发明名称 Apparatus and method for agitating liquids in wet chemical processing of microfeature workpieces
摘要 Reactors with agitators and methods for processing microfeature workpieces with such reactors. The agitators are capable of obtaining high, controlled mass-transfer rates that result in high quality surfaces and efficient wet chemical processes. The agitators generate high flow velocities in the fluid and contain the high energy fluid proximate to the surface of the workpiece to form high quality surfaces when cleaning, etching and/or depositing materials to/from a workpiece. The agitators also have short stroke lengths so that the footprints of the reactors are relatively small. As a result, the reactors are efficient and cost effective to operate. The agitators are also designed so that electrical fields in the processing solution can effectively operate at the surface of the workpiece.
