Light-emitting device

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 &#x3b8;, a second curve having a second angle &#x3b8;and a third curve having a third angle &#x3b8;, wherein &#x3b8;

Semiconductor device

A light-emitting device comprises a carrier; and a first semiconductor element comprising a first semiconductor structure and a second semiconductor structure, wherein the second semiconductor structure is closer to the carrier than the first semiconductor structure is to the carrier, the first semiconductor structure comprises a first MQW structure configured to emit a first light having a first dominant wavelength during normal operation, and the second semiconductor structure comprises a second MQW structure configured not to emit light during normal operation.
