ABSTRACT:
Techniques for controlling current flow in semiconductor devices, such as LEDs are provided. For some embodiments, a current guiding structure may be provided including adjacent high and low contact areas. For some embodiments, a second current path (in addition to a current path between an n-contact pad and a metal alloy substrate) may be provided. For some embodiments, both a current guiding structure and second current path may be provided.
