Materials and methods for modifying semiconducting substrate surfaces in order to dramatically change surface energy are provided. Preferred materials include perfluorocarbon molecules or polymers with various functional groups. The functional groups (carboxylic acids, hydroxyls, epoxies, aldehydes, and/or thiols) attach materials to the substrate surface by physical adsorption or chemical bonding, while the perfluorocarbon components contribute to low surface energy. Utilization of the disclosed materials and methods allows rapid transformation of surface properties from hydrophilic to hydrophobic (water contact angle 120° and PGMEA contact angle) 70°. Selective liquiphobic modifications of copper over Si/SiOx, TiOx over Si/SiOx, and SiN over SiOx are also demonstrated.
