Abstract
An LED chip is disclosed. The LED chip includes a substrate and a semiconductor element formed on the substrate. A recess is formed on the semiconductor element so as to expose a first-type of semiconductor layer thereof to the environment. The LED chip also includes a conductive layer disposed on a second-type semiconductor layer of the semiconductor element, a first electrode disposed in the recess and electrically connected to the first-type of semiconductor layer, and a second electrode disposed on the conductive layer. In addition, the LED chip includes a first circular electrode disposed on the conductive layer and extending along an edge of the substrate and electrically connected to the second electrode.
