Embodiment Construction
[0025] As mentioned in the background, the performance of the packaging structure formed by the existing flip-chip process is poor.
[0026] Figure 1 to Figure 2 is a schematic diagram of the structure of the flip-chip method.
[0027] refer to figure 1 , providing a semiconductor chip 100, a conductive connecting column 110 and a carrier plate 130, the conductive connecting column 110 has an opposite first surface and a second surface; the conductive connecting column 110 is fixed on the surface of the semiconductor chip 100, the first Facing the semiconductor chip 100; the solder ball 140 is fixedly arranged on the second surface of the conductive connection column 110; after that, the semiconductor chip 100, the conductive connection column 110 and the solder ball 140 are placed on the surface of the carrier board 130, and the solder ball 140 is connected to the surface of the carrier plate 130. The carrier board 130 is in surface contact.
[0028] refer to figure 2 A...
