Abstract
Description
本願は、2011年2月24日に出願された米国特許仮出願61/446,150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、本実施形態に係る搬送装置1の全体構成を示す斜視図である。図2は、搬送装置1の一部の構成について、図1とは異なる視点から見たときの状態を示す斜視図である。
図1及び図2に示すように、搬送装置1は、帯状に形成され可撓性を有する基板Sを搬送する装置であり、例えば製造工場の床面FLに設けられている。搬送装置1は、基台(ペデスタル)2、第一レール3、第二レール4、基板送り出し機構5、基板巻き取り機構6、レール駆動機構7、ローラー駆動部8及び制御装置CONTを有している。
まず、供給ローラー5bと回収ローラー6bとの間に基板Sを掛け渡す動作を行う場合について説明する。
上記実施形態では、第一レール3及び第二レール4がXY平面に平行な方向へ移動する構成を例に挙げて説明したが、これに限られることは無い。例えば、第一レール3及び第二レール4がZ方向に移動可能な構成としても構わない。
図6及び図7に示すように、搬送装置1の基台2に相当する構成は、本例では、4つの支持台20A~20Dを有する構成となっている。支持台20Aには、単位レール3A及び4Aが配置されている。単位レール3Aと単位レール4Aとの間に第一処理装置PA1が接続されるようになっている。
なお、図6及び図7で示す実施形態では、第二処理装置PA2及び第三処理装置PA3において、同一の処理(第一処理装置PA1の後工程処理)が行われる例に挙げて説明するが、これに限られることは無い。例えば、第二処理装置PA2及び第三処理装置PA3では、それぞれ別々の処理が行われる構成としても構わない。
さらに、第二処理装置PA2と第三処理装置PA3を、構成上は全く同一の装置とし、装置によって処理条件(温度や湿度、処理時間、基板の送り速度、テンション量等)を異ならせて設定するような構成としても構わない。
また、第2処理装置PA2、第3処理装置PA3の後にも、支持台20Bのような構成を設けることにより、次の処理工程の装置(PA4)に、基板セットを搬入できる。
