Description
ここで、バリアメタル膜はバリア性が高いと同時に応力も高い膜であるがゆえに、その下層のブリーダー抵抗であるポリシリコン膜に応力による抵抗値変動をも及ぼす。そのため、ブリーダー抵抗の上層にバリアメタル膜を配置すると、ブリーダー抵抗の分圧比が不正確となる虞があった。
一方、トランジスタ回路の配線として用いられる金属膜については、配線の信頼性の見地から、反射防止膜/配線膜/バリアメタル膜よりなる既存構造からの変更をしない。
本実施例は、図1に示すように、ブリーダー抵抗回路においては、ブリーダー抵抗102の上層に層間絶縁膜107を配置し、その上層に金属膜として、反射防止膜(図示省略)、配線膜103を配置するものである。
なお、トランジスタ回路、ブリーダー抵抗回路の双方において、金属膜の最上層となる反射防止膜は必要性に応じて省略することができる。また、トランジスタ回路としては、ブリーダー抵抗を使用する電源系IC(例えば、ボルテージディテクタ等)とすることができる。
一方、トランジスタ回路の配線として用いられる金属膜についてはバリアメタル膜104が存在するので、配線の信頼性を損なう事もない。
一方、トランジスタ回路においてはトランジスタ構造の上層に層間絶縁膜107を配置し、その上層に金属膜として、反射防止膜(図示省略)/配線膜103/バリアメタル膜104を配置したものである。
尚、その他の構成については、前述した実施例1と同様であり、同一箇所には同一符号を付して、重複する説明を省略する。
そして、図8に示すように、バリアメタル膜104の一部除去により露出した層間絶縁膜107及び除去されなかったバリアメタル膜104の上に、Al,Al−Cu等の配線層103をスパッタ等で堆積させ、図9に示すように、配線を形成するためのフォトレジスト109を塗布・露光・現像してパターニングする。
尚、この後、図示は省略するが、表面保護のため、パッシベーション膜(酸化膜主体の絶縁膜)を形成する。
