    摘要: The invention realizes excellent electrical and mechanical connection between electrodes in a packaging structure where a plurality of semiconductor chips having electrodes are connected with each other through the low-melting metallic members. Bump electrodes are formed on a front surface of a first semiconductor chip. Penetrating holes are formed in a second semiconductor chip, and a penetrating electrode having a gap in a center is formed in each of the penetrating holes. Low-melting metallic members are interposed between connecting surfaces of the bump electrodes and the penetrating electrodes, and a part of each of the low-melting metallic members flows in each of the gaps of the penetrating electrodes when dissolved. This prevents short-circuiting between the bump electrodes which is caused by oversupplying the low-melting metallic members between the adjacent bump electrodes.

    摘要: This invention offers a manufacturing method to reduce a manufacturing cost of a semiconductor device having a through-hole electrode by simplifying a manufacturing process and to enhance yield of the semiconductor device. A first insulation film is formed on a top surface of a semiconductor substrate. A part of the first insulation film is etched to form an opening in which a part of the semiconductor substrate is exposed. Then a pad electrode is formed in the opening and on the first insulation film. A second insulation film is formed on a back surface of the semiconductor substrate. Then a via hole having an aperture larger than the opening is formed. And a third insulation film is formed in the via hole and on the second insulation film. The third insulation film on a bottom of the via hole is etched to expose the pad electrode. After that, a through-hole electrode and a wiring layer are formed in the via hole. Finally, the semiconductor substrate is cut and separated into a plurality of semiconductor dice.
