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 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.Bolelele bo phahameng ba ho roala SiC re ka bo etsa 2640mm.

Li-tag tsa Sehlahisoa

Li-substrates tsa GaAs li arotsoe ka conductive le semi-insulating, tse sebelisoang haholo ka laser (LD), semiconductor light-emitting diode (LED), near-infrared laser, quantum well-high-power laser le liphanele tsa letsatsi tse sebetsang hantle haholo.HEMT le HBT chips bakeng sa radar, microwave, millimeter wave kapa likhomphutha tsa lebelo le phahameng haholo le puisano ea optical;Lisebelisoa tsa maqhubu a seea-le-moea bakeng sa puisano e se nang mohala, 4G, 5G, puisano ea sathelaete, WLAN.

Haufinyane tjena, li-substrates tsa gallium arsenide le tsona li hatetse pele haholo ho mini-LED, Micro-LED, le LED e khubelu, 'me li sebelisoa haholo lisebelisoa tse aparoang tsa AR/VR.
