Abstract

A method for processing a polysilicon thin film and a method for fabricating a thin film transistor are provided. The method for processing a polysilicon thin film includes: etching the polysilicon thin film using etching particles. An angle between an incident direction of the etching particles and the polysilicon thin film is larger than 0° and less than 90°.
