Patent ID: 7632740

Claim:
A method for manufacturing a semiconductor device, comprising the steps of: forming a first peeling layer comprising a silane coupling agent over a first substrate; forming a first conductive layer over the first peeling layer; forming a first insulating layer covering the first conductive layer; peeling the first conductive layer and the first insulating layer from the first substrate; attaching a second substrate to the first conductive layer and the first insulating layer; forming a second peeling layer comprising a silane coupling agent over a third substrate forming a second conductive layer over the second peeling layer; forming a second insulating layer covering the second conductive layer; peeling the second conductive layer and the second insulating layer from the third substrate; attaching a fourth substrate to the second conductive layer and the second insulating layer; forming a sealant over the second substrate or the fourth substrate; coating a region surrounded by the sealant with a liquid crystal material; and attaching the second substrate having the first conductive layer and the first insulating layer and the fourth substrate having the second conductive layer and the second insulating layer with the sealant.
