    Abstract: A surface-mounted light-emitting device is fabricated by epitaxial growth: forming the LED epitaxial structure over a growth substrate through epitaxial growth; chip fabrication: determining P and N electrode regions and an isolating region over the LED epitaxial structure surface and fabricating the P and N electrode pads and the insulator over the P and N electrode regions and the isolating region, wherein the P and N electrode pads have sufficient thicknesses to support the LED epitaxial structure, and the insulator is formed between the P and N electrode pads to prevent the P and N electrode pads from a short circuit; removing the growth substrate and unitizing the LED epitaxial structure to form the chip; and SMT packaging: providing the supporting substrate and directly mounting the P and N electrode pads of the chip over the supporting substrate through SMT packaging to thereby form the surface-mounted LED light-emitting device.

    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.

    Abstract: A light-emitting diode (LED) device includes a substrate, an electrically conductive layer, a first LED chip, and an anti-electrostatic discharge element. The substrate has opposite upper and lower surfaces. The electrically conductive layer is formed on the upper surface of the substrate, and has first and second regions that are electrically separated from each other by a trench structure. The trench structure has a first segment and a second segment which connects and is not collinear with the first segment. The first LED chip is disposed across the first segment, and the anti-electrostatic discharge element is disposed across the second segment, both interconnecting the first and second regions.
