  • Patent number: 7168266
    Abstract: Techniques for producing a glass structure having interconnected macroscopic pores, employing steps of filling polymerizable glass precursors into pores in a polymeric structure having interconnected macroscopic pores; polymerizing the precursors; and decomposing the polymers to produce a glass oxide structure having interconnected macroscopic pores. Further techniques employ steps of exposing portions of a photosensitive medium including glass precursors to an optical interference pattern; polymerizing or photodeprotecting the exposed portions and removing unpolymerized or deprotected portions; and decomposing the polymerized or deprotected portions to produce a glass structure having interconnected macroscopic pores. Techniques for filling pores of such glass structure with a material having a high refractive index, and for then removing the glass structure.

  • Publication number: 20060099536
    Abstract: A process for forming a polymer template includes exposing a photoresist having polymer molecules to a light pattern and baking the photoresist to chemically react polymer molecules in portions of the photoresist that were exposed to light of the light pattern. The reacted polymer molecules have a different solubility in a solvent than chemically unreacted polymer molecules. The process also includes washing the baked photoresist with the solvent to produce a porous structure by selectively solvating one of the reacted polymer molecules and the unreacted polymer molecules. The porous structure can be used as template for forming porous structures of high refractive index materials.

  • Patent number: 6852648
    Abstract: A process for fabricating an integrated semiconductor device with a low dielectric constant material and an integrated semiconductor device with the low dielectric constant material interposed between two conductors is disclosed. The low dielectric constant material has a dielectric constant of less than about 2.8. The low dielectric constant material is a porous glass material with an average pore size of less than about 10 nm. The low dielectric constant material is formed on a semiconductor substrate with circuit lines thereover by combining an uncured and unmodified glass resin with an amphiphilic block copolymer. The amphiphilic block copolymer is miscible in the uncured glass resin. The mixture is applied onto the semiconductor substrate and the glass resin is cured. The glass resin is further processed to decompose or otherwise remove residual block copolymer from the cured glass resin.

  • Patent number: 6665127
    Abstract: A tunable microlens uses a layer of photo-conducting material which results in a voltage differential between at least one of a plurality of electrodes and a droplet of conducting liquid when a light beam is incident upon the photo-conducting material. Such droplet, which forms the optics of the microlens, moves toward an electrode with higher voltage relative to other electrodes in the microlens. Thus, for example, when the light beam is misaligned with the microlens, the voltage differential causes the droplet, and hence the microlens, to realign itself with the beam.
