    • PURPOSE: A semiconductor lighting device and a manufacturing method thereof are provided to improve quality and luminous efficiency at a low cost by forming a ZnO and ZnO-related compound thin film on an amorphous or polycrystalline substrate. CONSTITUTION: A ZnO buffer layer(10) is formed on a substrate(1) selected from group consisting of an amorphous silicon oxide, quartz, glass and polycrystalline substrate. At this time, the stress between the ZnO buffer layer(10) and the substrate(1) is minimized by forming the ZnO buffer layer(10) at a low temperature, and then annealing at a high temperature. An N-type ZnO and ZnMgO thin film(20n,22n), and a quantum well structure layer(24) are sequentially formed on the resultant structure. At this time, the luminous efficiency of the semiconductor photo diode is improved by efficiently binding electric charge carriers and photons using the quantum well structure layer(24). After sequentially forming a P-type ZnMgO and ZnO thin film(26p,20p) on the resultant structure, A P-type electrode(5p) is formed on the P-type ZnO thin film(20p) and an N-type electrode(5n) is formed on the predetermined portion of the N-type ZnO thin film(20n).
