Abstract:
1. A semiconductor device comprising: a first semiconductor chip comprising a transceiver circuit formed on a first surface, a first coupling conductive pattern formed on a second surface opposite the first surface, and a through electrode connecting the transceiver circuit and the first coupling conductive pattern; and a transceiver located on the first semiconductor chip and comprising a second coupling conductive pattern configured to wirelessly communicate data with the first coupling conductive pattern, wherein the second coupling conductive pattern is disposed to face the first coupling conductive pattern, wherein the first coupling conductive pattern is a first inductor, and the second coupling conductive pattern is a second inductor, wherein each of the first and second inductors comprises a field portion and a lead portion which branches from the field portion and is connected to the through electrode, wherein the field portion is loop shaped, wherein each of the first and second inductors further comprise a first connection portion interposed between the lead portion and the field portion and formed at a different level from the lead portion and the field portion, and electrically connecting the lead portion and the field portion.
