    摘要: The present invention provides a pattern forming method including the steps of forming a first thin film on an object to be etched, forming a first surface region and a second surface region on a surface of the object by modifying or removing a portion of the first thin film, the first and second surface regions differing from each other in the surface state, forming a second thin film on the first surface region by utilizing the difference in the surface state between the first and second surface regions, the second thin film being amorphous and thicker than the first thin film, and etching the object using the second thin film as an etching mask.
