LIGHT-EMITTING DIODE CHIP

摘要

A light-emitting diode chip including a semiconductor device layer, a first electrode, a current-blocking layer, a current-spreading layer, and a second electrode is provided. The semiconductor device layer includes a first-type doped semiconductor layer, a second-type doped semiconductor layer, and a light-emitting layer located between the first-type and second-type doped semiconductor layers. The first electrode is electrically connected to the first-type doped semiconductor layer. The current-blocking layer is disposed on the second-type doped semiconductor layer, and the current-blocking layer includes a main body and an extension portion extended from the main body. The current-spreading layer covers the current-blocking layer. The second electrode is electrically connected to the second-type doped semiconductor layer via the current-spreading layer, wherein the second electrode includes a bonding pad and a finger portion extended from the bonding pad, the bonding pad is located above the main body, the finger portion is located above the extension portion, and a partial region of the finger portion does not overlap the extension portion.
