摘要： It is an object of the present invention to provide a method for manufacturing a semiconductor device, capable of keeping a peeling layer from being peeled from a substrate in the phase before the completion of a semiconductor element and peeling a semiconductor element rapidly. It is considered that a peeling layer tends to be peeled from a substrate because the stress is applied to a peeling layer due to the difference in thermal expansion coefficient between a substrate and a peeling layer, or because the volume of a peeling layer is reduced and thus the stress is applied thereto by crystallization of the peeling layer due to heat treatment. Therefore, according to one feature of the invention, the adhesion of a substrate and a peeling layer is enhanced by forming an insulating film (buffer film) for relieving the stress on the peeling layer between the substrate and the peeling layer before forming the peeling layer over the substrate.

摘要： It is an object of the present invention to provide a method of separating a thin film transistor, and circuit or a semiconductor device including the thin film transistor from a substrate by a method different from that disclosed in the patent document 1 and transposing the thin film transistor, and the circuit or the semiconductor device to a substrate having flexibility. According to the present invention, a large opening or a plurality of openings is formed at an insulating film, a conductive film connected to a thin film transistor is formed at the opening, and a peeling layer is removed, then, a layer having the thin film transistor is transposed to a substrate provided with a conductive film or the like. A thin film transistor according to the present invention has a semiconductor film which is crystallized by laser irradiation and prevents a peeling layer from exposing at laser irradiation not to be irradiated with laser light.

摘要： The present invention is characterized in that by laser beam being slantly incident to the convex lens, an aberration such as astigmatism or the like is occurred, and the shape of the laser beam is made linear on the irradiation surface or in its neighborhood. Since the present invention has a very simple configuration, the optical adjustment is easier, and the device becomes compact in size. Furthermore, since the beam is slantly incident with respect to the irradiated body, the return beam can be prevented.
