Abstract:
The present invention relates to processes for the structuring of surfaces of substrates in which a substrate is structured in a first step and, in a second step, coated by the sol-gel process for partial smoothing of the structuring, giving, in particular, a surface which scatters in a diffuse manner. The present invention likewise relates to substrates structured in this way and to the use thereof in optical applications
Abstract:
A method of making a polymer coating on a microstructured substrate. The method may be performed by vaporizing a liquid monomer or other pre-polymer composition and condensing the vaporized material onto a microstructured substrate, followed by curing. The resulting article may possess a coating that preserves the underlying microstructural feature profile. Such a profile-preserving polymer coating can be used to change or enhance the surface properties of the microstructured substrate while maintaining the function of the structure.
Abstract:
One embodiment of the present invention is a method for fabricating a dielectric film, comprising chemical vapor depositing a dielectric film, and curing the dielectric film, wherein the dielectric film comprises silicon and carbon, and the chemical vapor depositing utilizes a precursor comprising one or more organo-silicon compounds and one or more carbon-carbon bond containing hydrocarbon compounds.
Abstract:
Surface covering components that include a topcoat layer with different gloss levels in various regions on the top coat layer, and methods of manufacturing such surface covering components, are disclosed. The surface covering components include a coating layer that includes regions that have a relatively higher gloss, and regions with a relatively lower gloss. The differential gloss is provided by coating a substrate with a UV-curable coating composition, subjecting a first region of the surface coating to polymerization under a first set of conditions, and subjecting a second region of the surface coating to polymerization under a second set of conditions. The UV-curable coating compositions include UV-curable components and one or more flatting agents. The different polymerization conditions involve applying various photoinitiators, thermal initiators and/or cure altering agents to some regions of the coated substrate, and not applying these components to other regions of the substrate. The components are applied in the form of a pattern. Regions in contact with these components are cured at different rates in one step or in different steps, for example, sequential UV and EB irradiation or UV irradiation at different wavelengths and/or exposure times. The resulting surface coverings and surface covering substrates have differential gloss in register with the printed and/or sprayed patterns.
Abstract:
A method of forming a thin film on a substrate to fabricate a microelectronic device, a microelectronic device comprising a thin film deposited according to the method, and a system comprising the microelectronic device. The thin film may include on of a low k thin film, a thin film comprising photoresist, and a sacrificial polymer. The method comprises dispersing a precursor preparation into a spray of charged droplets through subjecting the liquid precursor preparation to electrostatic forces; directing the charged droplets to move toward the substrate; and allowing the charged droplets to generate a beam of gas-phase ions as the charged droplets move toward the substrate. The method further includes directing the gas-phase ions to impinge upon the substrate to deposit the thin film thereon to yield a deposited thin film on the substrate.

Abstract:
The invention relates to a process and to the corresponding apparatus for the production of strongly adherent coatings on an inorganic or organic substrate, wherein in a first step a) a low-temperature plasma, a corona discharge or a flame is caused to act on the inorganic or organic substrate, in a second step b) one or more photoinitiators or mixtures of photoinitiators with monomers, containing at least one ethylenically unsaturated group, or solutions, suspensions or emulsions of the afore-mentioned substances, are applied at normal pressure to the inorganic or organic substrate, in a third step c) using suitable methods those afore-mentioned substances are dried and/or irradiated with electromagnetic waves and, optionally, in a fourth step d) on the substrate so pretreated is deposited a metal, half-metal or metal oxide.
