Claim:
1. A semiconductor device comprising: a first circuit board having a first chip and a second chip mounted on a first base, with the second chip having a greater height from the first base than that of the first chip; a second circuit board having a third chip and a fourth chip mounted on a second base, the fourth chip having a greater height from the second base than that of the third chip, with the second circuit board disposed overlapping with the first circuit board such that the second base faces the first chip, and the second base not contacting the second chip; and an interposer that is disposed between the first base and the second base, and that electrically connects the first base and the second base, the height of the interposer from the first base is substantially the same as the height of the first chip from the first base.
