図1に示すように、第1実施形態の露光装置PEは、露光処理部1として、マスクM(M1、M2)を保持するマスクステージ10と、ガラス基板(被露光材)W(W1,W2)を保持する基板ステージ20と、パターン露光用の光を照射する照明光学系30(30a,30b)と、を備えている。
なお、x軸、y軸とは、水平面内で直交する2軸であり、θ方向とは、水平面の任意の位置で鉛直方向に延びるz軸回りの回転方向を表す。
また、制御部60は、第1及び第2の搬入装置31,32と、第1及び第2の搬出装置33,34と、による露光装置PEに対する基板W1,W2の搬入及び搬出が同期して行われるように、第1及び第2の搬入装置31,32と、第1及び第2の搬出装置33,34と、第1及び第2のベルトコンベア16,17を制御する。さらに、制御部60は、第1搬入装置31により基板保持部21の1つに載置した基板W1と、第2搬入装置32により基板保持部21の1つに載置した基板W2と、に対して、マスクMとのギャップ調整と、露光光を照射することを、同期して制御する。また、制御部は、第1の基板W1及び第2の基板W2に対して、基板W1,W2の所定の基準位置とのズレ量を算出や、ギャップの測定も、同期して制御することができる。
さらに、例えば、露光処理部1の各位置での動作は、回転テーブル22の回転停止を基準として同期して制御させてもよい。
その後、露光装置PEに配設したギャップセンサ13aにより、第1及び第2の基板W1、W2の板厚を検出する。その検出した板厚hを制御部60の記憶部に記憶する。それから、回転テーブル22を時計周りに45°移動する。(図4)
なお、基板W1,W2のアライメント調整やギャップ調整は、基板保持部21を駆動する図示しない基板駆動機構によって行われてもよいし、あるいは、マスク保持枠12を駆動する図示しないマスク駆動機構によって行われてもよいし、あるいは、両方で行ってもよい。ただし、後述する露光位置22C,22F以外でのアライメント調整やギャップ調整の場合には、基板保持部21を駆動する基板駆動機構によって行われる。
従って、第1及び第2のベルトコンベア16,17は、回転テーブル22のインデックス回転に同期して、所定の距離ずつ移動し、基板W1,W2を搬入した後のコンベア16,17の位置に、露光された基板W1、W2が載置される。
上記実施形態では、回転テーブル22には、基板Wの厚さと、基板保持部21の所定の基準位置に対する基板Wのズレ量とを検出する、複数の基板情報取得位置22B,22Fが、搬入位置22A,22Eと露光位置22C,22Gとの間にそれぞれ設けられていたが、この変形例では、基板W1,W2のアライメント調整やギャップ調整を行う調整位置22I,22Jが、搬入位置22A´,22E´と露光位置22C´,22G´との間にそれぞれ設けられている。
この変形例では、第1変形例と同様に、搬入位置22A´,22E´にて、基板Wの厚さと、基板保持部21の所定の基準位置に対する基板Wのズレ量とが測定され、調整位置22I,22Jにて、基板W1,W2のアライメント調整と基板W1,W2とマスクMA1,MA2間のギャップ調整とが行われる。その後、回転テーブル22の回転を停止せずに、マスクMA1,MA2によるスキャン露光が行われる。
この変形例では、単一の照明光学系30によって、2か所の露光位置22C,22Gに位置する基板保持部22の基板W1,W2を露光する。したがって、2つの照明光学系30A,30Bの光源を同時に照射する同期制御が少なくなるため、タクトタイムを短縮することができる。なお、光源が長くなると、光源の照度にばらつきが生じるため、マスクM1,M2に設けられたパターンのサイズが、基板W1,W2に転写されるパターンサイズと異なり、露光精度が悪くなる。そこで、この変形例では、シャッター15によって露光光を2つに分けている。
図10(a)は、本発明の第2実施形態に係る露光装置の露光処理部を説明するための正面図であり、(b)は、露光装置の概略構成図である。なお、第1実施形態と同等部分については、同一符号を付して説明を省略あるいは簡略化する。
図11(a)は、本発明の第3実施形態に係る露光装置の露光処理部を説明するための正面図であり、(b)は、露光装置の概略構成図である。なお、第1実施形態と同等部分については、同一符号を付して説明を省略あるいは簡略化する。
まず、上流コンベア40より複数の基板W1~W3を並列に同時搬送(並列処理)させ、搬入側ターンロボット42によって、基板を搬入コンベア35へ直列に並び替える。
この変形例では、搬入コンベア35Aでは、可動テーブル37がY方向に複数の基板W1~W4を配置可能に構成されており、リニアガイドや不図示のアクチュエータを備えたY方向駆動機構38によってそれぞれ、可動テーブル37をY方向に移動可能に構成されている。また、搬出コンベア36Aでも、可動テーブル37がY方向に複数の基板W1~W4を配置可能に構成されており、リニアガイドや不図示のアクチュエータを備えたY方向駆動機構38によってそれぞれ、可動テーブル37をY方向に移動可能に構成されている。
例えば、本実施形態や変形例は、光源、コンベア、マスク、搬入、搬出装置の個数を適宜増やすことができる。
