Abstract
【解決手段】 光電素子の半導体層でエピタキシャル成長を行う過程において、ドーパントを高濃度ドープ(heavily−dope)することにより、この半導体層に複数個の島状体を成長させることができる。その後、エピタキシャル温度を下げることで、複数個のピンホール(pin holes)を複数個の島状体に持続的に形成する。その内、ピンホールは島状体の頂部と側面に分布し、光の光電素子内部における全反射率を大幅に下げることができ、さらには光電素子の光強度を増加させる。そして、従来の技術と比較して言えば、本発明が提示する製造工程は、低汚染、製造工程が簡単、コストが低廉、光取り出し効率がより優れている、二重スケールの出光面の有効面積が比較的大きい(平滑な出光面がほとんど存在しない)等の優位性を有している。

Description
又はパッケージ材料のエポキシ樹脂
より高い屈折係数
を有するため、従来の発光ダイオードは生じた光を完全に外に向けて発射することができず、その効率が制限される。
この方法の欠点は製造が困難なことであり、その表面形状及び形式は均一且つ非常に小さくなければならず、およそ発光ダイオードの光の単一波長の大きさでなければならない。
