摘要： A method of forming a gate insulation film 4 comprising a hafnium silicate material with a SiO2 equivalent oxide thickness of 1.45 nm or less on a silicon substrate 1 is disclosed. The method includes the steps of: cleaning a surface of the silicon substrate 1 to establish thereon a clean surface on which substantially no oxygen is present; forming a hafnium silicate film 2 on the clean surface of the silicon substrate 1 by a CVD process using an amide type organic hafnium compound and a silicon-containing raw material; applying an oxidation treatment to the hafnium silicate film 2, and applying a nitriding treatment to the hafnium silicate film 2 after applying the oxidation treatment. According to the method, a gate insulation film with favorable surface roughness can be obtained even if the film thickness is thin.
