Abstract
【解決手段】化学機械研磨の構成物は、少なくともダゾリノン類化合物もしくはトリアゾール類化合物もしくはその混合物,及びサルコシン及びその塩類化合物もしくはその混合物を含む。該抑制剤の構成物は化学機械研磨において応用し、金属層の高研磨除去率を維持すると同時に、金属エッチングの抑制の特性を兼ね備え、研磨過剰及び侵食等の研磨欠陥を減らすことができる。
【選択図】なし
Description
Dimension)が益々小さくなり、配線層数が急激に増加していることにより、RCタイム遅延(RC Time
Delay)は回路全体の操作速度に重大な影響を及ぼしている。金属連接線幅縮小によって発生したタイム遅延及び電子移動の信頼性の問題を改善するため、電気抵抗率が低く、電子移動破壊能力が高い銅配線剤を選択するようになり、アルミニウム金属に取って代わっている。しかしながら、銅金属はエッチングしにくいという特性を具えるため、別一種のダマシン方式で銅金属配線を行わなければならない。
サルコシン(sarcosine)、
sarcosine)もしくはそのリチウム塩、ナトリウム塩、カリウム塩、もしくはアミン塩等もしくはその混合物、例としてラウロイル基サルコシン・ナトリウム塩(Sodium n-Lauroyl Sarcosinate),
