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.

Lintlha tsa Sehlahisoa

Li-tag tsa Sehlahisoa

Silicon carbide (SiC) thepa e le 'ngoe ea kristale e na le lekhalo le leholo la lekhalo la sehlopha (~ Si makhetlo a 3), conductivity e phahameng ea mocheso (~Si 3.3 linako kapa GaAs makhetlo a 10), tekanyo e phahameng ea ho falla ha elektronike (~ Si 2.5 linako), ho senyeha ho matla ha motlakase tšimo (~ Si 10 linako kapa GaAs 5 linako) le litšobotsi tse ling tse hlaheletseng.

Matla a Semicera a ka fana ka bareki ba boleng bo phahameng ba Conductive (Conductive), Semi-insulating (Semi-insulating), HPSI (High Purity semi-insulating) silicon carbide substrate; Ho phaella moo, re ka fana ka bareki ba nang le homogeneous le heterogeneous silicon carbide epitaxial sheets; Re ka boela ra iketsetsa leqephe la epitaxial ho latela litlhoko tse khethehileng tsa bareki, 'me ha ho na palo e fokolang ea taelo.
