Abstract:
A hydrophobic dielectric film produced by a process comprising the steps of reacting a suitable hydrophilic silica film with an effective concentration of a surface modification agent, wherein said silica film is present on a substrate and wherein said reaction is conducted under suitable conditions and for a period of time sufficient for said surface modification agent to produce a treated silica film that is substantially hydrophobic, wherein said surface modification agent is multifunctional and wherein said surface modification agent is a compound having a formula selected from the group consisting of R.sub.1 Si(NR.sub.2 R.sub.3).sub.3 ; R.sub.1 Si(ON.dbd.CR.sub.2 R.sub.3).sub.3 ; and (R.sub.1).sub.x Si(OCOR.sub.2).sub.y and combinations thereof, wherein R.sub.1, R.sub.2 and R.sub.3 are independently H, alkyl, aryl, and x is an integer ranging in value from 1 to 2, and y is an integer ranging in value from 2 to about 3, and x and y are the same or different.
