Abstract:
The present invention provides a method and a device for repairing semiconductor chips. The method includes providing an LED module including a circuit substrate and a plurality of light-emitting units; driving the light-emitting units by a signal generator; measuring at least one light-emitting unit by a feature detector module so as to obtain an abnormal feature and define the at least one light-emitting unit as a bad light-emitting unit having the abnormal feature; projecting a laser light source generated by a laser generating module onto the bad light-emitting unit; removing the bad light-emitting unit from the circuit substrate by a chip pick-and-place module to form a vacancy; placing a good light-emitting unit inside the vacancy by the chip pick-and-place module; and electrically connecting the good light-emitting unit to the circuit substrate. Therefore, the bad light-emitting unit is replaced by the good light-emitting unit for repairing the LED module.

Claim (Index 1):
A method for repairing semiconductor chips, comprising:\n providing an LED module that includes a circuit substrate and a light-emitting group disposed on the circuit substrate and electrically connected to the circuit substrate, wherein the light-emitting group includes a plurality of light-emitting units, each light-emitting unit includes an LED chip and a conductive substance disposed between a bottom side of the LED chip and the circuit substrate; providing the LED module with a predetermined signal generated by a signal generator so as to drive the light-emitting units; measuring at least one of the light-emitting units by a feature detector module so as to obtain an abnormal feature and define the at least one light-emitting unit as a bad light-emitting unit having the abnormal feature; projecting a laser light source generated by a laser generating module onto the bad light-emitting unit so as to decrease the bonding strength between the bad light-emitting unit and the circuit substrate; removing the bad light-emitting unit from the circuit substrate by a chip pick-and-place module so as to form a vacancy on the light-emitting group; placing a good light-emitting unit inside the vacancy of the light-emitting group by the chip pick-and-place module, wherein the good light-emitting unit includes a good LED chip and a new conductive substance disposed on a bottom side of the good LED chip; and projecting the laser light source generated by the laser generating module onto the good light-emitting unit so as to fix the good light-emitting unit on the circuit substrate and electrically connect the good light-emitting unit to the circuit substrate.
