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 8):
A method for electroplating a wafer, the method comprising:\n submerging the wafer in a first bath reservoir containing a first electrolyte solution, the first electrolyte solution comprising an alkaline copper-complexed solution, the wafer comprising features deposited with a cobalt layer; electroplating the wafer with a first layer of copper on the cobalt layer by applying electrical pulses to the wafer and a first anode disposed in the first electrolyte solution; removing the wafer from the first bath reservoir and submerging the wafer in a second bath reservoir containing a second electrolyte solution, the second electrolyte solution comprising an acidic copper-plating solution; and electroplating the wafer with a second layer of copper on the first layer of copper by applying electrical pulses to the wafer and a second anode disposed in the second electrolyte solution.
