Abstract:
In one example, an electroplating system comprises a first bath reservoir, a second bath reservoir, a clamp, a first anode in the first bath reservoir, a second anode in the second bath reservoir, and a direct current power supply. The first bath reservoir contains a first electrolyte solution that includes an alkaline copper-complexed solution. The second bath reservoir contains a second electrolyte solution that includes an acidic copper plating solution. The direct current power supply generates a first direct current between the clamp and the first anode to electroplate a first copper layer on the cobalt layer of the wafer submerged in the first electrolyte solution. The direct current power supply then generates a second direct current between the clamp and the second anode to electroplate a second copper layer on the first copper layer of the wafer submerged in the second electrolyte solution.

Claim (Index 1):
An electroplating system comprising:\n a first bath reservoir for containing a first electrolyte solution, the first electrolyte solution comprising an alkaline copper-complexed solution; a second bath reservoir for containing a second electrolyte solution, the second electrolyte solution comprising an acidic copper plating solution; a clamp for holding a wafer and submerging the wafer in the first electrolyte solution, removing the wafer from the first electrolyte solution, and submerging the wafer in the second electrolyte solution after the first electrolyte solution, the wafer comprising features deposited with a cobalt layer; a first anode submerged in the first electrolyte solution; a second anode submerged in the second electrolyte solution; and a direct current power supply for generating a first direct current between the clamp and the first anode and for electroplating a first copper layer on the cobalt layer of the wafer in the first electrolyte solution, and a second direct current between the clamp and the second anode and for electroplating a second copper layer on the first copper layer of the wafer in the second electrolyte solution.
