工藝流程 ProcessFlow

石墨舟及硅片準備→管內充氮氣→進舟→抽真空、壓力測試→氨氣預清理和檢查→管路抽真空、測漏、恒溫→預鍍膜→鍍膜→抽真空、壓力測試→清管路、充氮氣→退舟
Graphite boat & wafers ready→Nitrogen inlet→Graphite boat load in→Vacuumize, pressure test →Ammonia pre-clean and check→Vacuumize the tube,leak-checking , constant temperature→Pre-coating →Coating→Vacuumize,pressure test→Tube cleaning and Nitrogen inlet→Graphite boat unload.
