PROBLEM TO BE SOLVED: To peel not only a peeled layer with small area, but also a peeled layer with large area over the entire surface in good yield by providing a peeling method which gives no damage to the peeled layers, to provide a semiconductor device which is made lightweight by sticking the peeled layers on various base material, and its manufacturing method, and to provide a semiconductor device which is made lightweight by sticking various elements (a thin-film diode, and a photoelectric converting element and silicon resistance element composed of PIN junctions of silicon) represented by a TFT, specially, on flexible film, and its manufacturing method. SOLUTION: A metal layer or nitride layer 11 is provided on a substrate, an oxide layer 12 is provided in contact with the metal layer or nitride layer 11. Even after lamination film formation or a heat treatment of≥500°C is carried out, fine separation in the oxide layer 12 or on its interface can easily be carried out by a physical means.
