安井学、平林康男、藤田博之, 表面技術, 2001, Vol.52, No.11, pp.734-735
以下、図面を参照して、本発明の電気部品の製造方法の好ましい一例を説明する。まず、図1の模式的断面図に示すように、導電性を有する基板1の表面全体にレジスト2を塗布する。ここで、基板1としては、ステンレス、銅またはアルミニウムなどの導電性の基板を用いてもよく、シリコンまたはガラスなどからなる非導電性基板上にチタン、アルミニウム、銅またはこれらの合金からなる導電層をスパッタリングなどにより形成したものを用いてもよい。また、レジストとしては、たとえばPMMA(ポリメチルメタクリレート)のような炭素と水素とを含む樹脂が用いられる。
以下に、図面を参照して、本発明のコンタクトプローブの製造方法の好ましい他の一例を説明する。まず、図10の模式的断面図に示すように、金属層6の表面に形成された金属酸化膜を除去することまでは上記の実施の形態1と同様である。次に、図11の模式的断面図に示すように、金属層6の表面上に酸化防止部材11を設置する。ここで、酸化防止部材11は金属層6の表面の酸化を防止することができるものであれば特に限定されず、たとえば銅などの金属を電気めっきすることによって形成される。
ステンレスからなる基板の表面全体にPMMAからなるレジストを塗布し、このレジストの一部にX線であるSR光(シンクロトロン放射光)を照射した後にその照射部分のレジストを除去することによって基板の表面を露出させ、幅60μm、長さ1mmおよび深さ60μmの除去部分を有する凹パターンにレジストが形成された。
<電解液の組成>
スルファミン酸ニッケル:600g/L
塩化ニッケル:10g/L
ホウ酸:40g/L
上記のように電鋳を行なって基板上にニッケル層を析出させた後に、レジストの表面から上方にはみ出しているニッケルを研磨して除去することによって、ニッケル層とレジストの表面の表面の高さを揃えた。そして、ニッケル層の表面に市販の強酸系の表面処理剤(キザイ株式会社製「コケイサンRP」)を塗布することによって、研磨によりニッケル層の表面に形成されたニッケル酸化膜を除去した。続いて、酸素と四フッ化炭素との体積比が1:1である混合ガスを用いて、以下の条件によりアッシングを行ない、レジストを除去した。
<アッシングの条件>
混合ガス圧:0.5torr
電力:100W
処理時間:200分
上記のアッシング後にニッケル層を基板から取り外して得られた電気部品について、表面のAES分析(オージェ電子分光法)を行なったところフッ素は検出されなかった。次に、電気部品の表面に対して、下記めっき条件で電気めっきを行なったところ、表面全面に良好なロジウムめっき膜が形成された。これらの結果から、本実施例においては、ニッケルフッ化膜の生成を防止できたことが確認され、また、ムラのない良好なロジウムめっき膜を有する電気部品を得ることができた。なお、下記めっき条件において、めっき浴を構成する成分として、下記の組成に表記されている成分以外はすべて水である。
<めっき条件>
めっき浴:硫酸ロジウム 1.5g/L
硫酸 20ml/L
浴温:50℃
電流密度:2A/dm2
陽極:白金板
時間:100秒
(実施例2)
実施例1と同様にして、電鋳により母型のステンレスからなる基板上にニッケル層を析出させた後にニッケル層を研磨することによって、ニッケル層とレジストの表面の高さを揃えた。そして、実施例1と同様の表面処理剤を用いることによってニッケル層の表面のニッケル酸化膜を除去した後に、ニッケル層の表面に対して酸化防止部材として銅めっき膜を3μmの厚さで形成した。その後、実施例1と同様の条件でアッシングを行なうことによってレジストを除去した。
研磨によってニッケル層の表面に形成されたニッケル酸化膜を除去しなかったこと以外は実施例1と同様にして電気部品を製造した。その後、この電気部品について実施例1と同様にAES分析を行なったところ、電気部品の表面から2nm程度の厚みにおいてフッ素が検出された。
比較例1と同様の条件で、アッシングまで実施した表1に示すサンプルNo.1〜No.6の各サンプルに対し、表1に示す各種表面処理剤を用いためっき前処理を行ない、金属層の表面に生成したフッ化ニッケル膜の除去を試みた。そして、めっき前処理を行なった各サンプルについて実施例1と同様のめっき条件でめっきを行なった。表1に、その前処理の条件とめっきの結果を示す。なお、表1において、「%」は質量%のことを意味し、「処理温度」は表面処理剤の温度のことを意味し、「処理時間」はニッケル層の表面処理剤への浸漬時間のことを意味する。また、表1において、めっき結果が「×」である表記はめっきができなかったことを意味している。
