ABSTRACT:
Method and apparatus for cleaning semiconductor devices and other workpieces using an aqueous rinse solution which is de-oxygenated and hydrogen enriched by passing the aqueous rinse solution and a treatment fluid through an osmotic membrane degasifier. In the preferred embodiment, only a single component, forming gas, is employed to provide both functions of oxygen removal and hydrogen injection.
