Patent ID: 7141873

Claim:
A semiconductor device comprising: a plurality of first semiconductor devices each of which includes a first semiconductor chip; a second semiconductor device which includes a second semiconductor chip, the first semiconductor devices being disposed on the second semiconductor device so as not to overlap each other; and two or more groups of external terminals which are disposed between the first semiconductor devices and the second semiconductor device and electrically connect the first semiconductor devices to the second semiconductor device, each of the groups being disposed in a region of one of the first semiconductor devices, wherein at least one of the groups of the external terminals include at least one first external terminal and two or more second external terminals; wherein the first external terminal is formed of a soldering material; wherein each of the second external terminals includes a soldering material and a plurality of particles formed of a resin and dispersed in the soldering material; wherein the shape of a region in which each of the groups is disposed is a rectangle; and wherein the second external terminals are disposed in a region along short sides of the rectangle.
