Semiconductor package and its manufacturing method
Abstract:
Provided is a bonding method to construct a bonding with high thermal reliability between electrodes formed on both chip surfaces of a semiconductor device and wiring. The bonding method includes: bonding a semiconductor chip over a first substrate with a bonding film interposed therebetween; forming a first insulating film over the semiconductor chip; forming a first via in the first insulating film; forming a first wiring over the first insulating film so as to be electrically connected to the semiconductor chip through the first via; forming a second via in the bonding film; and forming a second wiring under the semiconductor chip so as to be electrically connected to the semiconductor chip through the second via.
