Patent ID: 8624968

Claim:
A method of forming a microscope device comprising: forming a light emitting diode (LED) array comprising a plurality of LED core-shell structures with each LED core-shell structure comprising: a doped buffer layer disposed on a substrate, a growth mask dielectric disposed on the doped buffer layer, a nanowire core formed on the doped buffer layer through the growth mask dielectric, and a layered shell formed to envelop the nanowire core, wherein the layered shell comprises a multi-quantum-well (MQW) active region; forming a p-side semiconductor to envelop the layered shell of each LED core-shell structure; forming a p-side electrode having a thickness ranging from about 100 nm to about 500 nm to envelop the p-side semiconductor; filling a dielectric material between adjacent p-side electrodes for an electrical isolation, providing a surface comprising both the p-side electrodes and the dielectric material; inverting the LED array to attach the surface comprising both the p-side electrodes and the dielectric material to a readout integrated circuit (ROIC); removing the substrate of the LED array to expose the doped buffer layer; and patterning the doped buffer layer to form a plurality of n-side semiconductors on the growth mask dielectric with each n-side semiconductor connecting with the nanowire core of a corresponding LED core-shell structure.
