Abstract
A surface-mounted light-emitting device includes: a LED epitaxial structure having two opposite surfaces, wherein the first surface is a light-emitting surface; P and N electrode pads over the second surface of the epitaxial structure, which have sufficient thickness to support the LED epitaxial structure, and the P and N electrode pads have two opposite surfaces respectively, in which, the first surface is approximate to the LED epitaxial structure; an insulator between the P and N pads to prevent the P and N electrode pads from short circuit; and the P and N electrode pads are directly applied in the SMT package. Some embodiments allow structural changes compared with conventional SMT package type by directly mounting the chip over the supporting substrate through an electrode pad. In addition, soldering is followed after the chip process without package step, which is mainly applicable to flip-chip LED device.
