Abstract:
1. A light-emitting device, comprising: a semiconductor layer sequence comprising a first semiconductor layer having a first electrical conductivity, a second semiconductor layer having a second electrical conductivity, and an active layer interposed between the first semiconductor layer and the second semiconductor layer; a protruding structure; a beveled trench in the semiconductor layer sequence and accommodating the protruding structure; a dielectric layer on the second semiconductor layer and an inner sidewall of the beveled trench; a first metal layer on the dielectric layer and contacting with the first semiconductor layer, wherein the first metal layer is insulated from the second semiconductor layer by the dielectric layer; a void formed between the first metal layer and the protruding structure; a carrier substrate; and a first connection layer connecting the carrier substrate and the semiconductor layer sequence, wherein the second semiconductor layer is closer to he carrier substrate than the first semiconductor layer is to the carrier substrate.
