ABSTRACT:
Oxidic surfaces can be chemically modified according to a pattern by providing one or several monolayers of a photosensitive silane. After patterned exposure of said photosensitive silane, the exposed pans are esterified with an alcohol which comprises at least one fluorine atom, so that said exposed areas become strongly hydrophobic. Subsequently, the unexposed areas are exposed, so that these areas become hydrophilic. The hydrophilic areas can then be metallized in an electroless process, thereby forming a metal pattern.
