Abstract:
1. A dicing die bond film comprising a die bond layer provided on a dicing layer, wherein: the dicing layer has: a ring bonding part to which a dicing ring is bonded, the ring bonding part located at an outer circumference of the dicing layer, a tensile strength of the contact part of the dicing layer at 25° C. is 15 N or more and 80 N or less, and a yield point elongation of the contact part is 80% or more, a tensile strength of the wafer bonding part of the dicing layer at 25° C. is 10 N or more and 70 N or less, and a yield point elongation of the wafer bonding part 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 a breaking elongation rate of the die bond layer at 25° C. is more than 40% and 500% or less.
