Abstract: PURPOSE:To obtain an LED high in fiber coupling output and able to be manufactured with high yield, by constructing a semiconductor light-emitting diode having a double-hetero layer-built structure including an active layer such that it has a linear groove extending in a particular direction with a circular-mesa- type light-emitting section formed within the groove. CONSTITUTION:On an N-type InP substrate 11, there are deposited an N-type InP layer 12, an N-type InGaAsP active layer 13, a P-type InP layer 14 and a P-type InGaAsP contact layer 15 sequentially by the liquid-phase epitaxy. Then, a linear groove 17 extending in the direction <110> is formed by chemical etching while a circular mesa 16 with a diameter of 25mum is also formed within the groove. An insulating film 18 of silicon nitride is deposited on the surface of the groove 17 and P-type InGaAsP contact layer 15. The insulating film on the top surface on the circular mesa 16 is removed by a selective etching process using photoresist. A TiPt film is formed to provide a P-type electrode 19 on that surface from which the insulating film has been removed. Then an AuGeNi film is formed to provide an N-type electrode 21. In this manner, it is possible to decrease short-circuit due to current-voltage characteristics.
