OPTOELECTRONIC SEMICONDUCTOR CHIP AND METHOD FOR FABRICATION THEREOF

摘要

PROBLEM TO BE SOLVED: To provide an optoelectronic semiconductor chip which is particularly stable against electrostatic discharges (so-called ESD voltage pulses).SOLUTION: An optoelectronic semiconductor chip 100 comprises a first semiconductor laminate 1 which comprises a multiplicity of micro-diodes 11, and a semiconductor laminate 2 which comprises an active region 12. In the optoelectronic semiconductor chip 100, the first semiconductor laminate 1 and the second semiconductor laminate 2 are based on nitride compound semiconductor material, the first semiconductor laminate 1 is located before the second semiconductor laminate 2 in a direction of growth, and the micro-diodes 11 form an ESD protection portion for the active region 12.
