Abstract

PROBLEM TO BE SOLVED: To make avoidable the peeling of a deposited film and the deterioration of a vacuum atmosphere by using titanium as the material of a substrate holder which holds a substrate when at least a magnetic film is formed on the substrate by sputtering. SOLUTION: Titanium is used as the material of jigs located near a sputtering target 7 and exposed to considerable film deposition, e.g. a substrate holder 2, a substrate shield 3 and a ground shield 4 and the jigs are preferably subjected to low gas emission treatment, in particular treatment with a sulfuric acid-base acid bath. Before or after the treatment, the surfaces of the jigs are preferably roughened by a method such as sandblast. A controlled oxide is formed on the surfaces of the jigs by the acid bath treatment and films deposited by the scattering of a sputtering target material are removed. An Al alloy chemically polished with a treating soln. consisting essentially of sulfuric acid and phosphoric acid is used as the material of a chamber wall shield 5 and other parts exposed to relatively slight film deposition.

2. Description of the Related Art A thin film type magnetic recording medium is manufactured by forming a base film, a magnetic film, a protective film and other necessary films on a non-magnetic substrate by a sputtering method. At this time, the substrate is held by the substrate holder. Generally, an additional jig (hereinafter collectively referred to as a substrate holder / jig) or an internal member of a sputtering apparatus located between or near the substrate holder and the other substrate holder or the substrate and the sputtering target, or the like, is generally used. An aluminum (Al) alloy material is often used.

[0003] In the sputtering process, it is inevitable that the sputtering target material scatters around the area other than the object to be formed (substrate surface or film surface; hereinafter, collectively referred to as substrate). The scattered matter adheres to peripheral substrate holders / jigs and internal members to form a film, and the film is laminated. When the thickness of the adhered film becomes large, it often peels off, and the peeled fragments often adhere to the surface of the substrate, thereby forming defects and lowering the yield after film formation.

When a magnetic recording medium is manufactured by a sputtering method, the substrate is generally heated before forming a base film and a magnetic film, and then undergoes a cooling process before forming a carbon protective film. Therefore, the substrate holder / jig and the internal member are repeatedly subjected to heating and cooling, and this cycle of heating / cooling promotes the separation of the adhered film of the substrate holder / jig and the internal member, which causes a deterioration in yield. .

In order to prevent the adhesion film from peeling,
Generally, the surfaces of the substrate holder / jig and the internal member made of an alloy material are roughened by sandblasting. However, since a porous oxide layer is formed on the surfaces of the substrate holder and jig and the internal member made of the Al alloy material roughened by sandblasting, such surfaces easily absorb moisture, and the amount of absorbed moisture is low. Increase. This surface releases moisture during the sputtering process and creates a vacuum atmosphere (cleanliness) in the sputtering chamber (or chamber).

[0006] In order to make it difficult to adsorb water and to reduce the amount of water released, a treatment such as electrolytic polishing can be performed.

[0007] When the heating temperature is high, the Al alloy material is easily deformed, which may cause trouble during the transfer of the substrate. In order to prevent this, it is necessary to increase the frequency of replacing the substrate holder / jig and the internal member, but this leads to an increase in cost, which is not preferable.
