There is an apparatus for cleaning a substrate () mounted on a moveable platen. In an example embodiment, the apparatus comprises a first chamber (), the first chamber has solvent-dispensing nozzles (); the solvent-dispensing nozzles wet the substrate surface () with a solvent () as the platen transports the substrate. The platen moves in a predetermined direction and at a predetermined scan velocity as it transports the substrate into a process chamber. The process chamber has a hot source () at a predetermined height (h) from the substrate surface (); it provides heat energy directed toward the substrate surface, the heat energy evaporates the solvent () dispensed on the substrate surface; the solvent evaporation removes particulates () from the substrate surface, as the platen transports the substrate from the first chamber () into the process chamber. Substrates cleaned may include precision photo-masks, or wafers.
