Abstract:
1. A semiconductor device comprising: a semiconductor element having a plurality of electrodes; an interposer having electrodes arranged on a top face thereof in four directions and external electrodes arranged on a bottom face thereof with the semiconductor element mounted on the top face thereof; an adhesive material fixing the semiconductor element to the top face of the interposer; metal nanowires electrically connecting between the plurality of electrodes of the semiconductor element and the electrodes, arranged in four directions, of the interposer; an insulating material sealing a region containing the semiconductor element and the metal nanowires; and metal balls mounted on the external electrodes of the interposer, wherein at least a pair of patterns, different in shape from the electrodes arranged in four directions, are designed on diagonal corners of a region surrounded by the electrodes arranged on the interposer in four directions, and the at least a pair of patterns is within a region surrounded in four directions by the electrodes.
