Abstract

본 발명은 광통신용 반도체 레이저 다이오드 제조방법에 관한 것으로, InGaAsP계의 식각정지층을 InP 클래드층 상부에 형성하고, 마스크를 이용한 건식 식각 습식 식각을 통하여 종래와 다른 모양의 메사 프로파일을 형성하고, 그로인하여 성장 속도가 다른 두면을 갖는 메사면을 노출시키고, 전류제한등 성장시 각면에서 ({111},{100})에서의 성장 속도 제어와 {111}면과 {100}면의 경계에서 성장을 제어하여 전류제한층의 성장을 제어할 수가 있다.The present invention relates to a method for manufacturing a semiconductor laser diode for optical communication, wherein an InGaAsP-based etch stop layer is formed on an InP clad layer, and a mesa profile having a different shape from a conventional shape is formed through dry etching wet etching using a mask. To expose the mesa surface with two different growth rates, and control growth rate at ({111}, {100}) and growth at the boundary between {111} plane and {100} plane at each side during growth such as current limit. By controlling the growth of the current limiting layer can be controlled.
