Abstract: a method for thermo-compression bonding (tcb) a bridge die having a tsv to a redistribution layer is disclosed. in this method, a terminal electrode and an upper end of the tsv on the bridge die are covered with a thermosetting resin film (e.g. daf) to form a resin layer which is then cured. a metal collet c that sucks the bridge die is heated, and the heat is transferred to the entire surface of the resin layer while applying pressure, thereby heat-bonding a lower end of the tsv to the wiring electrode of the redistribution layer. according to this method, the amount of heat transferred to a bonded portion between the lower end and the wiring electrode increases the pressure during heat-bonding is applied to the entire surface of the resin layer thermo-compression is performed reliably.
