Description
本願は、2021年4月9日に出願された日本国特願2021-066818号に基づき優先権を主張し、その内容をここに援用する。
図1は、本実施形態に係る露光装置の一例を示す斜視図である。露光装置1は、光学系を介して基板10に照明光を照射する装置である。露光装置1は、空間光変調器75(図2参照)で変調した光を投影光学系(後述する投影モジュール7B)に通し、この光による像を感光材料(レジスト)上に結像させて露光するものである。基板10は、表面に例えばレジストを塗布したディスプレイ用のガラス基板である。
基板ステージ4は、ベースプレート11上の不図示の案内ガイドに案内され、干渉計53やエンコーダによって基板ステージ4の位置を計測、制御し、第1方向X1や第2方向X2へ移動される。このときの基板ステージ4の移動機構としては、例えば、エアーにより基板ステージ4を浮上させるとともに磁力によって移動させるリニアモータ方式等を採用することができる。
図2に示すように、露光ユニット20は、光源ユニット6(図1参照)と、光源ユニット6の光源61と光源61からの光とを空間光変調器75(後述する)を用いて露光するための照明・投影モジュール7と、を備えている。
フォーカス調整部77は、倍率調整部76の像をスポット状に集光して焦点面である基板面10a上に投影する複数のフォーカスレンズ771を備えている。
なお、基板ステージ4における第1アライメント系5Aの配置としては、上述したように四隅であることに制限されることはない。例えば、基板10の非線形形状などのプロセス起因で発生する場合には、4箇所×4列など相当数の第1アライメント系5Aが配置される。
校正用計測系52は、各種複数のモジュールの位置の計測及び校正のために使用される。校正用計測系52は、光学定盤21上に配置された第2アライメント系5Bの校正にも用いられる。
第2アライメント系5Bは、基板ステージ4に対する不図示のホルダに吸着されている基板10の位置を計測するものである。第2アライメント系5Bは、光学定盤21を厚さ方向に貫通して設けられる第2貫通孔21cに配置されている。
第2アライメント系5Bは、第1アライメント系5Aと同様に、基板ステージ4上に基板10が載置された場合に、基板10に関する、X1方向位置,X2方向位置,回転量(θX3),X1方向の縮小/拡大倍率,X2方向の縮小/拡大倍率,直交度の6つのパラメータ(位置情報)を計測することにより算出できる。
先ず、図1に示すように、露光装置1に露光するためのレシピが投入されると、露光するためのマスクデータがマスクパターンサーバーより選択される。そして、図2に示すように、マスクデータを照明モジュール7Aの数に分割し、分割したマスクデータを生成し、各モジュールに設けられたメモリに格納する。このとき、空間光変調器75は、例えば略10kHz程度の更新レートで4Mpixelを更新するため、メモリは大容量のマスクデータを高速に格納する。モジュールは、マスクデータの準備(メモリへの送信)に合わせて、各種の露光準備を行う。すなわち、予め露光前に必要な登録された空間光変調器75のパターンをロードする。
すなわち、校正用計測系52は、照明モジュール7A及び投影モジュール7Bの配置と顕微鏡の位置を計測し、これら照明モジュール7A及び投影モジュール7Bと顕微鏡との相対位置関係を算出する。また、基板ステージ4に設けられている第1アライメント系5Aの位置は、投影モジュール7Bによって投影された空間光変調器75の露光パターンを用いて計測することで算出される。このように、第1アライメント系5A及び各モジュール7A、7Bの露光位置を算出する。
図6に示すように、基板ステージ4は、基板交換部3の交換アーム3A(図1参照)を使用して基板ステージ4上に基板10を載置する。その後、第1アライメント系5Aによって基板10のアライメントマーク12を計測する。
データ制御部では、例えば、露光中の基板ステージ4に設けられる照度計測器54や校正用計測系52で計測された照度等の光の情報を補正データとし、この補正データに基づいて照明・投影モジュール7の照度を調整することができる。このときの光の情報は、基板ステージ4のデータ補正の開始前に照明・投影モジュール7に送信される。なお、基板ステージ4でデータ補正を行っている最中に上記の光の情報を照明・投影モジュール7に送信することも可能である。
本実施形態では、1回目の露光(以下、1st露光という)はマスク露光機8で行い、2回目以降の露光(以下、2nd露光という)は空間光変調器75を用いた露光装置1で行う。露光装置1は、マスク露光機8で1st露光が行われた基板10を基板ステージ4上で支持し移動しながら、基板10に対して2nd露光となる重ね合わせ露光を行う。
マスク露光機8では、基板ステージ84とマスクステージ83とを投影光学系82に対して第1方向X1へ相対移動させるスキャン動作と、マスクステージ83に対して基板ステージ84を第2方向X2方向や第1方向X1方向に相対移動させるステップ移動と、を繰り返しながら、基板全面を露光することとなる。なお、マスクMは、基板10の1/4倍の大きさと説明したが、これに限らず、1/6倍や1/8倍の大きさも取りうる。
例えば、図9Bに示すように基板10の長辺が第2方向X2と平行となるように基板ステージ4に載置した(縦置きの)場合、図9Aに示すように基板10の短辺が第2方向X2と平行するように基板ステージ4に載置した(横置きの)場合と比較して、スキャン長、つまり基板全面を露光するために露光モジュールに対して基板ステージ84が移動する距離を短くすることができ、基板全面を露光するために必要な時間も短縮することができる。例えば、ガラス基板が6世代のガラス(1850mm×1500mm)の場合、基板ステージ84上にガラス基板が縦置きで置かれたときの露光時間は、基板ステージ84上に横置きにガラス基板が置かれたときの露光時間と比べて1500/1850となり、略23%の露光時間の短縮を図ることができる。なお、符号86は、投影モジュール7Bによる第2露光領域を示している。
露光機1は、第2方向X2に隣り合う第2露光領域86の端部どうしを継いで、基板10を露光する。この第2露光領域86を継がれて露光された基板10上の領域を、第2継ぎ領域と称する。
露光機1は、基板ステージ4を露光モジュールに対して第1方向X1へ移動させて露光する。つまり、図11Aは、1st露光時のマスク露光機8による露光時の基板ステージ84の移動方向と、2nd露光時の露光機1による露光時の基板ステージ4の移動方向とが一致(平行)して基板10が露光された結果である。図11Aでは、1st露光時の基板10の移動方向と2nd露光時の基板10の移動方向とのずれ(回転誤差)が無い露光状態となっている。ここでは、1st露光の継ぎ領域の幅に対して、2nd露光のモジュール幅を1/2としている。
図13Aに示すように、1st露光と、2nd露光とで走査方向を90°回転させることで、上述したような1st露光と、2nd露光とで走査方向を一致させ回転誤差が発生した図11Bに示すレイアウトに比べてモアレのようなムラ現象を低減することできる。また、図13Bに示すように、1st露光と、2nd露光とで走査方向を略90°回転したとしても、モアレのような現状は低減される。
次に、第1実施例として、1st露光と2nd露光との走査方向を90°回転させた場合の、露光装置1によるアライメント動作について説明する。アライメント動作とは、2nd露光をする前に行われ、1st露光の位置を、アライメントマーク12を介して計測することで、2nd露光の露光位置を1st露光の露光位置に重ねるための動作である。
なお、基板10には、向きを示すように露光領域Rに「F」が表示されている。すなわち、「F」は、基板10の長手方向を横向き(第1方向X1)にした状態で表示されている。
露光装置1は、走査方向(第2方向X2)に沿って所定の間隔をあけて複数(ここでは6個)配列されたアライメント顕微鏡56を備えている。アライメント顕微鏡56は、マスク露光機8のアライメント顕微鏡55が配置される間隔とは異なる間隔で、露光装置1内に設けられている。これは、露光機1により1st露光された基板10に対して、2nd露光も同じ露光装置1、同じ種類の露光装置1、あるいはアライメント顕微鏡56が同じ位置に設けられた別の種類の露光装置1にて露光するため、アライメント顕微鏡55とは異なる配置間隔で、アライメント顕微鏡56が設置されることがあるためである。アライメント顕微鏡56は、アライメントマーク12を観察/計測できない配置に設けられている。
図15では、露光領域Rの第2方向X2の両端のみにアライメントマーク12が1st露光で形成された例を示しているが、図14で示すアライメントマーク12と同様に、露光領域Rの第1方向X1側にもアライメントマーク12が形成された場合や、露光領域Rの境界領域にアライメントマーク12が形成された場合に、それらのアライメントマーク12をアライメント顕微鏡56が観察/計測する際に有用である。なお、基準マーク検出部は、アライメント顕微鏡56の第2方向X2の移動距離を計測できるようにしても良い。
また、露光装置1は、アライメント顕微鏡56を移動させずにアライメントマーク12を観察できるように、基板10を保持する基板ステージ4を第2方向X2へ移動させても良い。
さらに、第1実施例のように、1st露光がマスク露光機8による露光であることに限定されることはなく。1st露光が露光装置1によるものであってもよい。
計測方法の一つ(第1計測方法)として、計測したずれ量に基づいて、空間光変調器75へ送るパターンデータを補正する方法がある。具体的には、空間光変調器75ごとに、パターンデータを走査方向の+側にシフトさせる補正や-側にシフトさせる補正を行う。また、他の計測方法(第2計測方法)として、計測したずれ量に基づいて、露光モジュールごとに、投影光学系内の光学部材を移動させて、基板10上の投影領域の(露光開始)位置を、露光モジュールごとに調整する計測方法としても良い。さらに他の計測方法(第3計測方法)として、計測したずれ量に基づいて、露光モジュールごとに、空間光変調器75を移動させて、基板10上の投影領域の位置を、露光モジュールごとに調整する測定方法としても良い。なお、上述した第1計測方法、第2計測方法、および第3計測方法のうち少なくとも1つの計測方法を採用することで、露光モジュールごとに露光開始位置を調整することにより、端部がずれて露光された露光領域に対しても、重ねて露光することができる。
マスクレス露光機(露光装置1)は、次に露光する露光機のアライメント顕微鏡56が、マスクレス露光機で露光したアライメントマーク12を観察できるような位置に、アライメントマーク12を露光する。すなわち、データ生成部では、アライメント顕微鏡56の配置情報に基づいて、パターンデータを補正して、アライメント顕微鏡56で観察できる基板10上の適切な位置にアライメントマーク12を露光できるようにする。
第2実施例は、露光パターンとして、1st露光と2nd露光との走査方向を平行にしたものである。すなわち、マスク露光機8で露光した走査方向(ここでは第1方向X1)と同一方向に走査させて重ね合わせ露光を行って重ね合わせ露光部を形成する。
なお、基板10には、向きを示すように露光領域Rに「F」が表示されている。すなわち、「F」は、基板10の長手方向を横向き(第1方向X1)にした状態で表示されている。
露光装置1は、走査方向(第1方向X1)に沿って所定の間隔をあけて複数(ここでは6個)配列されたアライメント顕微鏡56を備えている。アライメント顕微鏡56は、マスク露光機8のアライメント顕微鏡55が配置される間隔と同じ間隔で露光装置1内に設けられている。
