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. Structures can be produced having interconnected macroscopic pores and high refractive index contrasts, which can be used, for example, as photonic band gaps.

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.

Patterned structures of high refractive index materials

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.

Semiconductor device having a low dielectric constant dielectric material and process for its manufacture

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.

Method and apparatus for aligning a photo-tunable microlens

A process for device fabrication and resist materials that are used in the process are disclosed. The resist material contains a polymer in combination with a dissolution inhibitor and a photoacid generator (PAG). The dissolution inhibitor is the condensation reaction product of a saturated polycyclic hydrocarbon compound with at least one hydroxy (OH) substituent and a difunctional saturated linear, branched, or cyclic hydrocarbon compound wherein the functional groups are either carboxylic acid or carboxylic acid chloride groups. The condensation product has at least two polycylic moieties. The polymer optionally has acid labile groups pendant thereto which significantly decrease the solubility of the polymer in a solution of aqueous base. A film of the resist material is formed on a substrate and exposed to delineating radiation. The radiation induces a chemical change in the resist material rendering the exposed resist material substantially more soluble in aqueous base solution than the unexposed portion of the resist material. The image introduced into the resist material is developed using conventional techniques, and the resulting pattern is then transferred into the underlying substrate.

Energy-sensitive resist material and a process for device fabrication

The present invention is directed to a process for device fabrication and resist materials that are used in the process. The resist material contains a polymer that is the polymerization product of a monomer that contains alicyclic moieties and at least one other monomer. The polymer is formed by free radical polymerization, and the resulting polymer either has alicyclic moieties incorporated into the polymer backbone or pendant to the polymer backbone via saturated hydrocarbon linkages. Other monomers are selected for polymerization with the alicyclic moiety-containing monomer on the basis of the ability of the monomer to copolymerize by free radical polymerization. Although the polymers are contemplated as useful in resist materials that are sensitive to radiation in the ultraviolet, and x-ray wavelengths as well as sensitive to electron beam radiation, the polymers are particularly advantageous for use in process in which the exposing radiation is 193 nm, because the amount of ethylenic unsaturation in these resist materials is low.

A lithographic process for fabricating a device is disclosed. An area of radiation sensitive material is formed on a substrate. The radiation sensitive material contains a polymeric component The polymeric component is the copolymerization product of a maleimide monomer and at least two other monomers. Acid labile groups are pendant to one of the monomers with which the maleimide monomer is copolymerized. The acid labile groups are pendant to less than 50 mole percent of the monomers that make up the copolymer. The acid labile groups are not pendant to the maleimide monomer. The radiation sensitive material is patternwise exposed to radiation after it is formed on the substrate. The patternwise exposure transfers an image into the radiation sensitive material. The image is developed into a pattern in the radiation sensitive material. The pattern is then transferred into the substrate.
