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 photovoltaicle masimo a mang a amanang.

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.

Joaloka mofani oa thepa ea tšepahalang, re utloisisa bohlokoa ba thepa e ka sebelisoang ha ho etsoa tlhahiso, 'me re ikemiselitse ho fana ka lihlahisoa tse finyellang litekanyetso tsa boleng bo holimo ho phethahatsa litlhoko tsa bareki ba rona.
