A method of selectively transferring micro devices from a donor substrate to contact pads on a receiver substrate. Micro devices are attached to a donor substrate with a donor force. The donor substrate and receiver substrate are aligned and brought together so that selected micro devices meet corresponding contact pads. A receiver force is generated to hold selected micro devices to the contact pads on the receiver substrate. The donor force is weakened and the substrates are moved apart leaving selected micro devices on the receiver substrate. Several methods of generating the receiver forceare disclosed, including adhesive, mechanical and electrostatic techniques.
