4 Inch SiC Substrate N-mofuta

Tlhaloso e Khutšoanyane:

Semicera e fana ka mefuta e mengata ea li-wafers tsa 4H-8H SiC. Ka lilemo tse ngata, re bile moetsi le mofani oa lihlahisoa ho liindasteri tsa semiconductor le photovoltaic. Lihlahisoa tsa rona tsa mantlha li kenyelletsa: lipoleiti tsa silicon carbide etch, silicon carbide boat trailers, silicon carbide wafer boats (PV & Semiconductor), silicon carbide furnace tubes, silicon carbide cantilever paddles, silicon carbide chucks, silicon carbide libalaka, hammoho le CVD Coatings le SiC coating. Liaparo tsa TaC. E akaretsa boholo ba limmaraka tsa Europe le Amerika. Re labalabela ho ba molekane oa hau oa nako e telele Chaena.
