Abstract: The present disclosure relates to a transfer and bonding method using a laser. As a plurality of devices or packages are simultaneously transferred onto a substrate from a transfer tape by irradiating a top surface of the transfer tape with a first laser, and the plurality of transferred devices or packages are simultaneously bonded to pads of a substrate by irradiating a top surface of the devices or packages with a second laser, a speed of a transfer and bonding process may be extremely maximized.
