Patent ID: 7422935

Claim:
A method for manufacturing a semiconductor device comprising the steps of: forming a peeling layer selectively over a first substrate wherein a portion of said first substrate is not covered by said peeling layer; forming a first insulating layer over said peeling layer and said portion of the first substrate; forming a thin film transistor including at least a source region and a drain region over the insulating layer; forming a second insulating layer over the first insulating layer and the thin film transistor; forming a first opening in the first insulating layer and the second insulating layer for exposing a part of the first substrate; forming a second opening in the second insulating layer for exposing one of the source region and the drain region of the thin film transistor; forming a first conductive layer over the second insulating layer, wherein the first conductive layer fills the first opening and the second opening; forming a third opening in the first insulating layer and the second insulating layer for exposing the peeling layer; introducing etchant to the third opening for removing the peeling layer; peeling a stacked body including at least the thin film transistor, the second insulating layer and the first conductive layer from the first substrate; and attaching the stacked body to a second substrate so that the first conductive layer is electrically connected to a second conductive layer provided over the second substrate.
