  • Patent number: 11862502
    Abstract: A device, apparatus, and method for semiconductor transfer are provided. A transfer substrate is controlled to be moved to be above the target substrate. An infrared emitting portion emits infrared signals to position a semiconductor on a target substrate. After a second magnetic portion picks up the semiconductor from the target substrate, a controller outputs a first control current to a first electromagnetic portion to cause the first electromagnetic portion to generate an electromagnetic force, to control the second magnetic portion to adjust a position of the picked-up semiconductor relative to the welding position on the target substrate, where adjusting the position of the picked up semiconductor includes horizontal adjustment.
