摘要:
An object of the present invention is to provide a novel semiconductor device which is excellent in stability, uniformity, reproducibility, heat resistance, durability and the like, and can exert excellent transistor properties. The semiconductor device is a thin-film transistor, and this thin-film transistor uses, as an active layer, a polycrystalline oxide semiconductor thin film containing In and two or more metals other than In and having an electron carrier concentration of less than 1×1018/cm3.
