Abstract
An optoelectronic semiconductor device and a manufacturing method are disclosed. The manufacturing method includes steps of: a step of providing a microsized optoelectronic semiconductor element, a step of providing a matrix substrate, a step of electrode alignment and lamination, a step of electrode coupling, a step of illumination and lift-off and a step of removal. The step of electrode coupling is to provide a first light to concentratedly illuminate at least some of the junctions between the first electrodes and the third electrodes or concentratedly illuminate at least some of the junctions between the second electrodes and the fourth electrodes. The step of illumination and lift-off is to provide a second light to concentratedly illuminate at least some of the interfaces between the microsized optoelectronic semiconductor elements and the epitaxial substrate to peel off the microsized optoelectronic semiconductor elements from the epitaxial substrate.
