Patent ID: 8362521

Claim:
At least two discrete III-nitride semiconductor devices noncontiguously coexisting as grown simultaneously on a principal face of a starting substrate and lacking only electrodes in order to function as semiconductor devices, each III-nitride semiconductor device comprising: a III-nitride semiconductor crystal substrate 10 μm to 600 μm in thickness and 0.2 mm to 50 mm in width, formed in atomic layers of elemental nitrogen and of a Group III element alternating in the <0001>direction of said starting substrate such that the III-nitride semiconductor device lower surface, being a back-side principal face thereof in contact with the principal face of said starting substrate, is nitrogen-terminating; and at least one device-forming III-nitride semiconductor crystal layer grown onto a front-side principal face of said III-nitride semiconductor crystal substrate reverse from its back-side principal face; wherein applying either chemical or mechanical separation means to said at least two discrete III-nitride semiconductor devices, as lacking semiconductor-device electrodes, separates said at least two discrete III-nitride semiconductor devices from said starting substrate.
