Patent ID: 8361880

Claim:
A method for fabricating a semiconductor light-emitting device, the method comprising: etching a Si growth substrate to produce mesas; fabricating on a multilayer structure on at least one of the mesas, wherein the multiplayer structure comprises a first doped layer, an active layer, and a second doped layer; fabricating a first Ohmic-contact layer configured to form a conductive path to the first doped layer; fabricating a second Ohmic-contact layer configured to form a conductive path to the second doped layer; fabricating a support substrate layer above the multilayer structure, wherein the support substrate comprises not less than 15% Cr measured in weight percentage and iron, wherein the support substrate has a thickness that is between 10 microns and 200 microns, and wherein the support substrate is in direct contact with the first Ohmic-contact layer, thereby enabling the semiconductor light-emitting device to have vertical electrodes; and removing the Si growth substrate that comprises mesas.
