Abstract:
1. A method for cleaning a substrate, comprising: providing a cleaning assembly comprising: a bottom cleaning module for performing a spin-rinse-dry operation on a substrate, the bottom cleaning module having a base portion housing a chuck for receiving the substrate; a top cleaning module disposed over the bottom cleaning module, wherein a mid-portion of the cleaning assembly is operable to be a base of the top cleaning module and a top of the bottom cleaning module; a component located in the bottom cleaning module for applying a cleaning chemistry onto a top surface of the substrate; and a port located in the bottom cleaning module below a bottom surface of the substrate and operably connected to a vacuum source for exhausting vapors from the cleaning chemistry; transferring the substrate to the bottom cleaning module; applying the cleaning chemistry onto a top surface of the substrate, wherein the cleaning chemistry is at a temperature higher than ambient temperature; concurrent with introducing the cleaning chemistry, exhausting vapors from the cleaning chemistry through the port located in the bottom cleaning module; terminating application of the cleaning chemistry; terminating the exhausting of the vapors upon terminating the application of the cleaning chemistry; and drying the substrate after terminating the application of the cleaning chemistry.
