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.
