A fluid delivery module for use in preparing a substrate is provided. The fluid delivery module includes a process bowl designed to contain a substrate to be prepared. The process bowl has a bottom wall and a sidewall. The fluid delivery module further includes a fluid delivery ring configured to be attached to the sidewall of the process bowl. The fluid delivery ring includes a plurality of inlet and outlet pairs. Each of the plurality of inlet and outlet pairs is defined in the fluid ring and is designed to receive a respective supply tube. Each respective supply tube has an end that terminates at each of the outlets of the fluid delivery ring and is configured to direct fluid onto a surface of the substrate.

The invention claimed is: 1. A method for making a fluid delivery ring, the method comprising: generating a solid ring having a side surface, a top surface, and an under surface; forming a plurality of slots into the under surface of the solid ring, each of the plurality of slots extending into the
The invention claimed is: 1. A method for making a fluid delivery ring, the method comprising: generating a solid ring having a side surface, a top surface, and an under surface; forming a plurality of slots into the under surface of the solid ring, each of the plurality of slots extending into the solid ring and defining a sidewall proximate to the side surface and a topwall proximate to the top surface; and generating inlet holes and outlet holes at each of the plurality of slots, the inlet holes being defined into an intersection of the sidewall and the under surface and the outlet holes being defined into an intersection of the topwall and the under surface, wherein respective inlet holes, outlet holes and slots are configured to define paths for delivering a fluid to a region within the fluid delivery ring. 2. The method of claim 1, further comprising: defining the solid ring from a chemically inert material. 3. The method of claim 1, wherein a top side surface is a downwardly sloped surface that defines a delivery projection of the fluid to be supplied by the fluid delivery ring. 4. The method of claim 1, wherein the outlet holes are arranged in a ring orientation at the intersection of the topwall and the under surface of the fluid delivery ring such that the diameter of the ring is larger than the diameter of the substrate to be prepared. 5. A method for making a fluid delivery ring, the method comprising: generating a solid core ring having a side surface, a top surface, and an under surface; forming a plurality of guiding channels within the solid core ring, each of the plurality of guiding channels extending through the solid core ring; and generating inlet holes and corresponding outlet holes at each of the plurality of guiding channels, the inlet holes being defined into an intersection of the sidewall and the under surface and the corresponding outlet holes being defined into an intersection of the topwall and the under surface such that each inlet hole is opposed by the corresponding outlet hole, wherein respective inlet holes, corresponding outlet holes, and guiding channels are configured to define paths for delivering a fluid to a region within the fluid delivery ring. 6. The method of claim 5, wherein the plurality of guiding channels is formed in equal distances around the solid core ring. 7. The method of claim 6, wherein eight (8) guiding channels are formed in equal distances around the solid core ring. 8. The method of claim 5, wherein the paths deliver different types of fluid to the region within the fluid delivery ring. 9. The method of claim 5, wherein the paths deliver a same type of fluid to the region within the fluid delivery ring. 10. A method for making a fluid delivery ring, the method comprising: generating a solid ring having a side surface, a top surface, and an under surface; generating inlet holes and opposing outlet holes in the solid ring, the inlet holes being defined into an intersection of the sidewall and the under surface and the opposing outlet holes being defined into an intersection of the topwall and the under surface, and forming a plurality of conduits into the solid ring between each pair of inlet hole and opposing outlet hole, each of the plurality of conduits extending through the solid ring. 11. A method as recited in claim 10, wherein respective inlet holes, outlet holes, and conduits are configured to define paths for delivering a fluid to a region within the fluid delivery ring. 12. A method as recited in claim 11, further comprising: defining the solid ring from a chemically inert material. 13. The method of claim 10, wherein a top side surface is a downwardly sloped surface that defines a delivery projection of the fluid to be supplied by the fluid delivery ring. 14. The method of claim 10, wherein the outlet holes are arranged in a ring orientation at the intersection of the topwall and the under surface of the fluid delivery ring such that the diameter of the ring is larger than the diameter of the substrate to be prepared.
