Abstract: Provided are an epoxy composition, an adhesive film, a dicing die bonding film and a semiconductor device using the same. Specifically, the epoxy composition and a use thereof are provided, wherein the epoxy composition has a gel content of 5˜20%, measured under certain conditions. The epoxy composition according to the present invention, as an adhesive agent, shows excellent elastic properties, when prepared to have a low glass transition temperature, exhibiting good adhesion at high temperature and having minimal occurrence of burrs during processing. According to the present invention, it is therefore possible to prevent defects owing to die cut shift, during a wire bonding or molding process at high temperature, and obtain a highly reliable semiconductor device owing to the excellent adhesiveness and workability of the adhesive agent.

Abstract: The present invention relates to a super-absorbent polymer having excellent properties, both centrifugal retention capacity (CRC) and absorption under pressure (AUP) having been improved by introducing a surface crosslinked layer crosslinked by surface-modified inorganic particles, and to a method for preparing the same. The super-absorbent polymer comprises: a base resin powder containing a crosslinked polymer of water-soluble ethylene-based unsaturated monomers having an at least partially neutralized acidic group; and a surface crosslinked layer formed on the base resin powder, wherein inorganic particles may be chemically bound to the crosslinked polymer contained in the surface crosslinked layer, via an oxygen-containing bond or a nitrogen-containing bond.
