A substrate and a delamination film are separated by a physical means, or a mechanical means in a state where a metal film formed over a substrate, and a delamination layer comprising an oxide film including the metal and a film comprising silicon, which is formed over the metal film, are provided.
A substrate and a delamination film are separated by a physical means, or a mechanical means in a state where a metal film formed over a substrate, and a delamination layer comprising an oxide film including the metal and a film comprising silicon, which is formed over the metal film, are provided. Specifically, a TFT obtained by forming an oxide layer including the metal over a metal film; crystallizing the oxide layer by heat treatment; and performing delamination in a layer of the oxide layer or at both of the interface of the oxide layer is formed.
