(4)ジンケート処理の前に自己集積化単分子膜を露光により除去する工程を含む、(1)〜(3)のいずれかに記載の方法。
(5)アルミニウム材料からなる基材に(1)〜(4)のいずれかに記載の方法によりめっき前処理を行うめっき前処理工程と、基材上にめっき処理を施すめっき処理工程とを含む、アルミニウム材料の部分めっき方法。
(6)めっきがニッケルめっきである、(1)〜(5)のいずれかに記載の方法。
(7)ノナフルオロヘキシルトリメトキシシランとトリフルオロプロピルトリメトキシシランの混合物を含む、アルミニウム材料のめっき用レジスト。
(8)ノナフルオロヘキシルトリメトキシシランとトリフルオロプロピルトリメトキシシランの混合比が4:6〜6:4である、(7)のレジスト。
(1)成膜工程
基材として高純度アルミニウム板を用いた。基材は、超音波洗浄後、真空紫外光(VUV)を照射して表面をOH化してから試験に用いた。自己集積化単分子膜(SAM)の原料と基材とをテフロン(登録商標)製の密閉容器中に封入し、200℃で3時間加熱した後にSAMが形成された基材を取り出し、超音波洗浄した。SAMの原料としてはFAS9とFAS3の混合液、あるいはFAS13、FAS9またはFAS3をそれぞれ単独で用いた。各原料の化合物名と示性式は以下のとおりである。
FAS9:ノナフルオロヘキシルトリメトキシシラン(CF3(CF2)3(CH2)2-Si(OCH3)3)
FAS3:トリフルオロプロピルトリメトキシシラン(CF3(CH2)2-Si(OCH3)3)
FAS13:トリデカフルオロオクチルトリメトキシシラン(CF3(CF2)5(CH2)2Si(OCH3)3)
SAMを成膜した基材に対し、めっきを析出させたい部分のSAMを除去するために真空紫外光を照射した。
第一亜鉛置換処理として、アルモンEN(メルテックス社製)200mL/L水溶液(pH≒14)に基材を浸漬した。次に、基材を34%硝酸水溶液に浸漬して亜鉛剥離処理を行った後、第二亜鉛置換処理として、アルモンEN200mL/L水溶液(pH≒14)に基材を再度浸漬した。
基材をメルプレートNI−4990(メルテックス社製)に浸漬し(82℃、pH=7)、無電解ニッケルめっき処理を行った。めっき厚は5μmであった。
(1)SAMのめっき析出抑制効果
上記手順(露光工程を除く)に従ってめっき処理を行ったものについて、SAMを成膜しなかった場合のめっき析出重量に対するめっき析出重量率を求めた。また、めっき処理後のSAMの水接触角を測定した。
上記1の(1)の手順に従って基材に成膜したSAMの表面のXPSスペクトルを測定した。FAS9単独、FAS3単独、およびFAS9とFAS3の混合液(FAS9に対するFAS3の混合モル比50%)を用いて成膜したそれぞれのSAMから得られたスペクトルを図3に示す。FAS9とFAS3の混合液を用いた場合に得られたスペクトルは、それぞれを単独で用いた場合に得られたスペクトルを足し合わせたような形状であった。従って、FAS9とFAS3の混合液を用いた場合には、FAS9とFAS3とが混合した構造を有するSAMが得られているものと考えられる。
成膜したSAMの真空紫外光(VUV)の照射による除去しやすさを確認するため、VUV照射後の水接触角を測定した。照射時間と水接触角の関係を示すグラフを図4に示す。FAS9とFAS3の混合液(FAS9に対するFAS3の混合モル比50%)を用いて成膜したSAMでは、FAS9およびFAS3を単独で用いて成膜したSAMにおいて得られたそれぞれの値の中間の水接触角を示し、それぞれを単独で用いた場合の中間の除去し易さを有することがわかった。従って、FAS9/FAS3混合SAMは、VUVにより酸化分解させて除去することができ、光除去可能なめっきレジストとして利用可能であると考えられる。
