Abstract:
1. A method for manufacturing a semiconductor device comprising the steps of: forming a peeling layer over a substrate; forming a first insulating layer over the peeling layer; forming a transistor over the first insulating layer; forming a second insulating layer over the transistor; forming a first conductive layer connected to a source or a drain of the transistor through an opening provided in the second insulating layer; forming a second conductive layer containing a conductive particle and resin over the first conductive layer; increasing an area where the first conductive layer and the second conductive layer are in contact with each other by irradiating the second conductive layer with a laser beam; selectively forming a third insulating layer so as to expose part of the second conductive layer over the second insulating layer and the second conductive layer; forming such an opening that the peeling layer is exposed by irradiating the second insulating layer and the third insulating layer with a laser beam; and separating a stacked body including the transistor from the substrate by using the inside of the peeling layer or the interface between the peeling layer and the first insulating layer as a boundary.
