Description
本発明は、全般的にはケミカルメカニカルポリッシングのための研磨パッドの分野に関する。特に、本発明は、メモリ及び論理集積回路の基板工程(front end of line)(FEOL)又は配線工程(back end of line)(BEOL)処理を含む、磁性、光学及び半導体基板のケミカルメカニカルポリッシングのために有用な研磨構造を有するケミカルメカニカルポリッシングパッドに関する。
集積回路及び他の電子デバイスの製造において、導電性材料、半導体材料及び絶縁材料の複数の層が半導体ウェーハの表面上に堆積されるか、又はそこから部分的又は選択的に除去される。導電性材料、半導体材料、及び絶縁材料の薄層は、多くの堆積手法を使用して堆積されてもよい。最新のウェーハ加工における一般的な堆積手法は、とりわけ、スパッタリングとしても知られている物理気相成長法(PVD)、化学気相成長法(CVD)、プラズマ化学気相成長法(PECVD)、及び電気化学的めっき法(ECP)を含む。一般的な除去手法は、とりわけ、ウェット及びドライ等方性及び異方性エッチングを含む。
本明細書において開示される方法及び研磨パッドは、確かな利点を提供し得る。具体的には、研磨パッドの設計は、比較的高い表面研磨表面積(これは研磨されるべき表面に接触するパッドの部分であるので接触面積とも称される)を提供し得、一方、空隙は、典型的に使用される研磨流体の良好な管理/運搬を可能にする。この流体管理特徴は、温度を制御する、例えば研磨中、摩擦加熱に起因する温度の上昇を減らすか、又は制限するのに、役立ち得る。より低い研磨温度は、研磨パッドの機械的特性を維持するのに役立ち得、かつパッド又は研磨されている基板において不可逆的な熱誘導化学反応を回避するのに役立ち得る。パッドにおける化学反応は、研磨中の欠陥発生の可能性を増すことがある。
Claims (3)
- 上面を有するベースパッド及び平面を画定する前記上面、
各々が上部研磨表面及び底面を有する複数の研磨要素を含む、ケミカルメカニカルポリッシング用の研磨パッドであって、
