Title:
COPPER ELECTRODEPOSITION DEVICE
Document Type and Number:
WIPO Patent Application WO/2020/207480
Kind Code:
A1
Abstract:
The present application discloses a copper electrodeposition device. The copper electrodeposition device comprises a first main beam, a second main beam, a first conductive plate provided on the first main beam, a second conductive plate provided on the second main beam, a plurality of anode plates and a plurality of cathode plates connected to the first main beam and the second main beam, and a plurality of frames respectively located between anode plates and cathode plates adjacent to each other, the plurality of anode plates and the plurality of cathode plates being arranged alternately at intervals, two side faces of the anode plates and the cathode plates being respectively in contact with the first conductive plate and the second conductive plate; the frames are provided with liquid inlet nozzles and liquid outlet nozzles; the plurality of frames are respectively and correspondingly provided between every adjacent anode plate and cathode plate, every adjacent anode plate and cathode plate are pressed tightly together with the frame therebetween, and a closed space is formed between said cathode plate and anode plate. Adjacent anode plates and cathode plates are provided away from each other to facilitate the removal of cathode plates. The copper electrodeposition device in the present application has small electrode spacing and a high degree of parallelism between anode plates and cathode plates.
