A film forming method by plasma sputtering is provided to attain a composite film on a substrate. A target plate having metal materials in a different pattern is prepared in opposition to the substrate. A plasma is created by a planar magnetron sputtering electrode structure. The plasma is shifted magnetically on the target plate by at least three magnetically coupled magnetic poles to deposit the materials into a film with a uniform thickness and a desired composition on the substrate.

A target for use in a sputtering technique usually has a flat structure. The present invention has succeeded in endowing sputtering film formation with a directivity in such a way that the surface of the target is provided with recesses thereby to limit the flight directions of sputtering particles.Alternatively, the directivity can be bestowed by disposing a frame between a substrate to be formed with a film and the flat sputtering target. This measure requires auxiliary means in which a wall is provided at the outer periphery of the sputtering target so as to effectively utilize a plasma.The present invention actually formed films by the use of the above technique, and has verified the effect thereof. Wide applications are expected in technical fields wherein after forming a microscopic pattern, one or more films need to be further formed.
摘要:
A sputtering apparatus of the planar magnetron type is disclosed, in which a low-pressure gas is ionized by glow discharge, ions in the plasma are accelerated by a voltage applied between a cathode and an anode to bombard a target structure, atoms or particles of a target material sputtered from the planar target plate by the bombardment of ions are deposited on a substrate disposed on the anode side, and thus a thin film made of the same material as the target material is formed on the substrate. In view of the facts that lines of magnetic flux generated by a single magnetic flux source does not link each other and the Maxwell stress, the target structure includes the planar target plate and a magnetic flux source having at least three pole pieces in an arrangement that the planar target plate is disposed between the anode and the magnetic flux source, and the amount of magnetic flux starting from a portion of the pole pieces is controlled to control the amount of magnetic flux (or the flux density) existing at the remaining pole pieces and the magnetic flux distribution above the planar target plate, thereby controlling the position of a region where the plasma is formed.

摘要:
A base plate for magnetic recording disc is produced by coating thin metal layers containing no impurities for forming defects by an anodizing treatment on one or both sides of a discoid substrate made of a metal such as aluminum or an aluminum alloy or from a plastic by a dry process, and anodizing the thin metal layers so as to form anodized film from the surfaces of the thin metal layers to a certain depth while the portions contacting to the substrate are retained not anodized.
摘要:
Planar magnetron sputtering sputters a target formed of plural target members from their principal surface. The plural target members are arranged on an electrode. The sputtering is carried out in such a condition that an electric field and magnetic field are substantially parallel in their direction at the boundary regions among the plural target members.
