Title: Anodic oxidation and device therefor
Inventor: ISHIBASHI MASAYUKI
IPC: H01L21/316
Filed: 1993-05-31
Abstract: PURPOSE:To perform the anodic oxidation and to provide a device therefor, with which anodic oxidation can be performed without generating pinholes even when the liquid level of the electrolytic solution fluctuates by anodically oxidizing initially covering a wide region of and thereafter within a narrower region of the substrate to be oxidized at the time of dipping a metallic film formed on the insulating substrate in the electrolytic solution and subjecting the film to anodic oxidation. CONSTITUTION:The anodic oxidation of the metallic film on the substrate is performed by circulating the electrolytic solution 3 in the oxidation vessel 1 provided with the overflow tank 2 through the orifice 5 and the valve 6 placed in parallel by using the circulating pump 4 and passing through current between the cathode plate 9 and the substrate to be oxidized 7 mounted on the substrate receiving base 13 from the D.C. power source 8. At this time, the liquid level 10 of the electrolytic solution 3 is raised by setting the valve 6 to the 'opened' position in the initial stage of the oxidation to increase the circulating amount of the electrolytic solution 3. Thereafter, when most of the oxide film is formed, the liquid level 10 is lowered by about 1 to 2mm by setting the valve 6 to the 'closed' position and allowing the electrolytic solution 3 to flow exclusively through the orifice 5 to decrease the circulating amount of the electrolytic solution 3 and to prevent the contact of the electrolytic solution 3 with the unoxidized part of the metallic film due to the fluctuation of the liquid level 10 of the solution 3 from occurring. Thus, the anodic oxidation of the metallic film formed on the substrate 7 can be performed without generating pinholes.
