Description
背景技術
半導体製造処理はしばしば開口内での電気的相互接続部の形成を含む。開口の所望のアスペクト比は、例えば、キャパシタンス又はインダクタンスの損失を補償することを含めて、様々な理由で増大している。アスペクト比の増大とともに、従来の処理により開口を共形的に(コンフォーマルに)充填することがますます困難になる。図1及び図2は、例示的な従来技術の処理と、開口内に電気的相互接続部を形成しようとする間に生じ得る問題を示す。
一つの態様においては、本発明は、電気的接続部を形成する半導体処理方法を含む。まず、半導体基板が提供される。基板は、無電解メッキに適した表面と、表面上の層と、この層によって支持されるノードとを有する。開口は層を通って上記適した表面まで形成される。開口の周辺部はノードの導電性部分を含む。導電性材料が開口内に無電解メッキされるが、無電解メッキは上記適した表面で開始される。無電解メッキ材料はノードへの電気的接続部を形成する。
好ましい実施の形態の詳細な説明
本発明は、無電解メッキを使用して開口内に電気的相互接続部を形成する方法を含む。無電解メッキの利点は、開口の底部から最上部まで開口を充填するようにでき、したがって、充填処理期間に開口の最上部を閉じるという従来技術の問題無しに、高アスペクト比の開口を充填することができることである。
キャパシタ構造58は電気絶縁層56によって支持される。キャパシタ構造58は、第1のキャパシタ電極60、第2のキャパシタ電極62、及び、キャパシタ電極60、62間の少なくとも1つの誘電材料64を備える。キャパシタ電極60、62は、例えば、金属、金属組成、及び/又は導電性にドープされたシリコンを含む任意の適宜の導電性材料を含むことができる。特定の態様では、電極60はキャパシタの記憶ノードに対応し、電極62はキャパシタのプレート電極に対応する。キャパシタ電極の一方又は両方は、或る態様では、導電性にドープされたシリコン(導電性にドープされた多結晶シリコンなど)及び/又は、例えば、TiN、WN、及びWSiのうちの1つ又は複数などの金属組成を含むが、ここに挙げられた組成は、組成における元素の特定の化学量論に関してではなくそこに含まれる元素に関して示されている。
キャパシタ記憶ノード60がトランジスタ・デバイス69に電気的に接続される様子が示される。当業者に知られているように、トランジスタ・デバイス69は、一般に、ゲート(図示せず)と1対のソース/ドレイン領域(図示せず)を備える。記憶ノード60はソース/ドレイン領域の一方に接続され、ソース/ドレイン領域の他方はビット線(又はディジット線)(図示せず)に接続される。したがって、トランジスタ・ゲートは記憶ノード60をビット線にゲート制御可能に接続する。こうして、キャパシタ構造58はメモリ・セルのメモリ記憶ユニットとして利用することができる。具体的には、トランジスタ構造とキャパシタの組合せは、ダイナミック・ランダム・アクセス・メモリ(DRAM)デバイスの一般的なユニット・セルである。当業者に知られているように、複数のキャパシタ及びトランジスタをDRAMアレイに組み込むことができる。
図7を参照すると、開口120、122がそれぞれ層56を通って上部導電性表面55、105まで形成される。以下の説明では開口120は第1の開口と呼ばれ、開口122は第2の開口と呼ばれる。開口120は前に説明した開口70(図4)と同じである。開口122は前に説明した開口72(図4)と同じ位置にあるが、開口72と異なり、キャパシタ誘電体64及びキャパシタ・プレート電極62を完全に通って延びている。したがって、開口122は電極62の導電性部分を含む周辺部を有する。開口122の周辺部のそのような導電性部分は、図7に124として表示される。開口120は第1の絶縁性材料を通って形成されると言われ、開口122は第2の絶縁性材料を通って形成されると言われる。本発明の図示された態様では、第1の絶縁性材料及び第2の絶縁性材料は共通の層によって構成されるが、上で説明したように、第1の絶縁性材料及び第2の絶縁性材料は本発明の他の態様では互いに異なってもよい。
