A task of the present invention is to provide a method for producing a formed article comprised of a fiber without using a frame having a fixed form. A portion of the well forming layer is removed effective to form at least one well within the well forming layer. The essence of the present invention is using charge-discharge through the sensing-controlling terminal and the IO control terminal for sensing whether a conductor contacts the sensing electrode. In some embodiments, the cloud password may be periodically flushed so that subsequent requests may be passed to the cloud authentication mechanism. Therefore, it is possible to uniformly thin the film thickness of each of the semiconductor thin films.
