  • Patent number: 8524833
    Abstract: A high-efficiency light diffusing polymeric film comprises a first polymer which is a light transmissible medium, and a second polymer which forms light scattering particles, wherein the polymers are immiscible and have a refractive index difference of about 0.001 to about 0.5, and the polymeric film comprises about 30 about to 70 parts by weight of the second polymer with respect to 100 parts by weight of the first polymer. A method for manufacturing a high-efficiency polymeric film is carried out such that a first polymer forms a continuous phase and a second polymer forms a dispersed phase through coating or extrusion.

  • Publication number: 20090294046
    Abstract: The invention concerns an anisotropic conductive film used for adhering IC, e.g., LCD displays, etc. The conductive film is characterized by comprising a thermosetting adhesive, super-paramagnetic metal oxide nano-particles, and conductive particles, the super-paramagnetic metal oxide nano-particles and the conductive particles being dispersed in a thermosetting composition. With such a configuration in the invention, it is advantageous that low temperature curing is implemented by means of high frequencies and positions of particles can be controlled by means of a magnetic field in adhering IC, e.g., LCD displays, so that high connection reliability is achieved for connection electrodes of fine pitches.

  • Publication number: 20080226884
    Abstract: The invention concerns an adhesive film for stacking chips which enables chips to be stacked in layers without using a separate spacer usually provided to keep a given distance between wires of an upper chip and a lower chip to have the same area. The adhesive film of the invention has an intermediate adhesive layer of thermoplastic phenoxy resin on both side of which a thermosetting adhesive layer of epoxy resin is placed, respectively, to make a three-layer structure, the thermoplastic phenoxy resin comprising UV curable small molecule compounds. The adhesive film of the invention is a multi-layered adhesive film produced by a method of comprising the steps of achieving compatibility on an interface between the thermosetting epoxy resin and thermoplastic phenoxy resin and then directly forming a phenoxy film of a high elastic modulus through UV curing in an adhesive film.
