This invention is directed to an improvement in a wet chemical process for producing electronic precursors. In such process a silicon surface is treated with a wet chemical and the wet chemical subsequently removed therefrom by contact with a drying vapor. In this case, the improvement in the process comprises: employing a drying vapor comprised of isopropanol; and, maintaining the isopropanol employed in said drying vapor at a temperature below about 80° F. prior to forming said drying vapor. Preferably the isopropanol is maintained free from exposure to light from the time of manufacture to the time of use.
