摘要 | The present invention provides a dicing die bond film in which yielding and breaking of the dicing film are prevented and in which the die bond film can be suitably broken with a tensile force. In the dicing die bond film of the present invention, the tensile strength of the contact part in which the outer circumference of the push-up jig contacts the dicing film at 25° C. is 15 N or more and 80 N or less and the yield point elongation is 80% or more, the tensile strength of the wafer bonding part of the dicing film at 25° C. is 10 N or more and 70 N or less and the yield point elongation is 30% or more, [(the tensile strength of the contact part)−(the tensile strength of the wafer bonding part)] is 0 N or more and 60 N or less, and the breaking elongation rate of the die bond film at 25° C. is more than 40% and 500% or less. |
