Method of forming slope by use of laser ablation technique, method of forming recessed portion, method of manufacturing organic thin film tranasistor, and organic thin film transistor manufactured by the method

摘要

The present invention is a laser ablation technique the method for forming the inclined surface, a method of forming the grooves, a method for producing an organic thin film transistor and a method using which a vertical step of etching the surface of the object does not form to facilitate the subsequent process to an organic thin film transistor manufactured by, further etching the object by irradiating a laser beam on at least a portion of the surface of the object, by the intensity of the laser beam to reach the said area so as to gradually turn into, it is formed surface slope using laser ablation technique, characterized in that to ensure that there is provided a method of forming a method of forming grooves and method for forming the inclined surface.
