Patent ID: 8728868

Claim:
A method for manufacturing a semiconductor device, the method comprising the steps of: forming a first film and a second film on a substrate; forming a layer comprising a first circuit on the first film and a second circuit on the second film; cutting the substrate and the layer such that the substrate is divided into a first piece of the substrate and a second piece of the substrate and the layer is divided into a first piece of the layer comprising the first circuit and a second piece of the layer comprising the second circuit; attaching a supporting material on a first surface of the first piece of the layer; removing an end portion of the first piece of the substrate; peeling the first piece of the substrate from the first film on a second surface of the first piece of the layer; attaching a base material on the second surface of the first piece of the layer; irradiating the supporting material with ultraviolet; and peeling the supporting material from the first surface of the first piece of the layer.
