Patent ID: 8236125

Claim:
A method for manufacturing a thin film multilayer device including a plastic substrate and a plurality of thin films stacked on the plastic substrate, comprising: a first step of preparing a plastic substrate on which a first inorganic film and a second inorganic film are stacked in this stated order; a second step of bonding the plastic substrate to a support substrate using an adhesive so that the first and second inorganic films are sandwiched between the plastic substrate and the support substrate, and the plastic substrate is supported by the support substrate with an adhesive force stronger than an adhesive force between the first and second inorganic films; a third step of stacking a plurality of thin films on the plastic substrate supported by the support substrate; and a fourth step of separating the first inorganic film from the second inorganic film to separate the plastic substrate on which the plurality of thin films are stacked, from the support substrate.
