SUMMARY OF THE INVENTION An object of the present invention is to provide an ID chip capable of increasing the gain of an antenna and increasing the mechanical strength of an integrated circuit without suppressing the circuit scale. The semiconductor device represented by the ID chip of the present invention includes an integrated circuit using a semiconductor element formed of a thin film semiconductor film, and an antenna connected to the integrated circuit. The antenna and the integrated circuit are formed on the same substrate, and the conductor or conductive film included in the antenna is formed in two layers so as to sandwich the substrate on which the integrated circuit is formed.n n n n ID chip, integrated circuit, antenna, thin film semiconductor film |
