Abstract
【解決手段】 本発明では、リフレクタ基板34は両面に導電箔35、36が設けられ、貫通孔31は導電箔35、36を貫通して形成され、貫通孔31の内壁の傾斜面32に導電箔を電極として導電メッキ膜37が形成され、導電箔35および導電メッキ膜上に反射メッキ膜33を形成することにより、ガラスエポキシ基板に機械的にリフレクタを形成することを特徴とする。
【選択図】 図4
Description
また、他の光半導体装置についてもリフレクタとして働くケースがポリカーボネイトに酸化チタンを含ませた光反射率の高い白色系の樹脂の成型により形成されている。(特許文献2、図3参照)
特に、コストを低減するためにリフレクタを樹脂成型で作る場合が多く、その場合には以下に述べる種々の問題点が発生する。
このために樹脂に比べてコストの高いガラスエポキシ基板を用いても金型を用いないこととともにコストアップを抑えられる。
