Abstract
【解決手段】実施形態の一態様に係る接合システムは、基板搬送装置と、表面改質装置と、ロードロック室と、表面親水化装置と、接合装置とを備える。基板搬送装置は、第1基板および第2基板を常圧雰囲気にて搬送する。表面改質装置は、第1基板および第2基板の接合される表面を減圧雰囲気にて改質する。ロードロック室は、室内において基板搬送装置と表面改質装置との間での第1基板および第2基板の受け渡しが行われるとともに、室内の雰囲気を大気雰囲気と減圧雰囲気との間で切り替え可能とされる。表面親水化装置は、改質された第1基板および第2基板の表面を親水化する。接合装置は、親水化された第1基板と第2基板とを分子間力により接合する。

Description
<1.接合システムの構成>
まず、第1の実施形態に係る接合システムの構成について、図1および図2を参照して説明する。図1は、第1の実施形態に係る接合システムの構成を示す模式平面図であり、図2は、同模式側面図である。また、図3は、第1基板および第2基板の模式側面図である。なお、以下においては、位置関係を明確にするために、互いに直交するX軸方向、Y軸方向およびZ軸方向を規定し、Z軸正方向を鉛直上向き方向とする。また、図1〜3を含む各図面では、説明に必要な構成要素のみを示しており、一般的な構成要素についての記載を省略する場合がある。
次に、接合装置41の構成について図8〜図13を参照して説明する。図8は、接合装置41の構成を示す模式平面図であり、図9は、同模式側面図である。また、図10は、接合装置41の内部構成を示す模式側面図である。
次に、上述のように構成された接合装置41における上ウェハW1および下ウェハW2の位置調節、および、上ウェハW1と下ウェハW2との接合動作について、具体的に説明する。図14A〜図14Hは、接合装置41の動作説明図である。
次に、以上のように構成された接合システム1の具体的な動作について図15を参照して説明する。図15は、接合システム1が実行する処理の処理手順の一部を示すフローチャートである。なお、図15に示す各種の処理は、制御装置100による制御に基づいて実行される。また、図15に示す処理は、接合システム1の接合装置41において通常の接合処理が行われる「通常モード」での処理である。
次に、テストモードについて説明する。本実施形態に係る接合システム1には、上記した「通常モード」の他に、接合システム1内での上ウェハW1や下ウェハW2の搬送状態を確認するための「テストモード」がある。
次いで、変形例に係る接合システム1について説明する。上記した第1の実施形態においては、搬送装置61によって保持される上ウェハW1および下ウェハW2の位置検出を行う場合、上下ウェハW1,W2がそれぞれ1枚で保持されるタイミングで位置検出を行うようにしていた。
次いで、第2の実施形態に係る接合システム1について説明する。第2の実施形態に係る接合システム1は、ロードロック室31、搬送室32、表面改質装置33、表面親水化装置34、接合装置41、基板温調装置42および排気口43をそれぞれ複数(ここでは2つ)備えるようにした。
次いで、第3の実施形態に係る接合システム1について説明する。図20は、第3の実施形態に係る接合システム1の構成を示す模式平面図である。
