Abstract:
1. An apparatus for processing a rotating substrate comprising: an atomizing unit having an atomizing chamber; a first gas passage terminating in an opening into the atomizing chamber for introducing a first gas into the atomizing chamber along a first axis, the opening being formed in a removable set screw that forms a portion of the first gas passage; a cleaning fluid passage for introducing a cleaning fluid into the atomizing chamber along a second axis so that the cleaning fluid combines with the first gas to form a mixture within the atomizing chamber; an acceleration unit operably connected to the atomizing unit, the acceleration unit having an acceleration passage for spraying the mixture formed in the atomizing chamber onto a substrate surface; and wherein the first axis forms a non-zero acute angle with the second axis so that the first gas and the cleaning fluid converge within the atomizing chamber at the non-zero angle.
