Patent application numberDescriptionPublished
20090311526Adhesive composition, film adhesive, and heat treatment method - An adhesive composition of the present invention contains, as a main composition, a polymer obtained by copolymerizing a monomer composition containing a monomer having a maleimide group, and further contains a thermal polymerization inhibitor. As a result, it is possible to provide an adhesive composition that allows forming an adhesive layer that is excellently dissolved after the adhesive layer has been subjected to a high-temperature process.12-17-2009
20100010182Adhesive composition, film adhesive, and method for producing the adhesive composition - An adhesive composition is disclosed which includes a polymer prepared by copolymerizing a monomer containing a polymerizable group, the polymer including a low-molecular-weight component having a molecular weight equivalent to 1% or less of the weight-average molecular weight of the polymer, the low-molecular-weight component is contained in a range of not less than 0 weight % to less than 0.3 weight % of the total weight of the polymer. This allows provision of an adhesive composition having great adhesive strength in a high-temperature environment, especially at temperatures from 140° C. to 200° C., as well as high heat resistance and favorable crack resistance.01-14-2010
20100068453METHOD FOR PRODUCING PROCESSED GLASS SUBSTRATE - A processed substrate of the present invention includes a translucent substrate having a plurality of through-holes, in each of which there is a gap from 0 to 5 μm between (a) a straight line which passes through a central point of an opening plane of the each of the plurality of through-holes and which is perpendicular to the opening plane and (b) a straight line which passes through a central point of the other opening plane of the each of the plurality of through-holes and which is perpendicular to the other opening plane, thereby making it possible to provide (i) a processed substrate having through-holes in each of which central axes are aligned, which can be easily produced with high productivity, and (ii) a production method thereof. Further, a production method of the present invention of a processed glass substrate includes: (a) forming photosensitive resin layers on surfaces of a glass substrate; (b) forming a through-hole in the glass substrate; and (c) immersing the glass substrate in acid, with the photosensitive resin layers remaining on the both surfaces. Accordingly, it is unnecessary to perform smoothing the surfaces of the glass substrate after the step (c), thereby successfully producing a processed glass substrate having a through-hole with high productivity.03-18-2010
20100086799Removal method, adhesive agent for substrate, and laminate including substrate - The removal method of the present invention includes: providing a support plate and a substrate being combined to each other via a first adhesive layer and a second adhesive layer, the second adhesive layer being an adhesive layer which is dissolvable in a solvent quicker than the first adhesive layer or an adhesive layer which is dissolvable in a solvent different from a solvent to which the first adhesive layer is dissolvable, and the second adhesive layer being between the support plate and the first adhesive layer; and removing the support plate from the substrate by dissolving the second adhesive layer. Further, the removal method of the present invention includes, after the step of removing, dissolving the first adhesive layer. This removes the support plate from the wafer in a quick and easy way.04-08-2010
