SEMICONDUCTOR DEVICE

PROBLEM TO BE SOLVED: To provide a semiconductor device capable of being compatible with both the cases of connection to an external antenna and connection to an on-chip antenna. SOLUTION: The semiconductor device is provided with an antenna connection electrodes 1a, 2 provided at an outer edge of a semiconductor chip 10, an on-chip antenna connection electrode 1b provided inwardly from the antenna connection electrodes 1a, 2, and an internal circuit 4b formed to the semiconductor chip. The antenna connection electrodes 1a, 2 are connected to the internal circuit 4b by internal wires 4a, 4c. Further, the on-chip antenna connection electrode 1b is connected to the internal circuit 4b and the antenna connection electrode 2 by the internal wires 4a, 4c. An on-chip antenna 32 is connected to the antenna connection electrode 2 and the on-chip antenna connection electrode 1b. An external antenna 200 is connected to the antenna connection electrodes 1a, 2. COPYRIGHT: (C)2004,JPO&NCIPI
