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.
