Tlhaloso e Khutšoanyane:

WeiTai Energy Technology Co., Ltd. ke mofani oa thepa ea ka sehloohong ea sebetsanang le 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 mafapha 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 morekisi ea tšeptjoang, re utloisisa bohlokoa ba lisebelisoa tse ka sebelisoang ha ho etsoa tlhahiso, 'me re ikemiselitse ho fana ka lihlahisoa tse finyellang litekanyetso tsa boleng bo phahameng ka ho fetisisa ho phethahatsa litlhoko tsa bareki ba rona.
