Massively parallel transfer of microLED devices
20180190614 · 2018-07-05 ·

MicroLED devices can be transferred in large numbers to form microLED displays using processes such as pick-and-place, thermal adhesion transfer, or fluidic transfer. A blanket solder layer can be applied to connect the bond pads of the microLED devices to the terminal pads of a support substrate. After heating, the solder layer can connect the bond pads with the terminal pads in vicinity of each other. The heated solder layer can correct misalignments of the microLED devices due to the transfer process.
