  • Patent number: 9267059
    Abstract: After an adhesive sheet is pasted on a semiconductor wafer, an adhesive of the sheet increases tight attachment to the semiconductor wafer because wetting spreads over time. Due to this, at the time of peeling the adhesive sheet from the ground semiconductor wafer, the semiconductor wafer used to be damaged. This phenomenon is likely to occur for a thinner semiconductor wafer. The present invention resides in an adhesive sheet including a substrate and an adhesive layer disposed on the substrate. The substrate is formed of an ethylene/vinyl acetate copolymer having a vinyl acetate content of 10% by mass or less. The adhesive layer contains 100 parts by mass of a (meth)acrylate ester copolymer, 1 to 10 parts by mass of a cross-linker, 0.05 to 5 parts by mass of a silicone compound. The (meth)acrylate ester copolymer is formed of a copolymer produced by polymerizing a (meth)acrylate ester monomer and a functional-group-containing monomer.

  • Patent number: 9018777
    Abstract: An encapsulating composition for a light emitting element, a light emitting diode (LED) and a liquid crystal display device (LCD) are provided. A silicone-cured product included as a main ingredient and a conductivity-providing agent having excellent compatibility and capable of providing superior conductivity can be used to significantly reduce the surface resistivity of the silicone-cured product. Therefore, the encapsulating composition for a light emitting element, the LED and the LCD can be useful in solving the problems regarding attachment of a foreign substance such as dust due to static electricity, and degradation of transparency since the composition has low surface resistivity when used as a semiconductor encapsulation material for an LED, and also in providing a cured product having excellent properties such as light resistance, heat resistance, durability and optical transparency.
