AZZURRO Semiconductors AG Produces 150 mm GaN On Si On Thomas Swan CCS
AZZURRO Semiconductors AG is a spin-off of Prof. Alois Krost's renowned research team at the Otto-von-Guericke University, Magdeburg, Germany. The company manufactures gallium nitride (GaN) wafers with diameters of up to 150 mm for use in production as well as in R & D. Having pioneered the growth of GaN on silicon (Si) substrates, AZZURRO is focusing on the advantages of this technology.
AZZURRO is the first company in Germany which uses the Thomas Swan CCS system for GaN-based semiconductors, such as LEDs, on Si substrates. This exciting innovative technology is a promising approach to further reduce the manufacturing cost of LEDs. It has also the potential to prove the concept of the Hetero Wafer Technology, which combines the advantages of both, the silicon and the compound semiconductor worlds.
Dr. Armin Dadgar, CTO of AZZURRO Semiconductors AG who has just - for the first time - presented the successful growth of thick crack-free 150 mm GaN on Si wafers at the ICNS conference in Bremen, Germany commented on the importance of the reactor concept: "To guarantee the quality of our products and provide us with the flexibility to adapt to our customers' requirements, the Thomas Swan CCS MOCVD system is ideally suited. Moreover, the new in-situ wafer curvage measurement tool gives us even more control over the growth process, which is essential for large diameter growth as for our 150 mm GaN on Si wafers."
Dr. Bernd Schulte, Executive Vice President and COO of AIXTRON added: "This order is of strategic importance to us because it is placed by an ambitious new high-tech company. We are proud that the outstanding capabilities of the Thomas Swan CCS system which provides a reliable platform for GaN based semiconductors convinced yet another customer."
