Abstract: A method of selectively transferring devices arrayed on a first substrate to a second substrate on which an adhesive resin layer is previously formed is provided. The method includes steps of selectively heating the adhesive resin layer on the second substrate by laser irradiation from the back surface side of the second substrate, and curing the selectively heated portions of the adhesive resin layer, thereby adhesively bonding those to be transferred of the devices to the second substrate.

The heated portions of the adhesive resin layer selectively exhibit the adhesive forces. The heated portions of the adhesive layer are then cured, so that only the devices to be transferred are selectively transferred to the second substrate.
