Abstract
【解決手段】薄膜堆積用分子線源は、るつぼ31、41の中の薄膜素子材料a、bを加熱するためのヒータ32、42と、基板51の成膜面へ向けて前記るつぼ31、41で発生した薄膜素子材料a、bの分子を放出する量を調節するバルブ33、43を備える。さらに、前記成膜面に向けて放出される分子線量を検知する膜厚計16、26で検知された分子線量情報を帰還して、サーボモータ36、46によりバルブ33、43の開度を調節する制御手段と、前記ヒータ32、42の加熱のための電力を供給する加熱電源と、前記分子線量情報とバルブ開度情報とから前記加熱電源の投入電力を調整する制御手段とを備える。
【選択図】図1
Description
下記の特許文献2には、分子線量の調整手段として2つの制御手段が挙げられている。一つは、前述したようなバルブによる分子線量の調整手段である。他の一つは、るつぼをヒータで加熱する温度による制御手段である。しかし、後者のるつぼをヒータで加熱する温度による制御手段は、間接的で時間遅延があるため、精密な分子線量の調整には適さない。
以下、本発明を実施するための実施の形態について、図面を参照しながら詳細に説明する。
この分子線源セル1の材料収納部3は、SUS等の金属の高熱伝導材料からなる円筒容器状のるつぼ31を有し、このるつぼ31の中に薄膜素子材料aが収納されている。
すなわち、この第二の分子線源セル2の材料収納部4は、SUS等の金属の高熱伝導材料からなる円筒容器状のるつぼ41を有し、このるつぼ41の中に薄膜素子材料bが収納されている。こ
この図5に示すように、膜厚計16、26からは分子線源セル1、2から放出される分子線量に応じた信号が発生し、この信号は処理器17、27から分子線コントローラ18、28を経てバルブコントローラ37、47とヒータコントローラ38、48に送られる。
サーボモータ36、46のバルブ33、43の開度の指示値が定められた上限値と下限値の間にある場合は、ヒータコントローラ38、48への指示のへの指示の変更は行われない。
