    Abstract: PROBLEM TO BE SOLVED: To provide a powder compacting metallic die for compacting powder containing high hardness powder, such as oxide powder, magnetic metal powder, which die is excellent in friction wear resistance and shock resistance, and further to provide its manufacturing method. SOLUTION: At least the surface of the die at the portion for pressing the powder is composed of at least a rough surface or a mixed layer of an electrode and a base material of the die caused by electric discharge machining, and an amorphous carbon based hard layer which has residual stress lower than 0.3 GPa or less and is formed on the rough surface or the mixed layer. By this configuration, the powder compacting metallic die can achieve high hardness, high wear resistance, smooth surface, a low frictional coefficient, excellent die releasing property, excellent chemical resistance/corrosion resistance, excellent slidability, and further improved shock resistance.

    Abstract: 【課題】従来の技術では、定盤との接触によるウエハホルダの磨耗や、砥粒や研磨剤のウエハホルダに対する影響を防ぐことができない、という第一の課題がある。 また、金属製のウエハホルダの場合、ポリッシング研磨の際に供給される研磨剤により内部の金属イオンが外部に流出する、という第二の課題もある。
    【解決手段】以上、第一および第二の課題を解決するために、研磨装置の定盤に対してウエハを保持するためのウエハホルダであって、ウエハ配置穴があけられ、少なくとも一部または全部がDLCコーティングされている円盤体からなるウエハホルダを提供する。 また、上記円盤体を、円盤状本体と、ウエハ配置穴を形成し円盤状本体に対して着脱可能としたウエハ配置リング部とから構成し、前記ウエハ配置リング部の厚さを、前記円盤状本体の厚さよりも厚く構成するウエハホルダも提供する。

    Abstract: PROBLEM TO BE SOLVED: To form a thick DLC (diamond-like carbon) film on a surface of a base material to reduce the residual stress in the film.
    SOLUTION: A base material to be coated is placed in a vacuum container filled with hydrocarbon-based gas, the pulse RF voltage and the high-voltage DC pulse voltage of negative polarity are alternately applied to the base material, the DC pulse voltage is applied after completion of application of the pulse RF voltage, and the pulse-height value of the DC pulse voltage is set to the threshold voltage transferred to the glow discharge. The hydrocarbon-based gas is toluene gas, the gas pressure is set to be 0.1-2 Pa, and the DC pulse voltage is applied in 10-50 μs after completion of application of the pulse RF voltage. The DLC film having the residual stress of the coated base material, which is 0-0.5 GPa is provided. The DLC film having thickness of 1-40 μm is provided.
