Up to now our research group, ISCAS, has been using our first AIXTRON system and they are very satisfied with the system's all round performance. Now, however, we need a new capability that gives us high throughput but with lower cost and easy operation. We are convinced that we will get all these features and more from the world-class CRIUS® MOCVD reactors supplied by AIXTRON.
