Abstract
Description
本出願は、2007年8月3日に出願された、米国特許出願第11/833,386号の出願日の利益を主張する。
本発明の実施形態は、概して、集積回路製造技術に関する。より詳細には、本発明の実施形態は、縮小されたピッチあるいは「緊密な」ピッチのコンタクトを組み込む半導体構造体の製造に関し、それらの縮小されたピッチあるいは「緊密な」ピッチのコンタクトは、活性領域(active area)のフィーチャ、ならびに任意的にはそれらの上方の関連する導電線と位置合わせ(alignment)される。
通して半導体基板110をイオンでドープすることによって、半導体基板110の表面中に活性フィーチャ112が形成され得る。
本発明の実施形態では、半導体構造体は、緊密なピッチの導電線ならびに活性領域のフィーチャと位置合わせされた緊密なピッチのコンタクトを含む。そのラインおよびコンタクトは、それらが一体的に形成される単一の構造体を含むように、同じ材料から同時に形成され得る。重ね合わされたマスク構造体の組み合わせを使用して、導電線用のトレンチならびにコンタクトホールを同時に製作することにより、緊密なピッチならびにそれらの間の位置合わせが可能となり得る。製造の行為、ひいては時間と材料が節約される。さらに、コンタクトホールが導電線用のトレンチと共に同時に形成されるので、ラインとそれに関連するコンタクトとの位置ずれ(misalignment)についての何らかの可能性は、少なくとも1つの方向に最小限度に抑えられる。本明細書では、用語「半導体構造体」は、ウエハおよびその他のバルク半導体基板、部分的なウエハ、ダイ群、ならびにシンギュレーションされたダイを含む。そのような半導体構造体は、パッケージ化された集積回路およびパッケージ化されていない集積回路の両方の他に、製造過程の半導体構造体をも含む。
