ABSTRACT:
A first adhesive layer is provided on a base substrate, and multiple devices are arranged on the first adhesive layer. The first adhesive layer is irradiated with laser light from the back side of the base substrate, only at positions corresponding to the devices to be transferred, by use of a mask, whereby the adhesive force of the first adhesive layer is lowered only at these positions, and only these devices are made releasable from the base substrate. A transfer substrate provided with a second adhesive layer and the base substrate are so disposed that the devices and the second adhesive layer are opposite to each other and pressed against each other. When the transfer substrate is stripped from the base substrate, only the devices to be transferred are selectively transferred onto the transfer substrate.
