Abstract:
An oxide semiconductor film etching method includes the step of: preparing a substrate ( 1 ) with an oxide semiconductor formed on a surface thereof, the oxide semiconductor film ( 7 ) containing In, Sn, and Zn; and etching the oxide semiconductor film ( 7 ) using an etching solution containing ammonium fluoride.

Claim (Index 10):
The method for manufacturing a semiconductor device according to  claim 6 , wherein the semiconductor device comprises a thin-film transistor,\n wherein, in step (a), the oxide semiconductor film and the metal film are formed in this order on the surface of the substrate, wherein step (b) further comprises step (b-2) of removing part of the metal film by dry etching to expose a portion of the oxide semiconductor film, the portion of the oxide semiconductor film later serving as a channel region of the thin-film transistor, and wherein source and drain electrodes of the thin-film transistor are obtained from the metal film in step (b).
