Abstract
본 발명은 반도체 레이저 다이오드 제조방법에 관한 것으로, AIGaAs계 물질을 사용하여 DC-PBH(Double Channeled-Planer Burier Heterostructure) 구조의 반도체 레이저 다이오드 제조시 메사형성후 1,2차 LPE공정에서 발생하는 AIGaAs계 물질의 산화특성을 배제시키기 위하여 메사형성을 위한 역메사를 형성시켜 LPZ의 특성인 멜트- 백(Melt-back)특성을 이용하여 역메사를 제거하여 메사를 형성시킴과 동시에 2차 1pe공정으로 p형, n형 반도체층 제 2 캡층을 연속형성함으로서 AIGaAs계 물질을 이용하여 DC-PBH 구조의 반도체 레이저 제조시 문제되는 산화를 방지하여 AIGaAs계 물질로드 CD-PBH 반도체 레이저 다이오드 제조가 가능하도록 하였다.The present invention relates to a method for fabricating a semiconductor laser diode, wherein an AIGaAs system generated in the first and second LPE processes after mesa formation in the manufacture of a double-channeled-planar burier heterostructure (DC-PBH) semiconductor laser diode using an AIGaAs-based material In order to exclude the oxidizing properties of the material, inverse mesas are formed to form mesas, and the mesas are formed by removing the mesas by using the melt-back characteristic of LPZ. By continuously forming the second cap layer of the n-type and n-type semiconductor layers, oxidation of the DC-PBH structure using the AIGaAs-based material is prevented, thereby making it possible to manufacture the AIGaAs-based material loaded CD-PBH semiconductor laser diode.
