Abstract:
1. A method of controlling the hydrophobicity of a substrate surface by depositing an oxide upon said substrate surface, where said oxide is formed from at least one precursor in a manner which provides control over a density of hydroxyl groups on said oxide surface during deposition of said oxide onto the substrate surface, wherein said oxide is formed on said substrate surface in a process chamber operated at a pressure within the range of about 0.5 Torr to about 30 Torr, wherein said substrate surface temperature during deposition of said oxide ranges from about 15° C. and about 80° C., wherein a precise, specific quantity of each precursor material is charged to said process chamber in a batch-like manner by adding each precursor material into the process chamber in controlled aliquots, and wherein said oxide is formed by reacting a chlorosilane vaporous precursor having at least two chlorine atoms with a water precursor.
