Method and device for repairing a semiconductor chip

A method for repairing a semiconductor chip, comprising:

• providing an LED module that includes a circuit substrate and a plurality of light-emitting units disposed on the circuit substrate and electrically connected to the circuit substrate;
• wherein at least one of the plurality of light-emitting units is a damaged light-emitting unit;
• removing the damaged light-emitting unit to form an unoccupied position;
• directing a laser source generated by a laser generating module to the damaged light-emitting unit to reduce the bonding force between the damaged light-emitting unit and the circuit substrate;
• using a pick and place module to remove the damaged light-emitting unit from the circuit substrate to form an unoccupied space;
• placing a good light-emitting unit into the unoccupied space using the pick and place module;
• and
• electrically connecting the good light-emitting unit to the circuit substrate.

A device for repairing a semiconductor chip, wherein the device for repairing a semiconductor chip is applied to an LED module including a circuit substrate and a plurality of light-emitting units disposed on the circuit substrate and electrically connected to the circuit substrate, with at least one of the plurality of light-emitting units being a damaged light-emitting unit, the device comprising:

• a laser generating module adjacent to the circuit substrate and disposed under the circuit substrate for generating a laser source;
• and
• a pick and place module adjacent to the light-emitting unit and disposed above the light-emitting unit;
• wherein the laser source generated by the laser generating module is directed to the damaged light-emitting unit to reduce the bonding force between the damaged light-emitting unit and the circuit substrate;
• wherein the pick and place module removes the damaged light-emitting unit from the circuit substrate to form an unoccupied space, and the pick and place module places a good light-emitting unit into the unoccupied space.
