Abstract
A thin-film device is fabricated by forming a protective layer and a thin-film device layer one by one on a first substrate and bonding a second substrate on the thin-film device layer via a first adhesive layer or a coating layer and first adhesive layer, removing the first substrate at least in a part thereof by etching with a chemical solution, bonding the protective layer, which covers the thin-film device layer on a side of the first substrate, to a third substrate via a second adhesive layer, and removing the second substrate. The protective layer is formed of at least two layers having resistance to the chemical solution used upon removal of the first substrate.
