Abstract

The present invention relates to a film forming method of forming a silicon containing insulating film by plasma CVD. Objects of the present invention are to form, using a highly safe reaction gas, an insulating film which is dense, has excellent step coverage and is low in moisture and in organic residues such as carbon. The insulating film has good affinity for the silicon oxide film formed by the thermal CVD method. The invention also enables control of the refractive index and stress etc. of the insulating film formed. The mixed gas, including the organic compound having Si-H bonds and the oxidizing gas, is converted to a plasma and the silicon containing insulating film is formed on a deposition substrate from the plasma.
