    摘要: The methods described are directed to processes for producing structures containing metallized features for use in microelectronic workpieces. The processes treat a barrier layer to promote the adhesion between the barrier layer and the metallized feature. Suitable means for promoting adhesion between barrier layers and metallized features include an acid treatment of the barrier layer, an electrolytic treatment of the barrier layer, or deposition of a bonding layer between the barrier layer and metallized feature. The processes described modify an exterior surface of a barrier layer making it more suitable for electrodeposition of metal on a barrier, thus eliminating the need for a PVD or CVD seed layer deposition process. According to the processes described metallized features are formed on the treated barrier layers using processes that employ ion permeable barriers.

    摘要: Processes and systems for electrolytically processing a microfeature workpiece with a first processing fluid and an anode are described. Microfeature workpieces are electrolytically processed using a first processing fluid, an anode, a second processing fluid, and a cation permeable barrier layer. The cation permeable barrier layer separates the first processing fluid from the second processing fluid while allowing certain cationic species to transfer between the two fluids. The described processes produce deposits over repeated plating cycles that exhibit deposit properties (e.g., resistivity) within desired ranges.
