Abstract: A two-piece chuck for supporting a substrate in which a base plate allows the wafer to tilt and also exposes the underside of the wafer during wash/rinse cycle as well as during load/unload operations.

Abstract: A multiple station processing chamber used to deposit and/or remove a material on a semiconductor wafer is described. The multiple station processing chamber is comprised of two or more processing stations at which the wafer is exposed to a processing fluid. The processing stations are positioned within the chamber such that the wafer may be moved from station to station while remaining within the chamber. Each station of the multiple station processing chamber may have a fluid containment ring used for containment, disposal, and/or reuse of the electrolyte used to process the wafer at that particular processing station. The wafer is brought to the first processing station on a wafer support and exposed to a first processing fluid, which is then diverted into fluid containment ring for the first processing station. The wafer is then moved to a second processing chamber where the process is repeated with a second processing fluid.

Abstract: A fluid containment ring for use in a processing chamber used to deposit a material onto a semiconductor wafer and/or remove material from a wafer by subjecting the wafer to an electric field and an electrolyte is described. The fluid containment ring is located at the base of the processing chamber in close proximity to the outside edge of the wafer being processed in the processing chamber. After each processing step is completed, the used electrolyte is diverted from the processing chamber into the fluid containment ring for containment such that no electrolyte contacts the unprocessed side (or back) of the wafer. One or more drains coupled to the fluid containment ring provide means for disposal and/or recirculation of the electrolyte.

Abstract: A processing chamber for depositing and/or removing material onto/from a semiconductor wafer when the wafer is subjected to an electrolyte and in an electric field, and in which the electrolyte is introduced and/or evacuated from a closely confined containment region. A hollow sleeve is utilized to form a containment chamber for holding the electrolyte. A wafer residing on a support is moved vertically upward to engage the sleeve to form an enclosing floor for the containment chamber. One electrode is disposed within the containment chamber while the opposite electrode is comprised of several electrodes distributed around the circumference of the wafer. The electrodes are also protected from the electrolyte when the support is raised and engaged to the sleeve. In one embodiment, the support and the sleeve are stationary during processing, while in another embodiment, both are rotated or oscillated during processing.

Abstract: An apparatus and method for customizing electrode contact placement on a semiconductor wafer while depositing and/or removing a material on a semiconductor wafer. The present invention is a adapter having at least one opening through which at least one electrode contacts the semiconductor wafer. The adapter may be designed to have multiple openings at specified locations on the adapter, thus allowing multiple electrode contacts with the semiconductor wafer at pre-specified locations. A conductive sheet may couple with the adapter to carry an electrical current from an electrical conductor to the electrode contacts placed within the openings of the adapter.

Abstract: An apparatus and method for providing an integrated processing system allowing for the isolation of non-compatible processes used to deposit a material onto a semiconductor wafer and/or remove material from a wafer is described. The integrated processing system of the present invention is comprised of a first processing chamber for processing a substrate in a first environment coupled to a second processing chamber for processing a substrate in a second environment. A connecting interface coupled to the first and second processing chambers allows the first and second processing chambers to be isolated from each other as needed. Further, the connecting interface allows a wafer to be transferred from the first processing chamber to the second processing chamber within a controlled environment. The first and second processing chambers may be or may include cluster tools.

Abstract: A copper replenishment system for replenishing copper which is depleted from a copper plating solution. The replenishment is achieved by the use of a compact filter cartridge, which is inserted into a recirculating loop for the solution. The filter cartridge contains a chemical, which when reacting with the solution replenishes the copper into the solution. The filter cartridge is a compact unit which can be easily handled and reduces the amount of contaminants that could be introduced by the presence of the replenishment chemical.
