Patent ID: 6878607

Claim:
A method for making a circuit, comprising: a first step of forming a first separation layer on a substrate; a second step of forming an object-of-transfer layer including a device on said first separation layer; a third step of forming a second separation layer on said object-of-transfer layer; a fourth step of attaching a primary destination-of-transfer part to said second separation layer; a fifth step of causing exfoliation in an inner-layer and/or interface of said first separation layer, and then removing said substrate from said object-of-transfer layer while retaining at least part of said first separation layer on said object-of-transfer layer using said first separation layer as a boundary; a sixth step of removing said first separation layer from said object-of-transfer layer; a seventh step of attaching a secondary destination-of-transfer part to the bottom of said object-of-transfer layer; and an eighth step of removing said primary destination-of-transfer part and said second separation layer from said object-of-transfer layer, wherein said circuit includes said object-of-transfer layer including the device transferred to said secondary destination-of-transfer part.
