Iyini i-Quartz Boat?
A isikebhe se-quartziyisithwali esinembile esenziwe nge-silica ehlanganisiwe ehlanzekile kakhulu, ngokuvamile equkethe umklamo we-multi-slot. Isetshenziselwa ukubamba ama-silicon wafers, ama-semiconductor substrates, noma ezinye izinto ngesikhathi sezinqubo zokushisa okuphezulu. Ekukhiqizweni kwe-photovoltaic kanye ne-semiconductor, izikebhe ze-quartz zingamathuluzi abalulekile ezinqubo ezibalulekile njengokusabalalisa, ukufakwa komphunga wamakhemikhali (i-CVD), kanye nokufaka i-annealing, okuthinta ngqo ukusebenza kahle kokukhiqiza kanye nokukhiqizwa komkhiqizo.
Imisebenzi Eyinhloko:
I-Photovoltaics: Kusetshenziswa ekusakazweni kwe-phosphorus (ukwakha ama-PN junctions) kanye nokufakwa kwengqimba yokudlulisa ama-silicon wafers ezithandweni zokushisa okuphezulu.
Ama-semiconductor: Ithwala ama-wafer ngesikhathi sokushiswa, ukugqwala, kanye nokufakwa kwefilimu encane ekwakhiweni kwama-chip.
Isikebhe se-Quartz Saklanywa Futhi Sakhiwa Kanjani?
Umklamo weisikebhe se-quartz esithambilekumele ihlangabezane nezindinganiso ezilandelayo:
-Ubumsulwa Obuphezulu Kakhulu:
Izinto ze-SiO2 ezingavuthiwe kumele zidlule ubumsulwa obungu-99.99% ukuze kugwenywe ukungcola.

Ukuphelela Komphezulu:
Ukupholisha ngamathuluzi edayimane kufeza ubulukhuni bomphezulu (Ra) <0.5 μm, okunciphisa ukunamathela kwezinhlayiya.
Ukuwasha nge-asidi (isib. i-HCl) kususa izinto ezingcolisayo ezisele.
Ukuhlolwa Okuqinile:
Ukuhlolwa Kokushaqeka Kokushisa: Kuqhutshwa ngebhayisikili ngokushesha phakathi kuka-25℃ no-1200℃ ukuhlola ukumelana nokuqhekeka.
Ukuhlaziywa Kobumsulwa: I-Glow discharge mass spectrometry (GDMS) ithola ukungcola okumbalwa.
Kungani izikebhe ze-quartz zingenakufakwa esikhundleni sazo kulezi zimboni?
Ukungasebenzi Kwamakhemikhali: Imelana nokusabela ngama-acid, ama-alkali, i-chlorine, kanye namagesi enqubo emazingeni okushisa aphezulu.
Ukuzinza Kokushisa: Kungcono kakhulu kunezinsimbi noma izinto zobumba ekujikelezeni okusheshayo kokushisa ngenxa ye-CTE ephansi kakhulu.
Ukucaca Okubonakalayo: Ivumela ukudluliswa kokukhanya kwe-UV-IR kwezinqubo ze-CVD ezisizwa yisithombe.
Ukuqhathanisa:
Isikebhe se-Silicon Carbide (SiC): Izindleko eziphezulu kanye nokusabela kabusha nge-oxygen (kukhiqiza i-CO2).
Isikebhe seGraphite: Ingozi yokungcoliswa kwekhabhoni ethinta ukumelana kwe-wafer.
Izikebhe ze-quartz zisebenza kanjani emigqeni yokukhiqiza ye-photovoltaic?
Ukusabalala kwe-Phosphorus:
Inqubo: Ama-wafer e-silicon afakwa ezikebheni ze-quartz futhi afakwe kugesi we-POCl3 ku-850-950℃ ukuze akhe ama-PN junctions.
I-Quartz inokumelana nokugqwala okuphezulu kakhulu ezindaweni ezinolaka ze-POCl3.
Ukudlula Kweseli le-PERC:
Inqubo: Ibamba ama-wafer ngesikhathi sokufakwa kwe-Al2O3 ukuze kudlule umswakama ngemuva, okwandisa ukusebenza kahle kokuguqulwa.
Ipharamitha Ebalulekile: Umklamo wesikhala uqinisekisa ukufana kobukhulu befilimu ≤3%.
Izikebhe ze-quartz ziqinisekisa kanjani ukunemba ekucutshungulweni kwe-wafer?
Izinqubo Zokuxuba:
Inqubo: Ama-wafer alayishwa ngokuqondile esikebheni se-quartz ukuze kufakwe i-oxidation eyomile/emanzi ku-1100℃ ukuze kukhule izendlalelo ze-SiO2.
Isici Sokuklama: Izindonga zesikhala zigobile ku-5-10° ukuvimbela ukushelela kwe-wafer.
