Description
また、素子側面に半田付けができることにより素子の傾きが自己矯正でき、従来の下面電極構造で問題となっていた受光量の変化による出力特性のばらつきを抑えることが可能となる。更に下面、側面の電極構造を問わず、メタルマスクやリフトオフ法を用いた金属電極の形成方法により、従来の印刷工程数を半減以下にすることができ、大幅な工程数削減が可能となる。
この様に実装された素子は個々の材料の強度および密着性が大変優れており、非常に強い実装強度を示すようになる。
1.0PaのAr雰囲気下でRF出力1.0kWの放電にて1.5μmの成膜を行った。ITO、Ni両者とも円柱状の成膜治具を回転させて成膜を行い、ガラス端面の膜厚制御を行った。
