Abstract: PURPOSE:To make uniform a nitriding of a sputtered film and a target and to stabilize the electric resistance of the sputtered film by a method wherein the target consisting of a high-melting point material and a wafer holder consisting of a high-melting point material are installed in the chamber of a puttering device and a heating unit is installed in parallel to the surface to be sputtered of the target and at a position, where the target and the wafer holder are heated from the side surfaces of the surface to be sputtered. CONSTITUTION:A target 2, a shutter plate 1 and a wafer holder 4 are installed at positions, where they are heated from the side surfaces of the surface to be sputtered of the target 2, and an electric furnace 14 which is heating unit is installed at a position parallel with the surface to be sputtered of the target 2. The temperature on the peripheries of the target 2 and a wafer 3 is heated up by this furnace 14 to 1000 deg.C or thereabouts and a sputtering is performed in an atmosphere containing the mixed gas of nitrogen gas and argon gas. Thereby, a titanium nitride film can be formed on the wafer 3 at a high temperature of 1000 deg.C of thereabouts. As a result, a heat treatment for stabilizing the film quality of the titanium nitride film after the formation of the titanium nitride film becomes unnecessary and the deterioration of the film quality due to oxidation can be also simultaneously prevented.
