A high performance, highly reflective ohmic contact, in the visible spectrum
(400
nm-750 nm), has the following multi-layer metal profile. A uniform and thin ohmic
contact material is deposited and optionally alloyed to the semiconductor surface.
A thick reflector layer selected from a group that includes Al, Cu, Au, Rh, Pd,
Ag and any multi-layer combinations is deposited over the ohmic contact material.
