Abstract
【解決手段】下地調整工程、紋様形成工程、修飾表面積層工程などを経て、基体表面上に選択的な機能性紋様を形成する方法において、当該紋様形成工程がA.当該基体と反応する反応液2を保持し、当該機能性紋様を有した凹版5を当該基体表面に当てて当該機能性紋様を転写する押圧過程、B.反応液をそのまま一定時間保持して当該基体表面の活性度を調整する活性化調整過程の2過程を経ることで、全面に表面修飾層を形成して直接に機能性紋様9を得る。基本的には鍍金後に紋様を蝕刻などしない。
【選択図】図2
Description
以下本発明では、先端的な実装基板を代表例として詳細な説明を行う。
原理的には、版5に乗せられた反応液2はその紋様で形状が限定されている為に、若干の滲み出しが有っても、正確に版5の形状を正確に写し取った表面変性層や表面粗化が達成される。
さらに本発明では、面積の非常に小さい回路パターンなどの紋様部分だけに鍍金する為に省資源であり、全面鍍金した金属を除去する余計な腐食液なども不要であることから、一層の省資源省エネとなっている。これらによるコスト低減効果も大きい。
なお、同様の手法をバイオデバイスや化学センサーなどにも適用でき、上記と同様な優れた特徴が得られることは云うまでも無い。
ポリイミド表面を加水分解する腐蝕液の増粘剤の量や種類を変えて、粘度を水のような1cpsからゆるい粘土の様な数万cpsまで作成して実験を行った。幅70〜100ミクロン長さ3mmの線状の巾を計測した結果を表1に示す。なお、粘土状のように固い場合は、現実には印刷できなかったので除外している。
なお、紋様の剥離強度は、実施例1と同じように約0.4N/mmであり高い値を示した。
同時に得られた10x30mm角の紋様を150度で熱処理した後に剥離強度を測定したところ、約0.6〜0,8N/mmと非常に高い値を示した。一般に報告されているスパッタ−法での剥離強度に遜色無く、非常に高強度であることが判明した。これは界面のニッケルの接着強度が高いことに因ると推定される。
また、ニッケルは耐酸化性があり、酸素や水分の効果的なバリアーにもなるために、銅界面の安定性が増すので、長期信頼性の向上が期待される。
事実、150℃200時間の高温処理後も0.55N/mm以上の高い値を保持しており、長期信頼性が確認された。
(比較例1)
銅鍍金された50ミクロン線状の試料をTEMで断面観察を行ったところ、サイドエッチの為に、銅と基体のポリイミド界面に腐蝕による食い込み、アンダーエッチが全般に見られ、一部には深く入っているのが見られた。フォトリソ後に強いエッチングを施したところ数ミクロンの食い込みが見られた。概念図を図3に示す。
一方、実施例1の試料では、基体のポリイミドとの界面は、端部から端部まで全く異常が無く整合していることが判明した。製造工程を考えれば当然といえる。
さらに細い線になれば、比較例の試料では、線が浮き上がり剥がれると思われる。
実施例2−3についても、同じ様にTEM観察したところ、いずれも界面の整合性は良好であることが確認された。これも製造工程からして当然といえる結果である。
