Claim 10:
11. A method of self-assembling a plurality of semiconductor light-emitting devices, the method comprising:
Transferring an assembly substrate to an assembly position of a self-assembly apparatus, and placing the plurality of semiconductor light-emitting devices into a fluid chamber of the self-assembly apparatus;
applying a magnetic force to the plurality of semiconductor light-emitting devices to move the plurality of semiconductor light-emitting devices along one direction in the fluid chamber;
applying an electric field to guide the plurality of semiconductor light-emitting devices to preset positions of the assembly substrate so as to allow the plurality of semiconductor light-emitting devices to be seated at the preset positions on the assembly substrate during the movement of the plurality of semiconductor light-emitting devices; and
shooting a fluid to some of the plurality of semiconductor light-emitting devices to allow the some of the plurality of semiconductor light-emitting devices seated on the assembly substrate to be separated from the assembly substrate, when the some of the plurality of semiconductor light-emitting devices are not seated at the preset positions of the assembly substrate,
wherein the shooting of the fluid to the some of the plurality of semiconductor light-emitting devices comprises:
placing a fluid injector having at least one hole into the fluid chamber so that the least one hole is oriented upwards in a direction opposite to gravity caused by a gravitational force of the earth; and
transferring the fluid injector to allow the at least one hole to face the some the plurality of semiconductor light-emitting devices, and then shooting the fluid out the at least one hole upwards towards the some of the plurality of semiconductor light-emitting devices.
