Description
蒸気放出開口が形成された上部プレート、側壁、及び底部材を含み、さらに選択された位置に熱を供給する加熱手段と、内部に収容された蒸着材料表面の高さの変化を検知する検知手段と、前記検知手段の信号に応じて前記加熱手段の作動を選択的に制御する制御手段と、を含むことを特徴とする。
<第1の実施形態>
図3aは、本発明の第1の実施形態における蒸着源の断面図である。本実施形態における蒸着源100は、上部プレート101、側壁102、及び底部材103からなる容器であり、その内部には、有機電界発光素子の固体蒸着材料(以下、“蒸着材料”と称する)20が収容されている。上部プレート101には、気化された蒸着材料の蒸気を蒸着源100から放出するための蒸気放出開口101A(以下、便宜上“開口”と称する)が形成され、上部プレート101の下面に固定された遮蔽板104は、開口101Aに対応する。
図4は、本発明の第2の実施形態における蒸着源の断面図である。本実施形態における蒸着源200の全体的な構成は、図3a及び図3cに図示された蒸着源100の構成と同一である。また、蒸着源200の上部プレート201を蒸着材料20に熱を供給するための加熱手段(ヒーター)として作用させることも、またはその上部(または下部)に別体の加熱手段を設けることもできる。以下の説明では、上部プレート201が加熱手段として作用する場合を例に挙げて説明する。
図5は、本発明の第3の実施形態における蒸着源の断面図であり、本実施形態における蒸着源300も、やはり加熱手段として作用する上部プレート301、側壁302、及び底部材303からなる。開口301Aが形成され、遮蔽板304が固定された上部プレート301の構成は、前述した第1及び第2の実施形態における蒸着源100及び200の上部プレート101及び201と同一であるため、その説明は省略する。
図7は、本発明の第4の実施形態における蒸着源と基板との関係を概略的に図示した斜視図であり、便宜上、蒸着源400の内部構成は図示しない。
