Description
図1は、本発明の実施の一形態に係る化合物半導体発光素子である発光ダイオード1の構造を模式的に示す断面図である。本実施の形態では、ナノコラム2の材料としてGaNを例にとるが、これに限定されるものではなく、酸化物、窒化物、酸窒化物などを含む化合物半導体総てを対象とすることができる。また、ナノコラム2の成長は、分子線エピタキシー(MBE)装置によって行うことを前提としているが、有機金属気相成長(MOCVD)装置やハイドライド気相成長(HVPE)装置等を用いても、ナノコラム2が作成可能であることは公知である。以下、特に断らない限り、MBE装置を用いるものとする。
図6は本発明の実施の他の形態に係る化合物半導体発光素子である発光ダイオード21の構造を模式的に示す断面図であり、図7はその発光ダイオード21の具体的な製造工程を説明するための図である。この発光ダイオード21は、前述の発光ダイオード1に類似し、対応する部分には同一の参照符号を付して示し、その説明を省略する。注目すべきは、この発光ダイオード21では、壁13上にもマスク層22が形成されていることである。このマスク層22と前述のマスク層12とが同じ材質で成る場合、このマスク層22は薄く形成され、その厚さは、貫通孔22bと貫通孔12bとの個数が、所望の成長速度の差となるように選ばれればよい。また異なる材質で成る場合、前述のように吸着確率および拡散速度が変わるので、それらに所望の成長速度を勘案した厚さとなるように選ばれればよい。
