Abstract: A semiconductor device is provided, which includes an epitaxial structure, a first contact electrode and a second contact electrode. The epitaxial structure includes a first semiconductor structure, a second semiconductor structure and an active region. The first semiconductor structure includes a first semiconductor contact layer. The second semiconductor structure includes a second semiconductor contact layer. The active region is located between the first semiconductor structure and the second semiconductor structure. The first contact electrode is located on the second semiconductor contact layer and directly contacts the first semiconductor contact layer. The second contact electrode is located on the second semiconductor contact layer and directly contacts the second semiconductor contact layer. The first semiconductor contact layer has a conductivity type of n-type and includes a first group III-V semiconductor material. The second semiconductor contact layer has a conductivity type of p-type and includes a second group III-V semiconductor material.
