Patent ID: 7736964

Claim:
A method for manufacturing a semiconductor device comprising: forming selectively a peeling layer over a first substrate; forming a layer having a plurality of thin film transistors over the peeling layer; forming a first opening so that a part of a semiconductor film of the thin film transistors is exposed and forming a second opening in the peeling layer so that the first substrate is exposed; forming a first conductive film at the first opening and the second opening; processing the first conductive film to form a source or drain electrode at the first opening and to form a wiring at the second opening; forming a third opening so that the peeling layer is exposed; introducing an etching agent into the third opening and removing the peeling layer to separate the layer having the plurality of thin film transistors from the first substrate; and pasting the layer having the plurality of thin film transistors onto a second substrate so that the wiring and a second conductive film provided over the second substrate are electrically connected to each other through a plurality of places.
