Carrier liquid leakage preventing device and electrochemical deposition apparatus

A carrier liquid leakage preventing device for containing liquid dripping from a carrier;

• wherein the carrier liquid leakage preventing device comprises:
• a guide rail disposed along a first direction, said first direction being a vertical direction perpendicular to the horizontal plane or a direction at an angle to the horizontal plane;
• a leakage preventing groove provided on the guide rail and capable of performing a lifting movement along the guide rail so as to move above or below the carrier;
• and
• a driver for driving the lifting movement of the leakage preventing groove,
• wherein the carrier comprises two opposite sides, and at least one of the two opposite sides is a bearing surface for bearing a substrate;
• and the leak preventing groove comprises at least a first part and a second part separated from each other by a predetermined distance so as to be respectively located on two opposite sides of the carrier;
• or, the first part and the second part are combined to form a channel structure with an opening facing upwards,
• the first part comprises a first baffle structure and the second part comprises a second baffle structure, and the first baffle structure and the second baffle structure each comprises a top end and a bottom end;
• and the first baffle structure and the second baffle structure are arranged in parallel and spaced apart, or the bottom ends of the first baffle structure and the second baffle structure are connected together to form a V-shaped groove structure;
• wherein the bottom end of the first baffle structure is provided with a first magnetic component;
• the bottom end of the second baffle structure is provided with a second magnetic component;
• and the first magnetic component and the second magnetic component cooperate with each other to interconnect or separate the bottom end of the first baffle structure and the bottom end of the second baffle structure.
