Claim:
1. An apparatus for rinsing and drying a substrate, comprising: a body defining a volume configured to accommodate a semiconductor substrate; one or more reservoir members comprising a weir, the one or more reservoir members coupled to one or more rinse fluid sources and to the body having a substrate passage disposed therethrough, wherein the substrate passage is sized to allow passage of a substrate, the substrate passage allowing the reservoir members to provide a waterfall of rinse fluid from the one or more rinse fluid sources through the substrate passage into a lower portion of the volume; a plurality of nozzles positioned to provide rinse fluid for coverage across an area of the substrate below the one or more reservoir members; a plurality of solvent spray members positioned to provide a drying agent above the one or more reservoir members, and a fluid collection member spaced from the body and below the body and extending outward beyond the body such that the volume is open to a region external to the body and rinse fluid does not collect in the volume, wherein the fluid collection member is adapted to collect rinse fluid that flows over the weir and rinse fluid that flows through the substrate passage.
