment arm, and it may be rigidly affixed to another feature of the cup structure. The ratio of the average vertical thickness of the main body portion to that of the moment arm may be greater than about 5. The electrical contact element may have a substantially flat but flexible contact portion disposed upon a substantially horizontal portion of the sealing element. The elastomeric sealing element may be integrated with the cup bottom element during manufacturing.

A plating module includes: a plating tank, a substrate holder, and an elevating mechanism. The plating tank is for housing a plating solution. The substrate holder is for holding a substrate with a surface to be plated facing downward. The elevating mechanism is for moving up and down the substrate holder. The substrate holder includes: a supporting mechanism, a floating plate, a floating mechanism, and a pushing mechanism. The supporting mechanism is for supporting an outer peripheral portion of the surface of the substrate. The floating plate is arranged on a back surface side of the substrate. The floating mechanism is for biasing the floating plate to a direction away from a back surface of the substrate. The pushing mechanism is for pressing the floating plate to the back surface of the substrate against a biasing force to the substrate by the floating mechanism.
