Abstract

The present invention is made to solve a problem to improve adhesion between a fluorine-containing carbon film and a foundation film. In order to achieve this object, according to the present invention, a fluorine-containing carbon film forming method of forming a fluorine-containing carbon film on a to-be-processed substrate includes: a first process of carrying out plasma excitation of a rare gas, and carrying out a surface treatment of the to-be-processed substrate with the use of the thus-plasma-excited rare gas with a substrate processing apparatus; and a second process of forming the fluorine-containing carbon film on the to-be-processed substrate, wherein the substrate processing apparatus has a microwave antenna electrically connected to a microwave power source.
