<P>PROBLEM TO BE SOLVED: To provide a semiconductor device for exchanging data through wireless communication, in which the sensitivity of an antenna is increased without enlarging the device and a chip is protected from a noise. <P>SOLUTION: A semiconductor device comprises a coil-shaped antenna and a semiconductor integrated circuit electrically connected to the coil-shaped antenna. The semiconductor integrated circuit is disposed so as to overlap with the coil-shaped antenna. By devising the arrangement of the coil-shaped antenna and the semiconductor integrated circuit in the semiconductor device in this manner, the sensitivity of the antenna can be improved without enlarging the device and enough power to operate the semiconductor integrated circuit can be obtained. <P>COPYRIGHT: (C)2012,JPO&INPIT |
