Abstract
Description
本実施の形態にかかる成膜材料の回収方法並びに成膜材料の回収に用いられる成膜装置および回収装置について、図1の(a)~(d)乃至図8を参照して説明すれば、以下の通りである。
図5は、有機EL表示装置の概略構成を示す断面図である。
図6は、有機EL表示装置100の表示部を構成する有機EL素子120の概略構成を示す断面図である。
絶縁基板111としては、例えば、無アルカリガラスやプラスチック等を用いることができる。本実施の形態においては、板厚0.7mmの無アルカリガラスを使用した。
有機EL素子120は、低電圧直流駆動による高輝度発光が可能な発光素子であり、第1電極121、有機EL層、第2電極126が、この順に積層されている。
第1電極121は、電極材料をスパッタ法等で形成した後、フォトリソグラフィ技術およびエッチングにより、個々の画素101R・101G・101Bに対応してパターン形成されている。
図2は、本実施の形態で用いる真空蒸着装置の概略構成を示す断面図である。
ここで、真空蒸着法を用いた成膜パターンの形成方法について、主に図7および図8を用いて以下に説明する。
図8は、有機EL表示装置100の製造工程を工程順に示すフローチャートである。
図4は、蒸着工程後の真空チャンバ10内の要部の概略構成を示す断面図である。
上述したように、防着板やシャッタ等のチャンバ内構成物に付着した付着物を再利用するためには、チャンバ内構成物から付着物を脱離させる必要がある。
(1)有機溶剤を用いるので、溶剤コストがかかり、また高度な廃液設備、再処理設備が必要となる。
(2)有機溶剤が元々含有している不純物が、回収された蒸着材料に混入する。この不純物は分離が難しく、蒸着材料の昇華精製等による高純度化処理が必要となる(コスト増要因)。
(3)蒸着材料の溶解性に依存するため、回収できる蒸着材料が制限される。
(4)防着板やシャッタに対して、有機溶剤耐性を付与する必要がある。
本実施の形態について主に図9および図10の(a)~(f)に基づいて説明すれば、以下の通りである。
図9は、本実施の形態で用いられる付着物回収システムの構成の一例を示すブロック図である。
上記付着物回収システム300を用いてチャンバ内構成物70に付着した付着物22の回収・再利用を行う方法について、図10の(a)~(f)を参照して以下に説明する。
本実施の形態でも、磁石に吸着する材料としては、磁石に吸着する材質の材料であれば、特に限定されるものではない。代表的には、実施の形態1に記載したように、強磁性体部分を有する磁性材料である、強磁性体(フェロ磁性体)やフェリ磁性体が挙げられる。
本実施の形態によれば、上記したように、少なくとも蒸着材料と接触する部分に、磁石に吸着される材料からなる層が形成された削具を使用してチャンバ内構成物70から付着物22を削ぎ落とす。
なお、本実施の形態は、前記実施の形態1と組み合わせて使用することができる。すなわち、例えば、チャンバ内構成物70および削具における、少なくとも蒸着材料と接触する部分に、それぞれ、磁石に吸着される材料からなる層を設けてもよい。
本実施の形態について主に図11および図12の(a)・(b)に基づいて説明すれば、以下の通りである。
以上のように、実施の形態1~3では、真空成膜法で使用される成膜材料の回収として、真空蒸着法を用いた有機EL表示装置の製造に用いられる蒸着材料の回収を行う場合を例に挙げて説明するとともに、有機材料の回収を行う場合を例に挙げて説明した。
本発明の一態様にかかる成膜材料の回収方法は、以上のように、真空成膜装置における成膜チャンバ内に設けられた成膜治具の表面に付着した成膜材料を剥離して回収する成膜材料の回収方法であって、上記成膜治具における少なくとも上記成膜材料と接触する部分に、磁石に吸着される材料からなる層が設けられており、上記成膜治具の表面に付着した成膜材料を剥離する剥離工程と、上記剥離工程で成膜材料とともに剥離された、上記磁石に吸着される材料からなる層の破片を、磁石に吸着させて、上記成膜材料から分離して上記成膜材料を回収する分離工程とを備えている。
