Abstract:
1. An electronic parts packaging structure constructed by stacking a plurality of sheet-like units in a thickness direction, each of the units includes a first insulating layer, a wiring formed on one surface of the first insulating layer, an electronic parts connected to the wiring, a second insulating layer formed on one surface side of the first insulating layer to bury a whole of the electronic parts, and a connecting portion for electrically connecting the wiring and a wiring of another unit, wherein arrangement of the first insulating layer, the electronic parts, the wiring, and the second insulating layer is symmetrical between units adjacent in a thickness direction, and the connecting portion is constructed by a terminal formed to pass through the first insulating layer and bonded to one surface of the wiring, and a contact via formed to pass through the second insulating layer and bonded to another surface of wiring, the terminal protrudes from a surface of the first insulating film, a top portion of the contact via protrudes from a surface of the second insulating film, the terminals of neighboring units are electrically connected to each other or the conductive vias of neighboring units are electrically connected to each other.
