Abstract:
1. A device transfer method comprising: generating a laser beam from a laser light source; reflecting with a reflection section the laser beam generated from said laser light source toward a required direction, wherein the reflection section is oscillated over a fixed angle; uniformizing with a scanning lens light entering said scanning lens; controlling with a control section whether or not the laser beam is to be irradiated in an interlocking relationship with said reflection section, the scanning lens being interposed between said reflection section and said control section; and selectively irradiating the laser beam on a plurality of devices arranged on a transfer source substrate so that the devices that are selected are transferred to a transfer destination substrate by laser ablation caused by the irradiation of the laser beam, wherein a light intensity distribution of the laser beam is a Gaussian distribution.
