Abstract
본 발명은 화합물 반도체 레이저 다이오드 제조방법에 관한것으로, 메사패턴높이, 활성층의 폭 및 활성층부근의 형상의 조절이 가능하도록 하기위해 상기 역메사패턴을 형성하는 웰에치 공정을 4단계 웰에치로 실시하되 첫 번째 에치는 P-InP에피텍셜층(5)이 선택적으로 에치되는 에찬트를 사용하고, 두번째 에치는 언도프된 InGaAsP활성층(4)과 n-InGaAsP웨이브 가이드층(3)의 선택적인 에찬트를 사용하고, 세번째는 에치는 n-InP층(2,5)의 선택적인 에찬트를 사용하고, 네 번째 에치는 InGaAsP층(3,4)과 InP층(2,5)에 대한 에찬트를 사용하여 역메사 패턴을 형성하는 웰에치 공정을 순차적으로 실시하는 기술이다.The present invention relates to a method for manufacturing a compound semiconductor laser diode, wherein a well etch process for forming the inverted mesa pattern in order to be able to control the height of the mesa pattern, the width of the active layer and the shape of the vicinity of the active layer is performed by four steps of well etch. The first etch uses an etchant where the P-InP epitaxial layer (5) is selectively etched, and the second etch uses an optional etch of the undoped InGaAsP active layer (4) and the n-InGaAsP waveguide layer (3). Use a chant, the third uses an optional chant for the n-InP layer (2, 5), and the fourth uses an etchant for the InGaAsP layer (3,4) and the InP layer (2,5). It is a technique for sequentially performing a well etch process for forming an inverted mesa pattern using.
