Chii chinonzi Quartz Boat?
A chikepe chequartzimotokari inogadzirwa ne silica yakasanganiswa ne high-purity, inowanzo kuve ne multi-slot design. Inoshandiswa kubata silicon wafers, semiconductor substrates, kana zvimwe zvinhu panguva yekupisa kwakanyanya. Mukugadzira photovoltaic uye semiconductor, quartz boats zvishandiso zvakakosha pakuita zvinhu zvakakosha zvakaita sekupararira, chemical vapor deposition (CVD), uye annealing, zvichikanganisa zvakananga kushanda zvakanaka kwekugadzira uye goho rezvigadzirwa.
Mabasa Epakati:
Photovoltaics: Inoshandiswa mukupararira kwephosphorus (kugadzira maPN junctions) uye passivation layer deposition ye silicon wafers muzvitofu zvinopisa zvakanyanya.
Masekendakita: Inotakura mawafer panguva yekuoxidation, etching, uye thin-film inoiswa mukugadzirwa kwemachip.
Chikepe cheQuartz Chinogadzirwa Sei uye Chinogadzirwa Sei?
Dhizaini yechikepe chewafer chequartzinofanira kuzadzisa zvinotevera:
-Kuchena Kwakanyanya:
Zvinhu zvisina kucheneswa zveSiO2 zvinofanira kudarika 99.99% kuchena kuti zvisasvibiswe.
-Kuramba Kupisa Kwakanyanya:
Ramba uchigara uchisangana netembiricha dzinopfuura 1200℃ kwenguva refu pasina kuora kwechimiro.
-Kuwedzera Kwekupisa Kwakaderera:
Coefficient of thermal expansion (CTE) inofanira kuderedzwa (≈5.5 10-6/℃) kudzivirira kutsemuka kana kutsemuka.
-Dhizaini yeSlot Yakanyatsogadzirwa:
Kushivirira kwenzvimbo dzema slot kunodzorwa mukati me±0.1mm kuti ive nechokwadi chekuti kupisa kwakafanana.
Chikepe che quartz chinogadzirwa sei?
Kucheneswa Kwezvinhu Zvisina Kugadzirwa:
Jecha re quartz rechisikigo rinonyungudutswa muchoto chemagetsi che arc pa 2000°C kubvisa tsvina yakaita seFe, Al, naNa.
Maitiro Ekugadzira:
Kugadzira CNC: Zvishandiso zvinotungamirirwa nekombiyuta zvinogadzira mipata ine kunyatsojeka kwe sub-millimeter.
Kugadzira Mould: Kune ma geometries akaomarara, silica yakasanganiswa inodururwa mu graphite molds yopiswa.
Kukwana Kwepamusoro:
Kupukuta maturusi edhaimani kunoita kuti pave nekuomarara kwepamusoro (Ra) <0.5 μm, zvichideredza kunamira kwezvikamu.
Kusuka neasidhi (semuenzaniso, HCl) kunobvisa tsvina yasara.
Kuedzwa Kwakasimba:
Kuedza Kuvhunduka Kwekupisa: Kunofambiswa nekukurumidza pakati pe25℃ ne1200℃ kuti utarise kuramba kwekuputika.
Kuongorora Kuchena: Glow discharge mass spectrometry (GDMS) inoona tsvina shoma.
Sei magwa e quartz asingatsiviwi mumaindasitiri aya?
Kusashanda kwemakemikari: Inodzivirira kusangana nemaacid, alkalis, chlorine, uye magasi ekugadzira zvinhu pakupisa kwakanyanya.
Kugadzikana kweThermal: Zviri nani kupfuura simbi kana ceramics mukupisa kunokurumidza nekuda kweCTE yakaderera zvakanyanya.
Kujeka Kwemaziso: Inobvumira kutapurirana kwechiedza cheUV-IR kune maitiro eCVD anobatsira nemufananidzo.
Kuenzanisa:
Chikepe cheSilicon Carbide (SiC): Mutengo wakakwira uye reactivity ne oxygen (inogadzira CO2).
Chikepe cheGraphite: Njodzi yekusvibiswa nekabhoni inokanganisa kusimba kwewafer.
Mabhoti e quartz anoshanda sei mumitsetse yekugadzira photovoltaic?
Kupararira kwePhosphorus:
Maitiro: Mawafer esilicon anoiswa mumagwa equartz uye anoiswa mugasi rePOCl3 pa850-950℃ kuti agadzire maPN junctions.
Quartz ine simba guru rekudzivirira ngura kubva kunzvimbo dzine hukasha dzePOCl3.
Kusagadzikana kweSero rePERC:
Maitiro: Inobata mawafer panguva yeAl2O3deposition kuti ipfuure kumashure, zvichiwedzera kushanda zvakanaka kwekushandura.
Chinonyanya Kukosha: Dhizaini yeslot inoita kuti ukobvu hwefirimu hufanane ≤3%.
Magwa e quartz anoita sei kuti pave nekunyatsogadzirwa kwe wafer?
Maitiro eOxidation:
Maitiro: Mawafer anoiswa muchikepe chequartz akamira kuti aome/anyorove pa1100℃ kuti akure SiO2 layers.
Chimiro Chekugadzira: Madziro enzvimbo akakombama pa 5-10° kudzivirira kutsvedza kwewafer.
Maitiro eCVD:
Maitiro: Inogonesa kugoverwa kweplasma kwakafanana panguva yeSi3N4 kana kuiswa kwepolysilicon.
Kugadzira zvinhu zvitsva: Magadzirirwo epamusoro anosanganisira nzira dzekufambisa magasi kuti firimu rive rakafanana.
Ndezvipi zvinhu zvinoita kuti quartz boa irambe ichirarama ukuwo ichideredza nguva yekuzorora?
Kucheneswa Kwenguva Dzose:
Zuva nezuva: Kuchenesa chando chechando nemvura yakabviswa maion + CO2 kunobvisa zvidimbu zvisina kusimba.
Vhiki nevhiki: Kunyudza mu 5% citric acid pa 80℃ kunonyungudutsa metal oxides.
Rondedzero yekuongorora:
Kuchinja kwemavara: Mavara machena pa quartz anoratidza kupenya kwekristalo; tsiva kana kufukidzwa kwacho kuchipfuura 5%.
Microcracks: Shandisa dhayi penetrant test kuti uone zvikanganiso zviri pasi pevhu.
Ndezvipi zvinhu zvichachinja tekinoroji yebhoti re quartz?
Mabhoti Ane IoT-Enabled:
Masensa eBragg grating (FBG) akagadzirwa nefiber anotarisa ma gradients ekupisa panguva chaiyo (±1°C akarurama).

Kugadzira Zvimwe:
Magwa equartz akadhindwa ne3D ane zvivakwa zve lattice akaderedza huremu ne40% uku achiramba akasimba.
Mhedziso
Kubva pakugonesa mapurazi ezuva ane terawatt-scale kusvika pakusimbisa shanduko yeAI kuburikidza nema semiconductors epamusoro,chikepe chequartzndiyo hunyanzvi husina muganho hwetekinoroji yemazuva ano. Sezvo maindasitiri achisimudzira miganhu yekushandiswa kwezvidiki uye kushanda zvakanaka, hunyanzvi mukugadzira ngarava dzequartz nesainzi yezvinhu zvicharamba zvichikosha—zvichiratidza kuti kunyangwe munguva yeAI ne quantum computing, zvimwe zvinhu "zvekare" zvichiri nemakiyi eramangwana.
