Verticle’s Cu-base Hexagonal UV-LED Chip

Verticle Inc. extends its product line to UV LED. A new hexagonal shaped UV chip is made out of copper substrate enable to drive high current. Despite its numerous advantages, the main drawback of UV LED is lower optical power due to lower internal quantum efficiency (IQE). Since improving the IQE of UV epitaxial wafers is a long-term prospect, an alternative way to boost UV LED power is to drive more current into the UV-LEDs. However, heat generation is a big issue with high current drive. Moreover, aluminum containing UV epitaxial wafer is more res...
