Claim:
1. A semiconductor device comprising: an n-type epitaxial semiconductor layer comprising a first surface and a second surface opposite the first surface; a p-type epitaxial semiconductor layer comprising a third surface and a fourth surface opposite the third surface; an active region between the second surface and the fourth surface; a wavelength conversion layer adjacent to at least a portion of the first surface of said n-type semiconductor layer, wherein the first surface is opposite the third surface of the p-type semiconductor layer; a p-electrode comprising a lead that is accessible on the third surface, the third surface being opposite of a primary emission surface of said semiconductor device, said p-electrode electrically connected to said p-type layer; an n-electrode comprising a lead that is accessible on the second surface, the second surface being opposite of said primary emission surface, said n-electrode electrically connected to said n-type layer; and at least one spacer element, coupled to the n-electrode and the p-electrode, such that the at least one spacer element electrically isolates the n-electrode from the p-electrode, in which the n-electrode and the p-electrode extend laterally over the at least one spacer element, wherein said first surface of said n-type epitaxial semiconductor layer is modified to enhance emission from said semiconductor device.
