Abstract:
A method for manufacturing a field-effect transistor includes forming an active layer of an oxide semiconductor, forming a conducting film to cover the active layer, patterning the conducting film through an etching process using an etchant to form a source electrode and a drain electrode, and performing, at least before the patterning the conducting film, a treatment on the active layer so that an etching rate of the active layer is less than an etching rate of the conducting film.

Claim (Index 31):
The method according to  claim 29 , wherein the oxide semiconductor contains at least one element selected from the group consisting of rare earth elements, Al, Zr, and Hf.
