Silicon Carbide Substrates | SiC Wafers

Tlhaloso e Khutšoanyane:

Semicera Energy Technology Co., Ltd. ke morekisi ea itlhommeng pele ea ipabolang ka li-wafer le lisebelisoa tse tsoetseng pele tsa semiconductor. Re inehetse ho fana ka lihlahisoa tsa boleng bo holimo, tse tšepahalang le tse ncha ho tlhahiso ea semiconductor, indasteri ea photovoltaic le likarolo tse ling tse amanang le tsona.

Mohala oa rona oa lihlahisoa o kenyelletsa lihlahisoa tsa graphite tse koahetsoeng ke SiC / TaC le lihlahisoa tsa ceramic, tse kenyelletsang lisebelisoa tse fapaneng tse kang silicon carbide, silicon nitride, le aluminium oxide joalo-joalo.

Hajoale, ke rona feela moetsi ea fanang ka bohloeki 99.9999% SiC coating le 99.9% recrystallized silicon carbide. The max SiC coating bolelele re ka etsa 2640mm.
