摘要： A low dielectric constant film containing a silicon, a carbon, an oxygen, and a hydrogen is formed on a substrate as a semiconductor wafer, and a resist film is formed on the low dielectric constant film. Then, the low dielectric constant film is etched with the use of the resist film as a mask to form an exposed surface of the low dielectric constant film. Next, there is deposited a protective film that covers the exposed surface of the low dielectric constant film formed by etching. Thereafter, by ashing with the use of a plasma containing an oxygen, the protective film and the resist film are removed. During the ashing, desorption of the carbon from an insulation film is restrained by the protective film.
