Claim 10:
11. A method of forming a nanoimprint film, comprising:
positioning a substrate comprising a porous nanoimprint film within a processing chamber, wherein the porous nanoimprint film comprises nanoparticles and voids between the nanoparticles, and wherein the nanoparticles comprise zirconium oxide, niobium oxide, tantalum oxide, hafnium oxide, chromium oxide, silicon nitride, or any combination thereof; and
depositing a metal oxide on the porous nanoimprint film and within at least a portion of the voids to produce an densified nanoimprint film during an atomic layer deposition (ALD) process, wherein the metal oxide comprises niobium oxide, chromium oxide, scandium oxide, yttrium oxide, praseodymium oxide, magnesium oxide, silicon nitride, silicon oxynitride, or any combination thereof, and wherein:
the nanoparticles and the metal oxide contain different materials; and
the refractive index of the densified nanoimprint film is about 2% to about 30% greater than the refractive index of the base nanoim print film.
