Methods and systems are provided which are adapted to process a microelectronic topography, particularly in association with an electroless deposition process. In general, the methods may include loading the topography into a chamber, closing the chamber to form an enclosed area, and supplying fluids to the enclosed area. In some embodiments, the fluids may fill the enclosed area. In addition or alternatively, a second enclosed area may be formed about the topography. As such, the provided system may be adapted to form different enclosed areas about a substrate holder. In some cases, the method may include agitating a solution to minimize the accumulation of bubbles upon a wafer during an electroless deposition process. As such, the system provided herein may include a means for agitating a solution in some embodiments. Such a means for agitation may be distinct from the inlet/s used to supply the solution to the chamber.

What is claimed is: 1. A microelectronic topography process chamber, comprising: a substrate holder; at least two outer enclosure components configured to couple with each other and form a first enclosed area about and including the substrate holder; at least two inner enclosure components comprising a lower enclosure component spaced below the substrate holder and an upper enclosure component spaced above the substrate holder, wherein the inner enclosure components are configured to couple with each other and form a second sealed enclosed area about and including the substrate holder within the first enclosed area; and a means for spinning the upper enclosure component. 2. The microelectronic topography process chamber of claim 1, wherein the microelectronic topography process chamber is adapted to couple the inner enclosure components prior to an electroless deposition process and uncouple the inner enclosure components subsequent to the electroless deposition process. 3. The microelectronic topography process chamber of claim 1, wherein the microelectronic topography process chamber is adapted to: perform a succession of different process steps within the process chamber, wherein each of the different process steps are adapted to process a substrate surface for fabrication of a microelectronic device; couple the outer enclosure components prior to the succession of the different process steps; couple the inner enclosure components prior to performing at least one process step of the different process steps; and uncouple the inner enclosure components prior to performing one or more other process steps of the different process steps without uncoupling the outer enclosure components. 4. The microelectronic topography process chamber of claim 3, wherein the microelectronic topography process chamber is further adapted to uncouple the outer enclosure components for a drying process of the microelectronic topography. 5. The microelectronic topography process chamber of claim 3, wherein the microelectronic topography process chamber is further adapted to dispense different processing fluids into the first and second enclosed areas during the different process steps. 6. The microelectronic topography process chamber of claim 5, wherein the microelectronic topography process chamber comprises: a first outlet within one of the outer enclosure components; and a second outlet within one of the inner enclosure components. 7. The microelectronic topography process chamber of claim 6, wherein the microelectronic topography process chamber is adapted to prevent processing fluids in the first enclosed area from entering the second outlet. 8. The microelectronic topography process chamber of claim 7, wherein the microelectronic topography process chamber comprises a means for spinning the substrate holder. 9. The microelectronic topography process chamber of claim 5, wherein a means for dispensing the different process fluids comprises an inlet positioned below the substrate holder and configured to project one or more of the different process fluids toward a region above the substrate holder. 10. The microelectronic topography process chamber of claim 5, further comprising a device configured to move within the second enclosed area to agitate one or more of the different processing fluid. 11. A microelectronic topography process chamber, comprising: a substrate holder; a means for sealing peripheral walls of the microelectronic topography process chamber to form a first enclosed area about and including the substrate holder; a set of enclosure components arranged within the peripheral walls and configured to couple with each other to form a second distinct sealed enclosed area about and including the substrate holder, wherein the microelectronic topography process chamber is adapted to dispense different processing fluids into the first and second enclosed areas during a succession of different process steps, wherein each of the different process steps are adapted to process a substrate surface for fabrication of a microelectronic device, wherein a lower enclosure component of the set of enclosure components comprises an outlet, and wherein the microelectronic topography process chamber is adapted to prevent processing fluids in the first enclosed area from entering the outlet; and a device configured to move within the second enclosed area to agitate one or more of the different processing fluids. 12. The microelectronic topography process chamber of claim 11, further comprising a means for spinning an upper enclosure component of the set of enclosure components. 13.
