Claim Text:
1. A method of fabricating a thin-film transistor, the method comprising: a) film-forming an active layer, that contains as a main component thereof an oxide semiconductor structured by O and at least two elements among In, Ga and Zn, in a film formation chamber into which at least oxygen is introduced, and b) heat treating the active layer at less than 300° C. in a dry atmosphere, wherein the film-forming a) and the heat treating b) are carried out such that, given that an oxygen partial pressure with respect to an entire pressure of an atmosphere within the film formation chamber in the film-forming a) is PO wherein a number of H wherein the dry atmosphere is a condition wherein a moisture content of an entire atmosphere in the film formation chamber is less than or equal to an absolute humidity of 0.21 g/m
