Abstract
Description
溶融したニッケルクロム合金およびダイヤモンド粒子でステンレス鋼の表面に研磨層を形成し、溶融したニッケルクロム合金を表面張力によって各ダイヤモンド粒子の斜め側面の一部に覆われ、前記ダイヤモンド粒子を埋め込んで支持し、固定する。プラズマ法で各ダイヤモンド粒子の突起の絶縁処理を施して、前記突起の表面を絶縁させる。最後に、エポキシ樹脂(米インダストリーズ社(PPG)製)を結合層の表面に電着して、保護層を形成させ、本発明の研磨パッドドレッサーを得た。
比較例1の研磨パッドドレッサーの製造方法は、実施例と同じで、その相違点は比較例1が各ダイヤモンド粒子の突起に対し絶縁処理を施していないことである。
走査型電子顕微鏡(SEM)で実施例および比較例1の研磨パッドドレッサーの研磨層表面を撮影した結果を図4に示す。図4(a)は、比較例1の研磨パッドドレッサーの研磨層表面であり、図4(b)は実施例の研磨パッドドレッサーの研磨層表面である。図4(b)に示すように、実施例の研磨パッドドレッサーの研磨粒子の突起は、絶縁処理を施したことにより、保護層を表面に電着させることができないため、鋭利な刃先を持つ。対照的に、図4(a)に示すように、比較例1の研磨パッドドレッサーの研磨粒子の突起は、絶縁処理を施しておらず、保護層が表面に電着されているため、刃先が鈍いため鋭利な刃先を持っていない。
溶融したニッケルクロム合金およびダイヤモンド粒子でステンレス鋼の表面に研磨層を形成し、溶融したニッケルクロム合金を表面張力によって各ダイヤモンド粒子の斜め側面の一部に覆われ、前記ダイヤモンド粒子を埋め込んで支持し、固定すると、保護層のない研磨パッドドレッサーを得た。
