Abstract:
1. A processing tool, comprising: an ultraviolet processing chamber defining a processing region; a substrate support for supporting a substrate within the processing region; an ultraviolet (UV) radiation source spaced apart from the substrate support and configured to generate and transmit ultraviolet radiation to a substrate positioned on the substrate support; a window disposed between the UV radiation source and the substrate support; a transparent showerhead disposed within the processing region between the window and the substrate support and defining an upper processing region and a lower processing region, the upper processing region located between the window and the transparent showerhead and the lower processing region located between the transparent showerhead and the substrate support, the transparent showerhead having one or more transparent showerhead passages between the upper and lower processing regions; a gas distribution ring having one or more gas distribution ring passages between a gas distribution ring inner channel within the gas distribution ring and the upper processing region; and a gas outlet ring positioned below the gas distribution ring, the gas outlet ring having one or more gas outlet passages between a gas outlet ring inner channel within the gas outlet ring and the lower processing region.
