Abstract:
1. An apparatus for non-contact wet processing, comprising: a source of a liquid material; a reaction cell, wherein the reaction cell is configured for positioning at a selected distance from a surface of a substrate, wherein the reaction cell includes a liquid inlet, the liquid inlet configured to transfer the liquid material from the liquid source to an interior of the reaction cell; a plurality of gas jets disposed within the interior reaction cell, the gas jets configured to atomize the liquid material transferred to the interior of the reaction cell; a vacuum element, the vacuum element disposed along an entire periphery of the reaction cell, the vacuum element configured to evacuate portions of the liquid material at the outer edge of a selected region of the surface of the substrate such that the liquid material that remains on the surface of the substrate is contained within the selected region; and at least one gas curtain element configured to flow a gas at the entire periphery of the reaction cell in order to further contain the liquid material within the selected region of the surface of the substrate.
