ABSTRACT:
It is an object of the present invention to provide an ID chip in which gain of an antenna is increased and the mechanical strength of an integrated circuit can be enhanced without suppressing a circuit scale. A semiconductor device typified by an ID chip of the present invention includes an integrated circuit using a semiconductor element formed from a thin semiconductor film and an antenna connected to the integrated circuit. The antenna and the integrated circuit are formed on a substrate, and a conducting wire or a conductive film included in the antenna is divided into two layers and formed so as to sandwich the substrate provided with the integrated circuit.
