  • Publication number: 20220026603
    Abstract: Embodiments of the present disclosure relate to optical device films and methods of forming optical device films. Specifically, embodiments described herein provide for an optical device film having a constant oxygen-concentration, a first concentration profile of the first material, and a second concentration profile of the second material. The first material, described and referenced to herein, has a first refractive index about 2.0 or greater and the second material has a second refractive index less than 2.0.

  • Publication number: 20220025518
    Abstract: Embodiments of the present disclosure generally relate to methods and materials for optical device fabrication. More specifically, embodiments described herein provide for optical film deposition methods and materials to expand the process window for amorphous optical film deposition via incorporation of dopant atoms by suppressing the crystal growth of optical materials during deposition. By enabling amorphous films to be deposited at higher temperatures, significant cost savings and increased throughput are possible.

  • Publication number: 20210325777
    Abstract: Embodiments of the present disclosure generally relate to optically densified nanoimprint films and processes for making these optically densified nanoimprint films, as well as optical devices containing the optically densified nanoimprint films. In one or more embodiments, a method of forming a nanoimprint film includes positioning a substrate containing a porous nanoimprint film within a processing chamber, where the porous nanoimprint film contains nanoparticles and voids between the nanoparticles, and the porous nanoimprint film has a refractive index of less than 2. The method also includes depositing a metal oxide on the porous nanoimprint film and within at least a portion of the voids to produce an optically densified nanoimprint film during an atomic layer deposition (ALD) process.

  • Publication number: 20210325778
    Abstract: Embodiments of the present disclosure generally relate to densified nanoimprint films and processes for making these densified nanoimprint films, as well as optical devices containing the densified nanoimprint films. In one or more embodiments, a densified nanoimprint film contains a base nanoimprint film and a metal oxide disposed on the base nanoimprint film and in between the nanoparticles. The base nanoimprint film contains nanoparticles, where the nanoparticles contain titanium oxide, zirconium oxide, niobium oxide, tantalum oxide, hafnium oxide, chromium oxide, indium tin oxide, silicon nitride, or any combination thereof. The metal oxide contains aluminum oxide, titanium oxide, zirconium oxide, niobium oxide, tantalum oxide, indium oxide, indium tin oxide, hafnium oxide, chromium oxide, scandium oxide, tin oxide, zinc oxide, yttrium oxide, praseodymium oxide, magnesium oxide, silicon oxide, silicon nitride, silicon oxynitride, or any combination thereof.
