Abstract
The present application discloses an oxide semiconductor thin-film and a thin-film transistor consisted thereof. The oxide semiconductor thin-film is fabricated by doping a certain amount of rare-earth oxide (RO) as light stabilizer to metal oxide (MO) semiconductor. The thin-film transistor comprising a gate electrode, a channel layer consisted by the oxide semiconductor thin-film, a source and drain electrode; the thin-film transistor employing etch-stop structure, a back-channel etch structure or a top-gate self-alignment structure.
