Abstract:
1. A method of dicing using a dicing die bonding film comprising a dicing film, of which an elongation is from 100% to 2,000%, the dicing film comprising a base film and a pressure sensitive adhesive layer formed on said base film; and a single layer of a die bonding film, of which a tensile modulus is 10 to 2,000 MPa at 25° C., the single layer being formed on said dicing film, the method comprising: a first step of adhering a wafer in direct contact with the die bonding film; a second step of carrying out dicing to a depth that the die bonding film is not completely cut; and a third step of expanding the dicing die bonding film to completely separate the die bonding film.
