    • A light-emitting device comprises a substrate, an epitaxial structure formed on the substrate including a first semiconductor layer, a second semiconductor layer, and a light-emitting layer formed between the first semiconductor layer and the second semiconductor layer. A trench is formed in the epitaxial structure to expose a part of side surface of the epitaxial structure and a part of surface of the first semiconductor layer, so that a first conductive structure is formed on the part of surface of the first semiconductor layer in the trench, and a second conductive structure is formed on the second semiconductor layer. The first conductive structure includes a first electrode and a first pad electrically contacted with each other. The second conductive structure includes a second electrode and a second pad electrically contacted with each other. Furthermore, the area of at least one of the first pad and the second pad is between 1.5×104 μm2 and 6.2×104 μm2.
    • 发光器件包括衬底,形成在衬底上的外延结构,包括第一半导体层,第二半导体层和形成在第一半导体层和第二半导体层之间的发光层。 在外延结构中形成沟槽以暴露外延结构的侧面的一部分和第一半导体层的表面的一部分,使得第一导电结构形成在第一半导体层的表面的一部分中 沟槽,并且在第二半导体层上形成第二导电结构。 第一导电结构包括彼此电接触的第一电极和第一焊盘。 第二导电结构包括彼此电接触的第二电极和第二焊盘。 此外,第一焊盘和第二焊盘中的至少一个的面积在1.5×10 4μm2和​​6.2×10 4μm2之间。
