Abstract

The disclosure discloses a method for roughening a surface of a metal layer, a thin film transistor, and a method for fabricating the same. The method for roughening the surface of a metal layer includes: forming a first photo-resist layer on the surface of the metal layer, and processing the first photo-resist layer at high temperature; and stripping the first photo-resist layer to roughen the surface of the metal layer.
