Abstract:
The present invention relates to polymethylsilsesquioxane copolymers, and methods for preparing the copolymers and low-dielectric PMSSQ coating films. Polymethylsilsesquioxane copolymer of the present invention is synthesized by a copolymerization reaction using a methyltrialkokxysilane nullA: CH3Si(OR)3null and null,null-bistrialkokxysilane compound nullB: (RO)3SinullXnullYnullSi(OR)3, wherein X and Y are identical or different hydrocarbon groups and are linked to each other by carbonnull as a copolymerization monomer, and it contains SinullOH terminal group more than 10% in content, and has molecular weight ranging from 5,000 to 30,000. The coating film prepared from the low dielectric PMSSQ according to the present invention meets the two inevitable requirements for next generation semiconductor industry, i.e., mechanical strength (hardness 1.9 Gpa, Modulus 12 Gpa) and low dielectric property (

Abstract:
Disclosed are invisible logos, undetectable to the human eye, that may be temporarily viewed in response to stimuli. The invisible logo may be made by forming a hydrophilic coating and a hydrophobic coating on a substrate surface, so that a portion of the hydrophilic coating and a portion of the hydrophobic coating are exposed.
Abstract:
A security card is provided in which an ink region 6 bearing image or textural data is printed onto a substrate 4. A reflective portion 8 is also provided on the substrate 4. A plastics protective layer 7 is deposited over the ink 6 and reflective element 8. Portions 10 of the protective layer 7 are overworked in order to change their appearance. Those portions overlying the reflective element 8 exhibit enhanced visibility.
Abstract:
A thermal physical vapor deposition apparatus includes an elongated vapor distributor disposed in a chamber held at reduced pressure, and spaced from a structure which is to receive an organic layer in forming part of an OLED. One or more detachable organic material vapor sources are disposed outside of the chamber, and a vapor transport device including a valve sealingly connects each attached vapor source to the vapor distributor. During vapor deposition of the organic layer, the structure is moved with respect to the vapor distributor to provide an organic layer of improved uniformity on the structure.
Abstract:
This invention provides a composite device whereby surface reflection and interference colors can be inhibited, photocatalytic decomposition performance may be improved and hydrophilicity-acquiring rate may be improved. A mixture film (14) is deposited on the surface of a base (12). The mixture film (14) is a colorless and transparent mixture film with a high light transmittance made of a mixture of boron oxide and photocatalytic titanium oxide.
Abstract:
A heat treatable coated article including an infrared (IR) reflecting layer (e.g., of or including Ag), the coated article being able to attain a nullE* (glass side) no greater than about 3.5, more preferably no greater than 3.0, and even more preferably no greater than 2.6, following or due to heat treatment (e.g., thermal tempering). Accordingly, low-E (i.e., low emissivity) coated articles of certain embodiments of-this invention appear from the glass side thereof visually similar to the naked eye both before and after heat treatment. Good matchability characteristics (i.e., low nullE* values) combined with good durability can be achieved by controlling to what extent barrier layer(s) in contact with the IR reflecting layer are nitrided and to what thickness(es) they are sputtered. Optionally, certain embodiments of this invention relate to coated articles that also have high visible transmission and/or good durability. Coated articles herein may be used in the context of insulating glass (IG) window units, vehicle windows, or any other suitable applications. In certain embodiments of this invention, an exemplary layer stack includes: glass/Si3N4/NiCrNx/Ag/NiCrNx/Si3N4. Other materials may instead be used without departing from the scope and/or spirit of the instant invention which is a low-E matchable and/or durable product.

Abstract:
A method of manufacturing an organic EL display in which organic EL devices are prevented from being promoted in degradation by interfaces that occur between the hole transporting layer and the luminescent layer and between the luminescent layer and the electron transporting layer during the formation of the organic EL devices. The material of the luminescent layer is evaporated from a first evaporation source. At that time, the first evaporation source is moved from one end of a glass substrate to the other. Consequently, the luminescent layer is formed evenly on the glass substrate. After the formation of the luminescent layer is completed, the material of the electron transporting layer is evaporated from a second evaporation source. The second evaporation source is moved as if the first evaporation source is, whereby the electron transporting layer is formed evenly.
