PROBLEM TO BE SOLVED: To provide a semiconductor chip of integral rewiring layer which is hard to cause malfunction due to noise and deterioration of transmission characteristic, and also to provide a semiconductor device with good transmission characteristic. SOLUTION: A rewiring layer 3 is formed on a circuit forming plane 1a via an insulating layer 2, and an antenna coil 4 is formed by rewiring layer 3. Antenna coil 4 is formed near an analog circuit 21, not in or to circuit 21 itself, which is formed on circuit forming plane 1a. Analog circuit 21 can be an integration of all analog circuits to be formed on a semiconductor chip 1A, or one of a power circuit, an operational amplifier, a comparative amplifier, an RF receiver, an RF sender and an RF synthesizer, and an analog circuit that is easy to be affected by noise as a voltage rising circuit or an amplifying circuit constituting a part of a memory part, or it can be a coil constituting a part of the analog circuits to be formed in semiconductor chip 1A. |
