Abstract
【選択図】図7
Description
もよく、これにより、上記の下方層にプレースホルダ(placeholders)又はマンドレル(mandrels)が形成される。その後、フォトレジストラインが剥離され、マンドレルが異方的にエッチされることが可能で、これにより、隣り合ったマンドレル間の距離が増大される。好ましくは、隣り合ったマンドレル間の距離はFから3F/2までに増大される。或いは、異方性の“シュリンク(shrink)”又は“トリム(trim)”エッチングであれば、レジストのレベルで行なわれることも可能であろう。次に、スペーサ材料のコンフォーマル層(conformal layer)がマンドレル上に堆積されてもよい。この材料層は、マンドレルの水平面及び垂直面の両方を覆う。よって、方向性のスペーサエッチにおいて、上記水平面からスペーサ材料を優先的にエッチングすることにより、スペーサ、すなわち他の材料の側壁から延びている材料が、マンドレルの側壁に形成される。その後、残りのマンドレルが、パターン化用のマスクとして共に作用するスペーサの背後のみを残して、選択的に除去される。従って、特定のピッチ2Fが、最初には1つの構成及び1つのスペースを規定するパターンを含んでいた場合、それと同じ幅が、今はスペーサによって規定された2つの構成及び2つのスペースを含んでいる。その結果、特定のフォトリソグラフィ技術で達成可能な最小の構成サイズが、有効に減少される。このピッチ二重化の方法は、これが繰り返し行なわれることで構成のサイズが更に減少させられ、これは図3〜9を参照して以下で一層詳細に議論される。
合構造、又は化学結合構造での各種の材料からなっていてもよい。
いては、2本のワードラインの両方がソース及びドレイン間を延びることで、トランジスタの冗長制御を提供するようにしてもよい。
て、ディジットライン及びワードラインの組み合わせを選択することで、データを書き込むべき又は読み出すべき蓄積キャパシタ24が一意に識別可能となる。
r)40が上に形成された半導体基板11を示しており、上記臨時層は、好ましい一実施形態においては酸化物からなっている。次に、窒化シリコンのようなハードマスク層42が、基板11及び臨時層40の上に堆積される。このハードマスク層42は、とりわけ、スパッタリング、化学気相蒸着(CVD)、又は低温蒸着のような何らかの周知の堆積プロセスによって形成可能である。好ましい実施形態においてはハードマスク層42は窒化シリコンからなるが、それは例えば酸化シリコン又は以下に述べる選択性エッチステップに適した他の材料で形成されてもよい、と理解されるべきである。
術のみを用いて可能な最小ピッチよりも狭い幅で離間されたトレンチ50の形態をなしている。好ましくは、トレンチ50は、その上部で約25nmと75nmの間の幅を有している。勿論、当業者であれば、図6に示された段階へと到達するのに、ピッチ多重化のための他の多くの技術が使用されてもよい、と認識するであろう。そのような多くの技術は、一般にスペーサプロセスを含んでおり、このような物理蒸着により、フォトリソグラフィ技術単独でよりも小さなピッチを達成可能である。トレンチ50はまた、典型的には、1:1よりも大きなアスペクト比を有しており、好ましくは2:1よりも大きい。深さが増したことで、利用可能な容積が最大化され、よって、適当な材料で充填する上での困難性を犠牲にして、ワードラインの導電率が最大化される。
完全反応はまた、珪化物がトレンチ50の底まで形成されるのを保証する。図示された溝形アクセスデバイス(RAD)においては、その経路がゲートの底を横切って延びるだけでなく、ゲートの側壁にも沿って延びている。よって、珪化が不完全であれば、結果的に、RAD経路の長さに沿って異なる仕事関数が得られてしまう。更に、完全珪化により、1つのウェハを横切ってアレイからアレイへと、かつ、ウェハからウェハへと、アレイを横切る同様なゲート仕事関数が保証される。しかし、図示されたトレンチ50の窮屈な境界線内において、導電材料56を形成するための単一材料を用いて完全珪化を達成するのは困難であることがわかっている。例えばニッケルかコバルトのどちらかが、高アスペクト比のトレンチ50内に空隙を形成する傾向にある。他の金属は、溝形アクセスデバイスのための完全珪化に同様な困難性を示している。当業者であれば、完全珪化は、コンタクト開口又はビア、キャパシタ用のスタック形コンテナ形状、キャパシタトレンチ等のような他のタイプの溝内の材料にとって冒険になり得る、ということを認識するであろう。
化された溝形のNixCoySizゲート材料を示す顕微鏡写真である。図10A及び10Bは、一対のトレンチの幅を横切る断面を、2つの異なる倍率で示している。図11A及び11Bは、それらトレンチのうちの一方の長さに沿った断面を、2つの異なる倍率で示している。これらのトレンチは、そのアスペクト比が約3:1となるよう、その上部で約50nmの幅を有すると共に、約150nmの深さを有している。滑らかで均一な構成が観察されており、これはトレンチの少なくとも下方部分を空隙なしに充填している。図11〜12の例においては、ポリシリコン52(図7)が堆積された後に、このポリシリコンがゲート誘電体上面54までエッチされ、これにより、トレンチ内のシリコンが溝形に形成されることなく分離される。
ン60の上面上には重要な更なる酸化物は成長しない。
料が使用可能であることを認識するであろう。
