Description
図22(a)に示すように、金属保護膜の第1の形成方法では、まず、前述した図8(a)の第2キャップ絶縁膜32及び主要配線部45aの上にタンタル(Ta)などからなる導電膜をスパッタ法で成膜することにより、膜厚が10〜50nm程度(好適には25nm程度)のめっき給電膜80を得る。なお、めっき給電膜80を無電解めっきで形成してもよい。
金属保護膜の第2の形成方法では、図24(a)に示すように、主要配線部45aは、図8(a)の主要配線部45aの最上に白金(Pt)膜44dがさらに追加されて形成されており、下から順に、TiN膜44a/Al合金膜44b/Ti/TiN膜44c/Pt膜44dが積層されて構成される。そのような積層構造の主要配線部45aを形成する際には、Pt膜44dをAr/Cl2の混合ガスを使用するスパッタ性の強いドライエッチングでエッチングした後に、通常のAl積層膜のエッチング条件に変えてその下地金属膜をエッチングする。なお、Pt膜44dはキャップ貴金属膜の一例であり、前述した金属保護膜84として機能する各種の貴金属膜を使用してもよい。
金属保護膜の第3の形成方法では、図26(a)に示すように、まず、第1の形成方法と同様に、前述した図8(a)の第2キャップ絶縁膜32及び主要配線部45aの上にめっき給電膜80を形成する。その後に、図26(b)に示すように、めっき給電膜80で被覆された主要配線部45aの幅より太い幅の開口部83xが設けられたレジストパターン83を主要配線部45aの間の領域のめっき給電膜80の上に形成する。
金属保護膜の第4の形成方法では、図29(a)に示すように、第2の形成方法と同様に、最上に白金膜44dが追加形成された主要配線部45aを形成する。次いで、図29(b)に示すように、第2の形成方法と同様に、第2キャップ絶縁膜32及び主要配線部45aの上にめっき給電膜80を形成する。さらに、図29(c)に示すように、第3の形成方法と同様に、めっき給電膜80で被覆された主要配線部45aの幅より太い幅の開口部83xが設けられたレジストパターン83を主要配線部45aの間の領域のめっき給電膜80の上に形成する。
第5の形成方法では、図31(a)に示すように、上記した第4の形成の方法の図29(d)の貴金属膜82を形成する工程において、電解めっきの処理時間を長くすることにより、レジストパターン83の開口部83xの主要配線部45aの上面側に貴金属めっき膜をさらに厚く形成する。これにより、主要配線部45aの上面側の貴金属膜82の膜厚が主要配線部45aの側方の貴金属膜82の膜厚よりも厚く設定される。
金属保護膜の第6の形成方法では、主要配線部45aの上面のみに金属保護膜が形成されて第1金属配線が構成され、第1金属配線の側面に窒化シリコンなどのエッチングされ難い絶縁物からなるサイドウォールスペーサが形成される。すなわち、図32(a)に示すように、まず、前述した図8(a)の第2キャップ絶縁膜32及び主要配線部45aの上にCVD法によりシリコン窒化膜88aを形成する。さらに、図32(b)に示すように、シリコン窒化膜88aをRIEによって全面エッチングすることにより、主要配線部45aの側面にサイドウォールスペーサ88を残す。
