It has been difficult to manufacture a semiconductor device equipped with a microstructure having a space, an electric circuit for controlling the microstructure, and the like over one substrate. In a semiconductor device, a microstructure and an electric circuit for controlling the microstructure can be provided over one substrate by manufacturing the microstructure in such a way that a structural layer having polycrystalline silicon obtained by laser crystallization or thermal crystallization using a metal element is formed and processed at low temperature. As the electric circuit, a wireless communication circuit for carrying out wireless communication with an antenna is given.
