Abstract:
The disclosed technology relates generally to a method and system for micro assembling GaN materials and devices to form displays and lighting components that use arrays of small LEDs and high-power, high-voltage, and or high frequency transistors and diodes. GaN materials and devices can be formed from epitaxy on sapphire, silicon carbide, gallium nitride, aluminum nitride, or silicon substrates. The disclosed technology provides systems and methods for preparing GaN materials and devices at least partially formed on several of those native substrates for micro assembly.

Claim (Index 15):
A method of preparing printable materials for micro assembly from a native device substrate using an intermediate substrate having a controlled tackiness, the method comprising:\n depositing one or more materials on the native device substrate, thereby forming an epitaxial material; forming devices with the epitaxial material on the substrate; delineating releasable structures comprising the devices in the epitaxial material, thereby partially exposing the device substrate; forming anchoring structures and tethering structures such that the releasable structures are connected to the substrate by the anchoring structures and tethering structures following contact of the substrate with the etchant; temporarily bonding the epitaxial material to the intermediate substrate and performing a laser-lift off process, thereby separating the epitaxial material from the device substrate and thereby inverting the epitaxial material for micro assembly, wherein:\n the controlled tackiness of the intermediate substrate is configured so that a transfer element can remove the materials from the intermediate substrate for micro assembly, and \n the native substrate is transparent to laser illumination that is absorbed strongly by an absorbing layer on the native substrate so that upon exposure to the laser illumination the absorbing layer at least partially decomposes or otherwise forms an interface that can initiate separation between the native substrate and the devices for micro assembly; \n at least partially completing the formation or delineation of devices on the intermediate substrate; forming anchoring, tethering, or encapsulation structures insoluble to an etchant for releasing the epitaxial material from the intermediate substrate; releasing the devices from the intermediate substrate by removal of at least a portion of the selectively removable layer positioned between at least a portion of the intermediate substrate and at least a portion of the devices, thereby forming printable micro assemble-able devices from the native substrate via the intermediate substrate; and transferring the released materials for micro assembly on the intermediate substrate to a second intermediate stamp, thereby presenting the epitaxial material for micro assembly in a different un-inverted configuration, the second intermediate stamp also having controlled tackiness such that the second intermediate stamp can remove the materials for micro assembly from the intermediate stamp and a transfer element can remove the epitaxial material for micro assembly from the second intermediate stamp.
