Publication number: 20070212875Abstract: An object of the present invention is to prevent a thin film integrate circuit from peeling off during the process of transferring to a base material. By a manufacturing method of the present invention, a separation layer is formed selectively on a surface of a substrate; thus, a first region where the separation layer is provided and a second region where the separation layer is not provided are formed. A thin film integrated circuit is formed over the separation layer. Then, an opening portion for exposing the separation layer is formed, en etching agent is introduced into the opening portion to remove the separation layer. Thus, a space is generated in the region provided with the separation layer, whereas a space is not generated in the region without the separation layer. Therefore, the thin film integrated circuit can be prevented from peeling off even after the separation layer is removed, by providing the region where the space is not generated after that.Type: ApplicationFiled: June 15, 2005Publication date: September 13, 2007Applicant: SEMICONDUCTOR ENERGY LABORATORY CO., LTD.Inventors: Takuya Tsurume, Koji Dairiki
