Hydrofluoric acid (HF) mixed with water and often buffered with ammonium fluoride is a standard silicon dioxide wet etchant which is followed by a rinse. An improved silicon dioxide etch is vapor HF which may be followed by a water vapor rinse. The invention discloses a further improved silicon dioxide etch. Following an initial exposure to vapor HF for oxide removal, a first insitu water rinse occurs. A second exposure to vapor HF then occurs and is followed by a second insitu water rinse. Water, rather than water vapor, aids in freeing particles from the wafer surface.

The process may be practiced in a commercially available reactor and is suitable for ULSI devices having complex topographies, such as, for example, 64 megabit DRAMs employing crown type memory cells.
