Die bond film, dicing die bond film, and semiconductor device

摘要

The present invention provides a die bond film for adhering, onto a semiconductor element that is electrically connected to an adherend with a bonding wire, another semiconductor element and that enables loading of the other semiconductor element and improvement in the manufacturing yield of a semiconductor device by preventing deformation and cutting of the bonding wire, and a dicing die bond film. The die bond film of the present invention is a die bond film for adhering, onto a semiconductor element that is electrically connected to an adherend with a bonding wire, another semiconductor element, in which at least a first adhesive layer that enables a portion of the bonding wire to pass through inside thereof by burying the portion upon press bonding and a second adhesive layer that prevents the other semiconductor element from contacting with the bonding wire are laminated.
