Abstract
A method of forming and testing a plurality of monolithic electronic devices is provided. As part of the method a monolithic device array comprising Group III-nitrides is formed on a sacrificial substrate. A test substrate comprising electrical contacts is aligned with electrical contacts of the monolithic device array and bonded to the monolithic device array via bonding dielectric layers. Power is supplied from the test substrate to test the monolithic devices of the monolithic device array. Portions of the sacrificial substrate are then selectively removed to separate each of the monolithic electronic devices, wherein a sacrificial dielectric layer is removed to separate each monolithic electronic device from the test substrate.
