Abstract

반도체 발광 소자는 반대의 정면 및 배면을 갖는 Si 기판(1)과; 해당 Si 기판(1)의 정면상에 형성된 비정질 또는 다결정의 제1버퍼층(2)과; 해당 제1 버퍼층(2)상에, 전자와 정공의 재결합에 의해 발광하는 발광영역을 포함하도록 순차 형성된 복수의 GaN계 화합물 반도체층(3, 4, 5)을 구비한다. 이 발광소자에 있어서, Si 기판(1)은 벽개성을 갖기 때문에, 벽개에 의한 공진기 단면을 형성할 수 있다. 또한, Si 기판(1)은 도전성을 갖기 때문에, 한쌍의 전극을 발광소자의 상면 및 하면에 설치하는 구조를 실현할 수 있다. 더욱, Si 기판(1)은 염가이기 때문에, 저비용으로 발광소자를 얻을 수 있다.
