る。Conventionally, stampers used for manufacturing optical disks and video disks have been manufactured by the method shown in FIG. 1 (al to Tel). That is, as shown in FIG. As film 2,
As shown in FIG. 1 (BL), a pattern 3 of a predetermined shape is formed by a normal photo process. Next, as shown in FIG. Next, as shown in JIEI diagram Fdl, a plating MIs such as a nickel plating film is formed using the metal thin M4 as a conductive film by a normal electroplating method.After plating, as shown in FIG. By peeling off at the interface of 2, a stamper having a pattern that is an inversion of the notches formed in the photoresist can be obtained.
金柑薄膜4は、スタンパのスタンピング面として使用さ

酸化されやすい性質を有している。その次め、蒸着等の
気相成長装置から取出したとき、金属薄膜の表面が空気
中の酸素により容墨に酸化され酸化膜で被れてしまう。Since the kumquat thin film 4 is used as a stamping surface of a stamper, it is required to have hardness and abrasion resistance. For this reason, metals such as nickel, chromium, and tantalum are used for the metal thin film 4, but these metal thin films have a property that their surfaces are extremely easily oxidized. Next, when the metal thin film is removed from a vapor phase growth apparatus such as a vapor deposition apparatus, the surface of the metal thin film is extensively oxidized by oxygen in the air and is covered with an oxide film.
上記金属の酸化膜は強固かつ緻密である念め、通常の酸

酸化膜の形成され次金属薄膜上にめっき膜を形成すると
、めっき膜は金属薄膜と十分接着せず、接着力は数Kg
/cm’ +Na度にすぎない。The oxide film of the above-mentioned metals is strong and dense, and cannot be dissolved and removed by ordinary methods such as pickling. Therefore, when a plating film is formed on the metal thin film after the oxide film is formed, the plating film is Does not adhere well to metal thin film, adhesive strength is several kg
/cm'+Na degree.
このようにめっき膜と金属薄膜との接着力が小さいと、
金属薄jl[Fi一般に数1000λ程度の薄い膜であ

、接着力が極端に小さいときけ、金属薄膜とホトレジス
トの界面での剥離を行なう工程で金属薄膜がめつき膜か
ら剥れてし甘い、スタンパを製造できなくなってしオう
。If the adhesive force between the plating film and the metal thin film is small in this way,
Since the metal thin film is generally about several thousand λ, it peels off from the plating film during stamping, and the life of the stamper becomes extremely short. tt
If the adhesive strength is extremely low, the metal thin film will peel off from the plating film during the peeling process at the interface between the metal thin film and the photoresist, making it impossible to manufacture a stamper.
本発明の目的は、上記(2次従来技術の欠点をな。The object of the present invention is to overcome the drawbacks of the secondary prior art.

命の長い本のとし次ことに特徴がある。The stamper according to the present invention is formed by a vapor growth method such as vapor deposition, and then formed between a first metal thin film having a pattern of a predetermined shape and a plating film using the same vapor growth apparatus as the first metal thin film. By providing a second metal thin film that serves as an adhesive layer, the adhesion between the metal films constituting the resistor is improved, resulting in a book with a long life.
接着層となる第2の金属薄膜としては、空気中で酸化膜
の形成されにくい金属もしくけ酸化族が形成されても酸
洗等の手段で容易に除去できる金属であれば特に制限は
なく、例えば金、銀、鋼、亜鉛、スズ、鉛などがある。The second metal thin film serving as the adhesive layer is not particularly limited as long as it is a metal that is difficult to form an oxide film in the air or a metal that can be easily removed by pickling or the like even if a silicate group is formed. Examples include gold, silver, steel, zinc, tin, and lead.

まう。The thickness of the second metal thin film is preferably 0.01 to 10 μm. If the second metal thin film is less than 0.01) trn, the second metal thin film will not be formed as a complete film and most of it will be dissolved and removed in the pickling process before plating, and it will lose its effectiveness as an adhesive layer.

らべてめっき膜の均一性を向上させることができた。According to the present invention, the adhesion force between the gold JL films constituting the next stamper has been increased to 100 kg/cm, which is only a lace compared to the conventional number.
I was able to improve it to 2 or more. This allows the first step when stamping the system.
This eliminates the peeling of the metal thin film, making it possible to manufacture a stamper with an extremely long life.In addition, by providing the second metal thin M as an adhesive layer, the second metal thin film is bonded to the first metal thin film. Since the electrical conductivity is higher than that of a thin film, the current density from the start of plating until the plating thickness grows to about 1 μm is set at 0.05 AI, 3□2 to 0.5'/dm.
'The plating time can be shortened by about 2 hours. Furthermore, since the electrical resistance of the first and second metal thin films is small, the resistance value from the center to the periphery of the glass master plate, which is the current-carrying part, is small, which improves the uniformity of the plating film compared to conventional methods. did it.
