Abstract
Description
[0001]本発明は、一般に、研磨、平坦化、メッキ、およびそれらの組合せに関し、より詳細には、本発明は、研磨プロセスの終了点検出、ならびに電気化学的機械研磨および電解研磨の監視および制御に関する。
[0002]サブククォーター(0.25)ミクロン以下の多層メタライゼーションは、次世代超大規模集積回路(ULSI)にとって重要な技術の一つである。この技術の核になる多層配線は、高アスペクト比アパーチャに形成される接点、バイア、溝およびその他フィーチャを含む相互接続フィーチャの平坦化が必要である。相互接続フィーチャの信頼に足る形成は、ULSIの成功、ならびに個々の基板およびダイの回路密度および品質を向上させる不断の取り組みにとって非常に重要である。
ここで、「除去された材料の厚さ」は、電流量の関数であり、電流の積分により与えられる(以下に説明するように漏洩電流を補正してもよい)。電流信号が周期的にしかサンプリングされない場合(すなわち、終了点検出器316が、電源302のメーター318から受け取る電流値サンプルを用いる場合)、積分は合計として近似される:
電流量(t)=積分(0,t)[l(t)dt]{合計(0,t)[l(t)*(サンプリング周期)] (式2)
[0078]電流値の全時間にわたる合計を計算すると(すなわち、除去された全電荷)、「除去された材料の厚さ」は、あらかじめ決定された電荷/除去の関係を参照して決定できる。一実施形態では、電荷/除去の関係は、ルックアップテーブル等のデータ構造に格納されている。このように、ルックアップテーブルは、終了点検出器316が計算した値(すなわち、上記説明のように、式2を参照した合計により決定される全除去電荷)を、基板からの全除去材料と関連付けている。多様なプロセス条件と基板種類のそれぞれについて、別々のルックアップテーブルを備えていてもよい。例えば、パターン付き、またはパターンなしの基板について、別々のルックアップテーブルを備えてもよい。ルックアップテーブルは、更に電解質成分、除去される材料の種類等により特性付けられてもよい。このように、終了点検出器316は、多様なプロセス条件と基板種類に対して研磨サイクルの終了点を検出するよう適合可能である。
厚さ(t)=最初の厚さ-合計(0,t)[(電流(t)-漏洩(V(t)))*電流除去係数](式3)
ここで、電流除去係数は電流/除去レートの曲線(例えば、図9のプロット900)の傾き(“m”)であり、漏洩は定数(“b”)である。こうして、異なるプロセス/ウエーハに対する“m”および“b”の値はルックアップテーブルに格納でき、次いで、所与のプロセスに対して、このルックアップテーブルにアクセスして、“m”および“b”に対する適切な値を検索する。
厚さ(t)=初期厚さ-合計(0,t)[電流(t)-漏洩(V(t)))*電流除去係数/密度(厚さ(t))] (式4)
[0093]従って、係数 1/密度(厚さ(t))はブランケットウエーハに対しては1になり、その場合、式3と式4は等しくなるので、式4は式3より更に一般化した式であることが分かる。この場合も、式4を用いて厚さについて解くために必要な係数および漏洩電流は、ルックアップテーブルに格納できる。
t3…時間、t4…時間、V0…一定値
