摘要 | PURPOSE:To enable to obtain the titled device of a low threshold value having lees current leakage by contriving the optimization of the carrier concentration of each layer. CONSTITUTION:An N-InP buffer layer 2 (with a carrier concentration of 1X 10-1X10cm), a GaInAsP active layer 3, a P-InP clad layer 4, and a P- GaInAsP ohmic contact layer 5 are successively grown on an N type InP substrate 1, thus obtaining a wafer of double hetero structure. Next, a stripe-form SiO2 film is formed, and a reverse mesa stripe is obtained by etching with the film as a mask. Then, the reverse mesa is buried, and a P-InP buried layer 6 and an N-InP buried layer 7 are formed. In this case, the carrier concentration or the layer 6 is set at 2X10-1X10cm, and that of the layer 7 at 2X 10cm-1X10cm. Thereby, the p type impurity of the layer 6 diffuses sufficiently, an excellent P-N junction being formed, and the leakage of current then reducing; accordingly sufficient low threshold oscillation is enabled. |
其他摘要 | 目的:通过设计每层载流子浓度的优化,使得能够获得具有漏电流泄漏的低阈值的标题器件。组成:N-InP缓冲层2(载流子浓度为1×10 16 -1×10 18 cm -3),GaInAsP有源层3,P-InP包层4和P- GaInAsP欧姆接触层5在N型InP衬底1上连续生长,从而获得双异质结构的晶片。接下来,形成条形SiO2膜,并通过以膜作为掩模进行蚀刻来获得反向台面条。然后,掩埋反向台面,并形成P-InP掩埋层6和N-InP掩埋层7。在这种情况下,载流子浓度或层6设定为2×10 18 -1×10 19 cm -3,层7的载流子浓度或层6设定为2×10 16 cm -3 -1×10 厘米。由此,层6的p型杂质充分扩散,形成优异的P-N结,然后电流泄漏减少;因此,启用了足够的低阈值振荡。 |
