Method of manufacturing an electronic parts packaging structure

In an electronic parts packaging structure of the present invention constructed by stacking a plurality of sheet-like units in a thickness direction, each of the units includes a first insulating layer, wirings formed on one surface of the first insulating layer, a semiconductor chip (electronic parts) connected to the wirings, a second insulating layer formed on an one surface side of the first insulating layer to cover the semiconductor chip, and connecting portions (terminals and contact vias) for connecting electrically the wirings and wirings of other unit, wherein arrangement of the first insulating layer, the semiconductor chip, the wirings, and the second insulating layer is symmetrical between units adjacent in a thickness direction.

Electronic parts packaging structure

In a semiconductor device, via holes are formed around a chip buried in a package, one end of a conductor filled in the via hole is covered with a pad portion exposed to the outside, and a wiring layer connected to the other end of the conductor is formed. The portion (pad portion) of the wiring layer which correspond to the conductor is exposed from a protective film, or an external connection terminal is bonded to the top of the pad portion. Electrode terminals of the chip are connected to the wiring layer, and the opposite surface of the chip is exposed to the outside.

Semiconductor device and method of manufacturing the same

In a semiconductor device, via holes are formed around a chip buried in a package, and conductor layers are respectively formed to be connected to one end and another end of the conductor filled in the individual via hole. Portions (pad portions) of the conductor layers which correspond to the conductors are exposed from protective films, or external connection terminals are bonded to the pad portions. The chip is mounted with flip-chip technology so that at least some of electrode terminals thereof are electrically connected to the conductor layers.
