Embodiment approach 2

[0247] Figure 11 It is a cross-sectional view showing a semiconductor device according to Embodiment 2 of the present invention. Figure 11 Embodiment 2 of the present invention shown has a structure similar to Embodiment 1 of the present invention shown in FIG. package) structure) is different from Embodiment 1.

[0248] exist Figure 11 2 shows a structure in which BGA-type packages are stacked in two stages, however, it is not limited to BGA-type packages, and may be a structure in which TSOP-type packages having wiring on external terminals are stacked. also, Figure 11 2 shows a method in which two sets of packages are stacked in two stages, but three or more sets may be used as long as the area limit permits. In addition, as long as the height limit allows, the package can also be stacked more than 3 levels, and it can also include non-stacked packages. Furthermore, even a single package may include a multi-chip package including a plurality of memory dies inside. ...

Abstract

Provided is a semiconductor device which includes a flexible circuit board whereupon a first external electrode is arranged on a first surface and second and third external electrodes are arranged on a second surface; a plurality of memory devices and passive components; a supporting body having a groove on one surface; and an arithmetic processor device. The memory devices and the passive components are connected to the first external electrode, the one surface of the supporting body is bonded on the first surface of the flexible circuit board so that a groove stores the memory devices and the passive components. The flexible circuit board is bent along the periphery of the supporting body, and wraps the side surfaces and the other surface of the supporting body. On the flexible circuit board, the second external electrode is arranged on the second surface which faces the first external electrode, and the third external electrode is arranged on the second surface which is bent to the other surface of the supporting body. The arithmetic processor device is connected to the second external electrode, and a bump is formed on the third external electrode.

Description
