Abstract
To provide a semiconductor device in which a plurality of spherical members are easily stacked at predetermined positions, with at least one of the spherical members being formed of a semiconductor material and having a semiconductor element or wiring formed on the surface of the spherical semiconductor material. One spherical member is placed in a depression formed by three spherical semiconductors that are substantially in contact. The spherical members are stacked in three dimensions so that four spherical members form a triangular pyramid to thereby form a semiconductor device . In the stacked spherical semiconductors , there may be provided a connecting spherical semiconductor E, which only performs the function of electrically connecting the spherical semiconductors , and a dummy spherical member F, which only performs the function of filling a gap between other spherical members.
