Claim:
A system for processing microfeature workpieces, comprising: a vessel configured to carry a processing fluid, the vessel having a generally planar process location positioned to receive a microfeature workpiece; a workpiece support positioned to carry a microfeature workpiece at the process location of the vessel; a paddle chamber in fluid communication with the vessel, the paddle chamber having an opening at the process location to receive a microfeature workpiece, the paddle chamber having a base portion facing the process location and being spaced apart from the process location by a first distance along a first axis generally normal to the process location, the paddle chamber further having a plurality of sidewall portions extending downwardly away from the process location, at least one of the sidewall portions including a fluid entrance at least proximate to the process location, and at least one of the sidewall portions further including a fluid exit at least proximate to the process location; and a paddle device disposed in the paddle chamber, the paddle device having at least one paddle positioned between the fluid entrance and the fluid exit, wherein at least one of the workpiece support and the at least one paddle is movable along a generally linear second axis to agitate processing fluid at the process location while the workpiece support carries a microfeature workpiece.
