Abstract:
1. A rinse solution nozzle assembly for dispensing a rinse solution on a substrate, comprising: a first nozzle array including one nozzle disposed on a central axis extending normally from a center of the substrate, and configured to dispense said rinse solution substantially near the center of said substrate; a first control valve coupled to said first nozzle array and configured to actuate a first flow rate of said rinse solution through said first nozzle array; a second nozzle array including a plurality of nozzles, said nozzles arranged at fixed positions along a radial span aligned with the central axis and extending from near center of the substrate toward a perimeter of the substrate and configured to dispense said rinse solution across the radial span on a side of the substrate facing the first nozzle array; a second control valve coupled to said second nozzle array and configured to actuate a second flow rate of said rinse solution through said second nozzle array; and a fluid supply line connecting a rinse solution supply to both the first control valve and the second control valve and supplying the rinse fluid solution through the fluid supply line both to the first control valve and to the second control valve for supply of the same rinse solution to both the first nozzle array and the second nozzle array.
