Abstract: A method of transferring micro-devices includes selectively treating a first adhesive layer to form a treated portion and an untreated portion while micro-devices are attached the first adhesive layer. A second adhesive layer on a second surface is placed to abut the micro-devices. The first adhesive layer is exposed to illumination in a region that overlaps at least some of the treated portion and at least some of the untreated portion. Exposing the first adhesive layer to illumination neutralizes the at least some of the untreated portion to create a neutralized portion that is less adhesive than an exposed area of the treated portion. The first surface is separated from the second surface such that micro-devices in the treated portion remain attached to the first surface and micro-devices in the neutralized portion are attached to the second surface and separate from the first surface.
