Fellow co-founder Atsushi Nishikawa, CTO of Allos, said: "Already our predecessor company Azzurro had been first in the market with commercial 150mm and later 200mm GaN-on-Si epiwafer products. Making 300mm was the next natural challenge. When the first reactor designed for such large wafers, the Veeco ImPulse, became available we proceeded to tackle the challenge."
