Abstract:
In one embodiment of the present disclosure, a method for electrochemical deposition on a workpiece includes (a) obtaining a workpiece including a feature; (b) depositing a first conductive layer in the feature; (c) moving the workpiece to an integrated electrochemical deposition plating tool configured for hydrogen radical H* surface treatment and electrochemical deposition; (d) treating the first conductive layer using a hydrogen radical H* surface treatment in a treatment chamber of the plating tool to produce a treated first conductive layer; and (e) maintaining the workpiece in the same plating tool and depositing a second conductive layer in the feature on the treated first conductive layer in an electrochemical deposition chamber of the plating tool.
