Abstract:
1. A method for manufacturing a semiconductor device comprising the steps of: selectively forming a release layer over a first substrate; forming a first insulating layer over the first substrate with the release layer interposed therebetween; forming a plurality of thin film transistors over the first insulating layer; forming a second insulating layer over the first insulating layer; forming a first opening portion in the first insulating layer and the second insulating layer so that a portion of the first substrate is exposed; forming a second opening portion in the second insulating layer so that at least one of source and drain regions of the plurality of thin film transistors is exposed; forming a first conductive layer for filling the first opening portion and a second conductive layer for filling the second opening portion; forming a third opening portion in the first insulating layer and the second insulating layer to expose a portion of the release layer; removing the release layer by introducing etchant into the third opening portion; attaching the plurality of thin film transistors to a second substrate so that the second conductive layer is connected to a third conductive layer provided over the second substrate; separating the plurality of thin film transistors from the first substrate; and attaching the plurality of thin film transistors to a third substrate so that the first conductive layer is connected to a fourth conductive layer provided over the third substrate.
