20090080879 | APPARATUS FOR AND METHOD OF PROCESSING SUBSTRATE - A substrate processing apparatus discharges a hydrofluoric acid solution from discharge nozzles toward grooves formed in side walls of an inner bath. The hydrofluoric acid solution discharged from the discharge nozzles impinges upon the grooves to diffuse, thereby moving toward a top portion of the inner bath in the form of low-speed uniform liquid flows. Thus, a metal component and foreign substances generated in the inner bath float up toward the top portion of the inner bath without being agitated within the inner bath, and are rapidly drained to an outer bath together with the hydrofluoric acid solution. | 03-26-2009 |
20090239384 | SUBSTRATE PROCESSING APPARATUS AND SUBSTRATE PROCESSING METHOD - A discharge hole of a lower nozzle is directed at an angle of 5 degrees to 40 degrees slanting inward with respect to a normal to the upper surface of a bottom plate. Thus, the flow pressure of a processing solution discharged through the discharge hole is not excessively reduced. Further, a circulation area of the processing solution does not expand widely in an inner bath. As a result, the processing solution in the inner bath is effectively displaced while the processing solution smoothly flows into gaps between substrates. | 09-24-2009 |
20120199555 | SUBSTRATE PROCESSING APPARATUS AND SUBSTRATE PROCESSING METHOD - A substrate processing apparatus includes a high-speed supply system having a relatively small opening for ejecting a processing liquid through the relatively small opening to supply the processing liquid into a processing bath, and a low-speed supply system having a relatively large opening for ejecting the processing liquid through the relatively large opening to supply the processing liquid into the processing bath. While an etching process is in progress, the processing liquid is supplied through the high-speed supply system. This decreases a difference in concentration of a liquid chemical component in the processing liquid within the processing bath to improve the uniformity of the etching process. While the etching process is not in progress, on the other hand, the processing liquid is supplied through the low-speed supply system. This improves the efficiency of the replacement of the processing liquid within the processing bath. | 08-09-2012 |
