A workpiece processor has a process chamber for holding a liquid. A sonic element, such as a megasonic transducer, is positioned to provide sonic energy into the liquid. A workpiece holder is moveable from a first position, wherein a workpiece is held immersed in the liquid, for sonic processing, to a second position where the workpiece is generally aligned with spray nozzles. Process liquids and gases may be sprayed or otherwise provided onto the workpiece, optionally while the workpiece is rotating within the process chamber. A process chamber gas or vapor exhaust assembly prevents escape of process gases or vapors from the processor. The processor can provide both sonic processing, as well as liquid and/or gas chemical processing.
