C2H2, and films 2 of TiC or the like are formed on the surfaces of the substrate 1 by a reactive film forming method such as ionic plating using a titanium group metal such as Ti, Zr, Hf or W. Layers 3 of a recording medium are then formed on the films 2 to obtain a magnetic disk. The carbide of the metal is hard and dense and undergoes little change with the lapse of time, and since the intermediate layers 2 of the carbide are present, the resulting disk has wear resistance and undergoes little change with the lapse of time. The surfaces of the films 2 may be oxidized by anodic oxidation or other method to form thin TiO2 films 4. By forming the films 4, the chemical stability to heat generation at CS/S is improved.

IPC: C23F1/08
Filed: 1999-01-29
Abstract: PROBLEM TO BE SOLVED: To provide a small substrate processing system for etching a substrate well at low cost and a substrate processing method for etching a substrate well at low cost. SOLUTION: After removing organic substances adhering to the surface of a substrate by irradiating it directly with UV rays, the substrate is carried to an etching section 10C by means of a carrying robot 16a and subjected to etching. Consequently, the time to be elapsed after completing removal of organic substances before starting etching is shortened and etching can be carried out with excellent uniformity. Since the substrate is irradiated directly with UV-rays in order to remove organic substances, many problems including complication of system and process, increase in the running cost, and increase in the number of points requiring exhaust countermeasure can be solved at once as compared with a case where organic substances are removed by supplying an organic substance removing solution, e.g.  APM (mixture solution of ammonia and hydrogen peroxide water) or SPM (mixture solution of sulfuric acid and hydrogen peroxide water).
