AIXTRON to Support LED and Laser Research at Peking University

AIXTRON SE announced that China’s Peking University is adding to its AIXTRON equipment base with an order for a further Close Coupled Showerhead (CCS) reactor with capacity for three 2-inch (3x2”) substrates in a single run. The order was made in the second quarter of 2012 with delivery scheduled for the first quarter of 2013.


One of the researchers who will be using the AIXTRON system is Professor Shen Bo. He says: “We already have an AIXTRON CCS system in use, and we are very satisfied with it. We now needed a system to improve our UV LED and laser research. The aluminium gallium nitride (AlGaN) material growth needed for this is very challenging due to the very high temperatures of more than 1200°C required. Also AlGaN is very difficult to dope, particularly with magnesium that is used to create the p-type regions needed for hole injection.”

AIXTRON’s Close Coupled Showerhead® (CCS) concept is an excellent tool for small scale production and R&D. Processes are easily scaleable to larger systems. The stable platform comes with excellent reliability, ease of use and reproducibility.
