Description
ジークフリート・シラー、ウルリッヒ・ハイジッヒ共著、日本真空技術株式会社訳「真空蒸着」株式会社アグネ出版、1979年8月1日
(作用)
蒸着材の融点よりも低い温度でMgを昇華させるため、蒸着材が溶融せず、蒸着材が加熱装置の放出面からこぼれ落ちることがない。このため、加熱装置の放出面をあらゆる方向に位置させることができる。
〈実施形態1〉
図1は、本発明の実施形態1に係わるMg蒸着方法を示す概念正面図である。
ここで、P(Pa)は温度T(K)における飽和蒸気圧で、Mは蒸発分子の分子量、Tは蒸発面の絶対温度、αは蒸発係数である。この蒸発係数αは、実際の蒸発面からの蒸発速度と、理想状態にある蒸発面からの蒸発速度との比であり、極めて清浄な蒸発面ではα≒1であり、多くの金属ではα=1として扱っている。
〈実施形態2〉
本実施形態では、蒸着材3としてAZ31材(基板2と同じ材質)を用いており、その形状は、断面が1mm×2mmで、長さが90mmの角棒である。また、本実施形態では、加熱装置4の温度を約850Kに保持している点で、上記実施形態1と異なる。
〈実施形態3〉
本実施形態では、加熱装置4がFe−28%Cr−15%Niの耐熱綱製である(実施形態1と同様にパイプ状)点のみが、実施形態1と相違する。
〈実施形態4〉
本実施形態では、Fe−28%Cr−15%Niの耐熱綱製の加熱装置4(実施形態1と同様にパイプ状)に、幅4mmのスリットを形成し気化Mgの放出孔とした。さらに、真空槽1内の左右、上部に位置する3つの加熱装置4には、スリットから蒸着材3(実施形態1と同様にリボン状)がはみ出ないように、スリットと交差するように4カ所にタンタル線を巻き付けた。本実施形態は、これらの点で実施形態1と相違する。
〈実施形態5〉
本実施形態では、加熱装置4をヒーター6によって加熱する点で、実施形態1と相違する。すなわち、ヒーター6は赤外線加熱ヒーターで、このヒーター6を加熱装置4の背面に配置し、加熱装置4を加熱した。
