A method of processing a substrate comprising a) supporting a substrate having a hydrophilic surface in a substantially horizontal orientation, b) rotating the substrate, c) applying a film of an aqueous solution of HF to the hydrophilic surface of the substrate for a period of time sufficient to convert the hydrophilic surface into a hydrophobic surface, wherein the concentration of HF is between about 0.1% to about 0.5% by weight of HF in water and the period of time is between about 100 and about 300 seconds, d) applying DI water to the hydrophobic surface of the substrate, and e) applying a drying fluid to the hydrophobic surface of the substrate so as to substantially dry the hydrophobic surface. The invention also is an apparatus for processing a substrate comprising a chamber having at least one wall, a rotary support member located within the chamber for supporting the substrate in a substantially horizontal position and adapted to rotate the substrate, and a first exhaust exit located within the at least one wall, wherein the first exhaust exit is tangential to a rotational direction of the substrate.
