Abstract:
Embodiments of the invention generally provide a fluid delivery system for an electrochemical plating platform. The fluid delivery system is configured to supply multiple chemistries to multiple plating cells with minimal bubble formation in the fluid delivery system. The system includes a solution mixing system, a fluid distribution manifold in communication with the solution mixing system, a plurality of fluid conduits in fluid communication with the fluid distribution manifold, and a plurality of fluid tanks, each of the plurality of fluid tanks being in fluid communication with at least one of the plurality of fluid conduits.
Abstract:
Embodiments of the invention generally provide an electrochemical plating system. The plating system includes a substrate loading station positioned in communication with a mainframe processing platform, at least one substrate plating cell positioned on the mainframe, at least one substrate bevel cleaning cell positioned on the mainframe, and a stacked substrate annealing station positioned in communication with at least one of the mainframe and the loading station, each chamber in the stacked substrate annealing station having a heating plate, a cooling plate, and a substrate transfer robot therein.
Abstract:
A method for cleaning the electrical contact areas or substrate contact areas of an electrochemical plating contact ring is provided. Embodiments of the method include positioning a substrate on a substrate support member having one or more electrical contacts, chemically plating a metal layer on at least a portion of a surface of the substrate, removing the processed substrate from the support member, and cleaning the one or more electrical contacts with a vapor mixture comprising an alcohol. In another aspect, the method includes spraying the vapor mixture on the electrical contacts while rotating the substrate support member.
Abstract:
A system is provided in which a smaller flow of deposition solution is diverted from a larger flow of deposition solution flowing on an electrochemical deposition tool platform. The smaller flow is diverted to a dosing unit which may be on a separate platform. The dosing unit in one embodiment comprises a pressurized flow line.
