A bright future for LEDs

A bright future for LEDs

By Institution of Engineering and Technology

In the latest issue of Electronics Letters, a team from Suzhou Institute of Nano-tech and Nano-bionics, Chinese Academy of Sciences, Xiangneng HuaLei Optoelectronic Co. Ltd. and several Universities in China, report successful creation of a single wafer level LED chip producing more than 150W output, using a single chip assembly approach.

In single chip assembly, integrated circuits are created on a wafer substrate as normal, but are then assembled without being separated from the wafer. This approach allows the creation of LED chips with areas a hundred times bigger than the highest-power LED chips previously produced.
