Abstract:
An ozone shower system, comprising:an ozone source configured to supply ozone to a process chamber; at least one semiconductor workpiece positioned within a cassette, the cassette having a top and a bottom; at least two rotating axles within the process chamber, the two rotating axles positioned to support the semiconductor workpiece in a manner that creates a gap between the semiconductor workpiece and the bottom of the cassette so that the cassette can remain stationary while the rotating axles rotate the semiconductor workpiece; a sprayer positioned above the top of the cassette, the sprayer connected to a fluid source such that fluid sprays over the semiconductor workpieces in the process chamber; a pump connected to a fluid source; and a selector valve connected to the pump, the selector valve configured to selectively pulse the fluid through the sprayer.
