Abstract
The present invention relates to an adhesive film, a dicing die bonding film and a semiconductor device. More specifically, the adhesive film of the present invention is characterized by comprising a base film and an adhesive layer and having a yield strength of 20 to 50 gf and a slope of tensile elastic region of 30 to 80 gf/mm at a thickness of 5 to 50 μm. In the present adhesive film, the yield strength and the slope of tensile elastic region are controlled so that the incidence of burrs may be predicted and controlled depending on thickness of an adhesive layer. The dicing die bonding film, and the semiconductor device comprising the same have lower incidence of burrs and an excellent workability and reliability.
