To provide a chip having a memory and the like and having a thin-film integrated circuit thin like paper mounted; to provide an extremely thin integrated circuit that uses the chip, has a label attached thereto, and can be mass-produced at a low cost; and to provide a formation method thereof.
This thin-film integrated circuit is formed by a method that can form a pattern selectively, on a glass substrate, a quartz substrate, a stainless substrate, a substrate made of a synthetic resin having flexibility, such as acrylic, or the like except for a bulk substrate. Further, a semiconductor apparatus with the thin-film integrated circuit and an antenna mounted is formed. Thereby, problems wherein an IC card is more expensive than a magnetic card, and an electronic tag is also more expensive as a substitute for bar codes can be solved.
