図1~図5は、基板Wの一部(特にビアホール11を有する部分)の断面を例示する図であり、基板液処理方法の流れの一例を示す。
図6は、加熱処理を含む基板液処理方法の一例を示すフローチャートである。
SAM13及び分子間結合剤15の各々の具体的な組成は、基本的には限定されないが、様々な要求特性を総合的に勘案して選定される。特に本実施形態のSAM13の組成は、拡散バリア層としての機能、絶縁膜21及び分子間結合剤15に対する良好な結合性、及びキャップ層14の露出確保を考慮して決められる。一方、分子間結合剤15の組成は、SAM13及びめっき金属に対する良好な結合性、及び、キャップ層14の露出確保を考慮して決められる。
次に、上述の基板液処理方法を行う基板液処理装置の一例について説明する。
上述の装置(図11~図16参照)では、SAM13の溶液を付与する処理、分子間結合剤15の溶液を付与する処理、無電解めっき液20を付与する処理、基板Wの加熱処理、及び基板Wから溶液を除去する処理が、お互いに別の処理ユニット30で行われる。しかしながら、これらの処理の一部又は全部は、共通の処理ユニット30(すなわち同一の処理チャンバー内)で行われてもよい。
