A processor and method for rinsing and drying of semiconductor substrates includes a process vessel contained within an outer containment vessel. A diluted organic vapor creates a Marangoni effect flow along the surface of processing liquid contained within the process vessel. The process vessel includes porous walls that allow residual chemicals, organic species, and other unwanted materials to flow from the process vessel to the outer containment vessel. The porous walls allow for the maintenance of a stable surface tension gradient to sustain a consistent Marangoni force for even drying. Replacement processing fluid is preferably introduced to the process vessel to prevent the build up of organic species in the surface layer of the processing fluid.
