Abstract: PURPOSE:To prevent exposure to an etchant and the out side air of the interface of a P-N junction, and to improve the performance and re liability of a semiconductor element by providing a process in which an outermost surface layer in a crystal growth process before forming a trench is formed as a junction protective layer having the same conductivity type as a semiconductor layer shaped onto the outermost surface layer in a crystal growth process after forming the trench. CONSTITUTION:Current blocking layers 2, 3 are grown on a substrate 1 in succession, and an impurity is diffused to the current blocking layer 3, thus shaping a junction protective layer 7. A trench S is formed through etching, and an optical confinement layer 4, a light-emitting section 5 and an optical confinement layer 6 are grown in succession through crystal growth, thus shaping a semiconductor light-emitting device. Since the same second conductivity type optical confinement layer 6 is grown on the junction protective layer 7 in the semiconductor light-emitting device acquired in such a manufacturing process, a boundary section between both layers 7 and 6 is formed in the same conductivity type boundary surface. Accordingly, voltage is hardly applied to the boundary surface, deterioration does not progress even when large currents are caused to flow, and the current blocking capacitance of a P-N junction is not affected even when the de vice is deteriorated.
