Semiconductor SiC dahaarka monocrystalline silicon epitaxial disk

Semiconductor SiC dahaarka monocrystalline silikoon epitaxial disk Sawirka leh

Sharaxaad Gaaban:

Semicera Energy Technology Co., Ltd. waa alaab-qeybiye hormuud ah oo ku takhasusay waferka iyo isticmaalka semiconductor sare.Waxaan u heellannahay inaan siino alaab tayo sare leh, la isku halayn karo, iyo halabuur leh wax-soo-saarka semiconductor,warshadaha photovoltaiciyo qaybaha kale ee la xidhiidha.

Khadkayaga alaabada waxaa ka mid ah alaabada graphite ee dahaarka leh ee SiC/TaC iyo alaabada dhoobada, oo ka kooban agabyo kala duwan sida silikoon carbide, silicon nitride, iyo aluminium oxide iyo iwm.

Bixiye la aamini karo, waxaan fahamsanahay muhiimada ay alaabooyinka u leeyihiin habka wax soo saarka, waxaana naga go'an inaan gaarsiinno alaabada buuxisa heerarka tayada ugu sarreeya si loo fuliyo baahiyaha macaamiisheena.

Sharaxaada

Shirkaddayadu waxay bixisaaDahaarka SiCadeegyada habka CVD ee dusha sare ee graphite, ceramics iyo alaabta kale, si gaasaska gaarka ah ee ay ku jiraan kaarboon iyo Silicon ay ka falceliyaan heerkulka sare si ay u helaan daahirsanaan sare SiC molecules, molecules lagu shubo dusha alaabta dahaarka ah, samaynta.lakabka ilaalinta SIC.

Tilmaamaha ugu muhiimsan

1. Iska caabbinta oksaydhka heerkulka sare:
caabbinta oksaydhisku weli aad bay u wanaagsan tahay marka heerkulku gaadho 1600 C.
2. Nadiifin sare: oo ay samaysay uumiga kiimikaad ee hoos yimaada xaalada koloriinaynta heerkulka sare.
3. Iska caabbinta nabaadguurka: adkaanta sare, dusha sare, qaybo yaryar.
4. Iska caabinta daxalka: acid, alkali, milix iyo reagents organic.
