STACKED ELECTRONIC DEVICE HAVING INDUCTIVE COUPLING COMMUNICATION UNIT BETWEEN STACKED CHIPS

摘要

PURPOSE: An electronic device including an inductive coupling communication unit is provided to stably transmit and receive a signal with low power by reducing an eddy current. CONSTITUTION: A first silicon chip and a second silicon chip are successively laminated. A first inductor(112) is arranged on the first silicon chip. A second inductor(122) is arranged on the second silicon chip to correspond to the first inductor and is inductively coupled with the first inductor. A penetration hole(130) is formed on the second silicon chip and includes an inductive coupling communication unit to correspond to the first inductor. The penetration hole is formed in the second inductor. An insulator fills the penetration hole.
