摘要 | PURPOSE:To remove leakage currents among injection electrodes by insulating and isolating a plurality of the injection electrodes. CONSTITUTION:An N-type clad layer 102, an active layer 103 and a P-type clad layer 104 are laminated on a semiconductor substrate 101, such as a GaAs substrate, an InP substrate or the like, thus constituting double-hetero structure. An N-type region 105 is formed adjacent to the layer 104, thus organizing a P-N junction. An N-type buffer layer 106 and an insulating film 107 are shaped onto the P-N junction, and P-type regions 109 as contact sections with a plurality of injection electrodes 108 are formed. Consequently, the electrodes 108 are insulated and isolated by the P-N junction shaped by the P-type clad layer 104 and the N-type region 105. Accordingly, leakage currents flowing between the injection electrodes are removed completely. |
其他摘要 | 用途:通过绝缘和隔离多个注入电极来去除注入电极之间的漏电流。组成:N型覆层102,有源层103和P型覆层104层叠在半导体衬底101,如GaAs衬底,InP衬底等,从而构成双异质结构。在层104附近形成N型区105,从而组织P-N结。在P-N结上成形N型缓冲层106和绝缘膜107,并形成作为与多个注入电极108的接触部分的P型区域109。因此,电极108通过由P型覆层104和N型区105形成的P-N结绝缘和隔离。因此,完全去除在注入电极之间流动的漏电流。 |
