Classification: CPC H | IPC H

Claim 0:
1. A semiconductor device comprising:
a first interposer having a first main surface;
a second interposer disposed on the first main surface, the second interposer having a second main surface on a side opposite to the first interposer, and formed of a material different from the first interposer;
a first semiconductor chip having a first front surface facing the second main surface, the first semiconductor chip mounted on the second main surface using a plurality of bump electrodes, the first semiconductor chip further including a volatile memory circuit; and
a second semiconductor chip mounted on a plurality of electrode patterns disposed on the first main surface or the second main surface through a plurality of bonding wires,
wherein the second interposer overlaps the first semiconductor chip in a direction perpendicular to the first main surface,
wherein the first interposer has an opening in the first main surface, and the second interposer is disposed within the opening.
