    • The present invention is a separation method for easy separation of an allover release layer with a large area. Further, the present invention is the separating method that is not subjected to restrictions in the use of substrates, such as a kind of substrate, during forming a release layer. A separation method comprising the steps of forming a metal film, a first oxide, and a semiconductor film containing hydrogen in this order; and bonding a support to a release layer containing the first oxide and the semiconductor film and separating the release layer bonded to the support from a substrate provided with the metal layer by a physical means. Through the separation method, heat treatment is carried out to diffuse hydrogen contained in the semiconductor film, a third oxide is formed by reducing a second oxide formed at a surface boundary between the metal film and the first oxide film, and a film containing the second oxide and the third oxide, a surface boundary between the film containing the second oxide and the third oxide, and the metal film, or a surface boundary between the film containing the second oxide and the third oxide, and the first oxide is split.

    • (Object) It is an object of the present invention to provide a peeling method that causes no damage to a layer to be peeled and to allow not only a layer to be peeled with a small surface area but also a layer to be peeled with a large surface area to be peeled entirely. Further, it is also an object of the present invention to bond a layer to be peeled to various base materials to provide a lighter semiconductor device and a manufacturing method thereof. Particularly, it is an object to bond various elements typified by a TFT, (a thin film diode, a photoelectric conversion element comprising a PIN junction of silicon, or a silicon resistance element) to a flexible film to provide a lighter semiconductor device and a manufacturing method thereof. (Solving Means) When a metal layer 11 is provided over a substrate, an oxide layer 12 is provided in contact with the metal layer 11, a layer to be peeled 13 is formed, and the metal layer 11 is irradiated with a laser beam to perform oxidization and form a metal oxide layer 16, a clear separation is possible with a physical means within the metal oxide layer 12 or at an interface between the metal oxide layer 16 and the oxide layer 12.
    • (对象)本发明的目的是提供一种不会对被剥离层造成损害的剥离方法,并且不仅允许以小的表面积剥离层,而且还可以使用剥离层 大的表面积要完全剥离。 此外,本发明的另一个目的是将要剥离的层粘合到各种基材上以提供更轻的半导体器件及其制造方法。 特别地,目的是将由TFT表示的各种元素(薄膜二极管,包含硅的PIN结的光电转换元件或硅电阻元件)粘合到柔性膜上以提供更轻的半导体器件和 其制造方法。 (解决方案)当在基板上设置金属层11时,设置与金属层11接触的氧化物层12,形成被剥离层13,并且用激光束照射金属层11 进行氧化并形成金属氧化物层16,通过金属氧化物层12内的物理手段或金属氧化物层16与氧化物层12之间的界面,可以进行清晰的分离。
