Abstract

A stacked-chip device includes a first inductive chip having a first function, a second inductive chip having a second function different from the first function, which is stacked on the first inductive chip, and a third inductive chip having the second function, which is stacked on the second inductive chip. Each of the first, second and third inductive chips has transmitting inductors which transmit data and receiving inductors which receive data. The transmitting inductors and the receiving inductors are disposed in line symmetry to an axis of symmetry. The axes of symmetry of the first, second and third inductive chips are overlapped. Each of the second and third inductive chips is disposed in upside-down or back to front to the first inductive chip.
