Changelight has 44 G4 MOCVD's with 430,000 4-inch ROY LED epi wafers annual capacity. That means one G4 produces ~10,000 4-inch wafers (2 runs a day) a year, not 20,000 wafers (4 runs a day). It also means the future AMTC plant will need 120 MOCVD to meet the 1.2m wafers (4-inch) annual output target, double from what i previously estimated. AMTC's Phase I plan of 1B yuan (128m Eur) investment would likely order a fraction of the final capacity. In 2017, Changelight ordered 20 G4 MOCVD's with a cost of 320m Yuan for its 650m Yuan ROY LED plant investment, or 50% of the investment goes to purchasing the MOCVD's. Accordingly, AMTC probably has 64m Eur allocated for MOCVD in 2020. |
