Abstract

The invention discloses a semiconductor chip repairing method and a semiconductor chip repairing device. The semiconductor chip repair method includes: providing a light-emitting diode module, the light-emitting diode module includes a circuit substrate and a plurality of light-emitting units, at least one of the plurality of light-emitting units is a damaged light-emitting unit; and then, using a laser generation module to generate A laser light source is directed at the damaged light-emitting unit to reduce the bonding force between the damaged light-emitting unit and the circuit substrate; then, a chip pick-and-place module is used to remove the damaged light-emitting unit from the circuit substrate to form a vacancy; Next, use the chip pick-and-place module to place a good light-emitting unit into the vacancy; then, electrically connect the good light-emitting unit to the circuit substrate. In this way, the damaged light-emitting unit can be replaced by a good light-emitting unit to achieve a repair effect.

Description

technical field [0001] The invention relates to a chip repair method and a chip repair device, in particular to a semiconductor chip repair method and a semiconductor chip repair device. Background technique [0002] Currently, light-emitting diodes (Light-Emitting Diodes, LEDs) are widely used due to their good light quality and high luminous efficiency. Generally speaking, in order to make the display device using light-emitting diodes as light-emitting components have better color performance capabilities, the prior art uses red, green and blue light-emitting diode chips to form a full-color light-emitting diode chip. Display equipment, this full-color light-emitting diode display device can emit red, green, and blue three-color light through red, green, and blue light-emitting diode chips, and then form a full-color light after mixing light. to display relevant information. However, in the prior art, when the LED chip fixed on the circuit substrate is damaged, the dama...
