发光装置
摘要：
本发明公开一种发光装置，其包含：一基板；一透明导电层，设置于基板上；一半导体窗户层，形成于透明导电层上且具有一平坦表面及多个凹槽，其中每一凹槽具有一侧壁表面；及一发光叠层，形成于半导体窗户层上且包含一第一半导体层、一第二半导体层、一位于第一和第二半导体之间的活性层。此些凹槽中的至少其中一个的侧壁表面相对于平坦表面倾斜，且平坦表面与透明导电层之间的接触电阻小于侧壁表面与透明导电层之间的接触电阻。
摘要（英）：

A light-emitting device comprising a semiconductor light-emitting stack, comprising a light emitting area; an electrode formed on the semiconductor light-emitting stack, wherein the electrode comprises a current injected portion and an extension portion; a current blocking structure formed between the current injected portion and the semiconductor light-emitting stack, and formed between a first part of the extension portion and the semiconductor light-emitting stack; and an electrical contact structure formed between a second part of the extension portion and the semiconductor light-emitting stack.
