Abstract

See full text

Disclosed is a die-bonding method which provides a target substrate having a circuit structure with multiple electrical contacts and multiple semiconductor elements each semiconductor element having a pair of electrodes, arranges the multiple semiconductor elements on the target substrate with the pair of electrodes of each semiconductor element aligned with two corresponding electrical contacts of the target substrate, and applies at least one energy beam to join and electrically connect the at least one pair of electrodes of every at least one of the multiple semiconductor elements and the corresponding electrical contacts aligned therewith in a heating cycle by heat carried by the at least one energy beam in the heating cycle. The die-bonding method delivers scattering heated dots over the target substrate to avoid warpage of PCB and ensures high bonding strength between the semiconductor elements and the circuit structure of the target substrate.
