Classification: CPC H | IPC H

Claim 0:
1. An ultraviolet laser diode device operable at a wavelength of less than 380 nm and greater than 200 nm, the ultraviolet laser diode device comprising:
a handle substrate member comprising a surface region;
an interface region overlying the surface region;
a first transparent conductive oxide material with a band gap energy of greater than 3.2 eV and less than 7.5 eV overlying the interface region;
a p-type aluminum, gallium, and nitrogen containing material;
an active region comprising aluminum, gallium, and nitrogen containing material overlying the p-type aluminum, gallium, and nitrogen containing material; and
an n-type aluminum, gallium, and nitrogen containing material;
wherein a process of forming the ultraviolet laser diode device comprises:
bonding the interface region to the surface region; and
subjecting a release material to an energy source to initiate release of the n-type aluminum, gallium, and nitrogen containing material from the release material.
