Abstract:
1. A method for forming an insulating film, the method comprising: forming a film containing an organic curable material on a substrate; irradiating a low energy plasma having an electron temperature of 2 eV or less and produced by a microwave irradiation through a planar antenna member having a plurality of slits to thereby cure the film containing the organic curable material and form the insulating film having a dielectric constant of 3 or less; and controlling a temperature of the antenna member by using a temperature controlling member to be set in a temperature range, wherein said controlling comprises controlling the temperature of the antenna member to be in a range from 60° C. to 80° C. in order to improve uniformity of a density of the plasma and to improve quality of the insulating film.
