Abstract
A semiconductor device includes a semiconductor stack comprising a surface, and an electrode structure comprises an electrode pad formed on the surface, and the electrode structure further comprises a first extending electrode, a second extending electrode and a third extending electrode connecting to the electrode pad. The first extending electrode is closer to a periphery of the surface than the third extending electrode is, and the second extending electrode is between the first extending electrode and the third extending electrode. From a top view of the semiconductor device, the first extending electrode, the second extending electrode and the third extending electrode respectively include a first curve having a first angle θ, a second curve having a second angle θand a third curve having a third angle θ, wherein θ
