Abstract:
1. A device arraying method of re-arraying a plurality of devices arrayed on a first substrate to a second substrate, the method comprising the steps of: a first transferring step including transferring the devices from the first substrate to a temporarily holding member such that the devices are spaced from each other with a pitch larger than a pitch of the devices arrayed on the first substrate and holding the devices on the temporarily holding member; a device isolation step including covering the devices held on the temporarily holding member with a resin and isolating the devices covered with the resin from each other; an adhesive layer forming step including forming an adhesive layer containing a light absorbing material for increasing a light absorptivity against laser beams on the second substrate or disposing the light absorbing material in proximity of the adhesive layer; and a second transferring step including selectively heating the adhesive layer on the second substrate by irradiating the devices to be transferred with laser beams passing through the second substrate, thereby transferring the devices to be transferred of the devices covered with the resin on the temporarily holding substrate to the second substrate.
