Abstract
A method of transferring micro devices is provided. A carrier substrate having a first surface and a second surface opposite to each other is provided, wherein a plurality of micro devices is disposed on the first surface, and each micro device binds to the first surface through laser debonding gel. Next, a receiving substrate is subjected to be relatively closer to the first surface, and a mask is provided on the second surface. Afterwards, the second surface with the mask is irradiated with a laser light, so as to keep the micro devices without laser irradiation binding on the first surface, and the micro devices irradiated with the laser light lose adhesive force and transfer to the receiving substrate.
Claims9
A method of transferring micro devices, comprising:
- providing a carrier substrate having a first surface and a second surface opposite to each other, wherein a plurality of micro devices is disposed on the first surface, and each of the plurality of micro devices binds to the first surface through a laser debonding gel, the laser debonding gel is coated on the first surface continuously;
- subjecting a receiving substrate to the first surface and providing a mask on the second surface;
- and
- irradiating the second surface with the mask with a laser light, so as to keep the plurality of micro devices without laser irradiation binding on the first surface, and the plurality of micro devices irradiated with the laser light loses adhesive force and transfers to the receiving substrate.
