A semiconductor device typified by a wireless tag, which has improved mechanical strength, can be formed by a more simple process at a low cost and prevent radio waves from being shielded, and a manufacturing method of the semiconductor device. According to the invention, a wireless tag includes a thin film integrated circuit formed of an isolated TFT having a thin film semiconductor film. The wireless tag may be attached directly to an object, or attached to a flexible support such as plastic and paper before being attached to an object. The wireless tag of the invention may include an antenna as well as the thin film integrated circuit. The antenna allows to communicate signals between a reader/writer and the thin film integrated circuit, and to supply a power source voltage from the reader/writer to the thin film integrated circuit.
