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 4):
The method for etching an oxide semiconductor film according to  claim 1 , wherein the oxide semiconductor film comprises an In\u2014Sn\u2014Zn\u2014O-based oxide semiconductor, and the number of In atoms, the number of Sn atoms, and the number of Zn atoms in the In\u2014Sn\u2014Zn\u2014O-based oxide semiconductor satisfy the following formulas:\n 0.2<[In]/([In]+[Sn]+[Zn])<0.4; 0.1<[Sn]/([In]+[Sn]+[Zn])<0.4; and 0.2<[Zn]/([In]+[Sn]+[Zn])<0.7, where [In] is the number of In atoms, [Sn] is the number of Sn atoms, and [Zn] is the number of Zn atoms.
