A thin-film semiconductor crystal is formed by depositing a thin film of amorphous silicon on a substrate, introducing ions selectively into a predetermined region of the thin film of amorphous silicon, and growing a single semiconductor crystal in the thin film of amorphous silicon by way of solid-phase crystal growth. A semiconductor device which employs the thin-film semiconductor crystal has a channel in the region where the ions are selectively introduced.
