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 34):
A method of preparing released materials for micro assembly from a native sapphire substrate via an intermediate substrate, the method comprising:\n preparing materials for micro assembly by epitaxial growth on the native sapphire substrate to form an epitaxial material; forming at least one of anchoring, tethering, and encapsulation structures insoluble to an etchant for releasing the materials for micro assembly from the intermediate substrate; adhering the materials for micro assembly to an intermediate substrate to form a bonded pair of substrates; performing a laser-lift off process, thereby separating the materials for micro assembly from the native sapphire substrate and separating the bonded pair of substrates, wherein:\n the materials for micro assembly are thereby inverted, and \n the sapphire substrate is transparent to laser illumination that is absorbed strongly by an absorbing layer on the sapphire substrate such 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 sapphire substrate and the materials for micro assembly; and \n releasing the materials for micro assembly from the intermediate substrate by removing at least a portion of a selectively removable layer positioned between at least a portion of the intermediate substrate and at least a portion of the materials for micro assembly with the releasing etchant, thereby removing the selectively removable layer underneath the releasable structures and forming released, micro assemble-able GaN materials or devices from sapphire native substrates via the intermediate substrate.
