Abstract
A method of transferring micro-devices is provided. A carrying unit including a carrying substrate, a plurality of electrodes, a dielectric layer covering the electrodes, and a plurality of micro-devices disposed on the electrodes, including a first micro-device and a second micro-device, are also provided. A voltage is applied to an electrode corresponding to the first micro-device, so that an electrostatic force generated on the first micro-device by the carrying unit is larger than a force generated on the second micro-device by the carrying unit. A transfer stamp contacts the first micro-device and the second micro-device, and moves when the transfer stamp contacts the first micro-device and the second micro-device and the electrostatic force is greater than the force generated by the carrying unit, so that the second micro-device is picked up by the transfer stamp and transferred to a receiving unit, and the first micro-device remains on the carrying unit.
