Abstract

A metal oxide film and a manufacturing method thereof, a thin film transistor and an array substrate are provided. The manufacturing method of the metal oxide film includes: forming a metal oxide film on a base substrate; and supplying a negative ion to the metal oxide film for a preset time period by performing a anodization method, to convert a portion of metal ions in the metal oxide film into a metal oxide.
