Abstract
A method of manufacturing a semiconductor device, comprises the steps of: forming a first insulating film on a first substrate; forming a second insulating film on the first insulating film; forming an amorphous silicon film on the second insulating film; holding a metal element that promotes the crystallization of silicon in contact with a surface of the amorphous silicon film; crystallizing the amorphous silicon film through a heat treatment to obtain a crystalline silicon film; forming a thin-film transistor using the crystalline silicon film; forming a sealing layer that seals the thin-film transistor; bonding a second substrate having a translucent property to the sealing layer; and removing the first insulating film to peel off the first substrate.
