Abstract
A semiconductor integrated circuit device has a semiconductor chip, interposer, and substrate. The semiconductor chip has a plurality of first pads arranged at first pitches on a surface. The interposer has a first surface and a second surface. On the first surface, a plurality of second pads are arranged at the first pitches. On said second surface, a plurality of third pads arranged at second pitches which are larger than the first pitches. The second pads and the first pads are connected to each other by joining the first surface of the interposer to the surface of the semiconductor chip so as to face each other. The substrate has a plurality of fourth pads arranged at the second pitches on a surface. The fourth pads and the third pads are connected to each other by joining the surface of the substrate to the second surface of the interposer so as to face each other.
