Abstract: A light-emitting device includes a semiconductor stack, first and second insulative layers, a reflective conductive structure, and first and second pads. The semiconductor stack includes a first semiconductor layer, and a mesa having an active region having a second semiconductor layer and formed on the first semiconductor layer. The first insulative layer is formed on the semiconductor stack and has first openings. The reflective conductive structure is formed on the first insulative layer and is electrically connected to the second semiconductor layer through the first openings. The second insulative layer is formed on the reflective conductive structure and includes second openings and a contact area covering portions overlapped with the first and second openings. A first pad is formed on the second insulative layer and electrically connected to the first semiconductor layer. A second pad formed on the second insulative layer and electrically connected to the second semiconductor layer.
