摘要 | An n-InP buffer layer 102, an InGaAsP active layer 103, a p-InP cladding layer 104 and a p-InGaAsP surface protective layer 105 are successively epitaxially grown on an n-InP substrate 101 having a (100) plane as a main plane. An etching mask 106, an insulating film, is formed in a stripe in the direction by photolithography and dry etching. Using a solution comprising a mixture of hydrochloric acid, oxygenated water and acetic acid, the n-InP buffer layer 102 is etched to a depth lower than the p-InP cladding layer 103, to form a mesa stripe 107. Next, the insulating film 106 is removed and the p-InGaAsP surface protective layer 105 is removed using a solution comprising a mixture of sulfuric acid and oxygenated water. Thereafter, InP current blocking layers 108 and 109 are selectively formed at the regions other than the mesa stripe 107 by the liquid-phase epitaxial growth. Thus, a buried heterostructure semiconductor laser is fabricated, having good laser characteristics and a high reliability. |
其他摘要 | n-InP缓冲层102,InGaAsP有源层103,p-InP包层104和p-InGaAsP表面保护层105在具有(100)面作为主要的n-InP衬底101上连续外延生长平面。通过光刻和干法蚀刻在方向上以条纹形成蚀刻掩模106,即绝缘膜。使用包含盐酸,氧化水和乙酸的混合物的溶液,将n-InP缓冲层102蚀刻至低于p-InP包层103的深度,以形成台面条107.接下来,绝缘膜除去106并使用包含硫酸和含氧水的混合物的溶液除去p-InGaAsP表面保护层105。此后,通过液相外延生长在除台面条107之外的区域选择性地形成InP电流阻挡层108和109。因此,制造了掩埋异质结半导体激光器,其具有良好的激光特性和高可靠性。 |
