Patent ID: 6939782

Claim:
A method for producing a thin layer incorporating at least one component or component part comprising: preparation steps comprising forming first and second added layers on first and second substrates respectively, wherein at least a part of each added layer can be locally weakened, wherein each of the first and second substrates and an associated part of the added layer to be weakened comprise different materials or different microstructures or both different materals and microstructures, weakening steps wherein in each of the first and second added layers a fragile sub-layer is created in each part to be weakened, work steps wherein complementary parts of the component or the component part are made on the first and second added layers, a joining step wherein the first and second substrates are assembled head to tail with the complementary parts of the component facing one another, and a separation step, a portion of which may take place between the weakening steps and the joining step, wherein a detachment is induced in the weakened parts along the fragile sub-layers, ultimately to obtain a thin layer incorporating at least the component or the component part.
