Boti la Quartz: Chonyamulira Chofunika Kwambiri mu Makampani Opanga Photovoltaic ndi Semiconductor

Kodi Boti la Quartz ndi chiyani?

A bwato la quartzndi chonyamulira cholondola chopangidwa ndi silica yosakanikirana bwino kwambiri, nthawi zambiri imakhala ndi kapangidwe ka multi-slot. Chimagwiritsidwa ntchito kusungira ma silicon wafers, ma semiconductor substrates, kapena zinthu zina panthawi ya kutentha kwambiri. Pakupanga ma photovoltaic ndi ma semiconductor, maboti a quartz ndi zida zofunika kwambiri pazochitika zofunika monga kufalikira, chemical vapor deposition (CVD), ndi annealing, zomwe zimakhudza mwachindunji magwiridwe antchito opanga komanso phindu la zinthu.

Ntchito Zapakati:

Ma photovoltaic: Amagwiritsidwa ntchito pofalitsa phosphorous (kupanga ma PN junctions) ndi passivation layer deposition ya ma silicon wafers m'mauvuni otentha kwambiri.
Ma semiconductor: Amanyamula ma wafer panthawi yothira mafuta, kupukuta, ndi kuyika filimu yopyapyala popanga ma chip.

Kodi Boti la Quartz Limapangidwa Bwanji ndi Kupangidwa Bwanji?

Kapangidwe kabwato la quartzayenera kukwaniritsa izi:
-Kuyera Kwambiri:

Zinthu zosaphika za SiO2 ziyenera kupitirira 99.99% kuyera kuti zisaipitsidwe.

-Kukana Kutentha Kwambiri:

Pitirizani kukhudzidwa ndi kutentha kopitirira 1200℃ popanda kuwonongeka kwa kapangidwe kake.

-Kuwonjezeka kwa Kutentha Kochepa:

Kuchuluka kwa kutentha (CTE) kuyenera kuchepetsedwa (≈5.5 10-6/℃) kuti tipewe kupindika kapena kusweka.

-Kapangidwe ka Malo Oyenera Kwambiri:

Kulekerera kwa malo olowera kumayendetsedwa mkati mwa ± 0.1mm kuti zitsimikizire kutentha kofanana.

Kodi bwato la quartz limapangidwa bwanji?

Kuyeretsa Zinthu Zopangira:

Mchenga wachilengedwe wa quartz umasungunuka mu uvuni wamagetsi pa 2000°C kuti uchotse zinyalala monga Fe, Al, ndi Na.

Njira Zopangira:

Makina a CNC: Zipangizo zoyendetsedwa ndi kompyuta zimadula mipata ndi kulondola kwa sub-millimeter.
Kuponya Nkhungu: Pa ma geometries ovuta, silika yosakanikirana imathiridwa mu nkhungu za graphite ndikusungunuka.

Ungwiro Wapamwamba:

Kupukuta pogwiritsa ntchito zida za diamondi kumapangitsa kuti pamwamba pakhale povuta (Ra) <0.5 μm, zomwe zimachepetsa kumatirira kwa tinthu tating'onoting'ono.
Kutsuka ndi asidi (monga HCl) kumachotsa zotsalira za zinthu zodetsa.

Kuyesa Kokhwima:

Kuyesa Kugwedezeka kwa Kutentha: Kuyendetsedwa mofulumira pakati pa 25℃ ndi 1200℃ kuti muwone ngati ming'alu ikulimbana.
Kusanthula kwa Chiyero: Glow discharge mass spectrometry (GDMS) imazindikira zonyansa zochepa.

N’chifukwa chiyani maboti a quartz sangasinthidwe m’mafakitale amenewa?

Kusagwira Ntchito kwa Mankhwala: Imakana kuyanjana ndi ma acid, alkali, chlorine, ndi mpweya wopangira zinthu kutentha kwambiri.

Kukhazikika kwa Kutentha: Ndizabwino kwambiri kuposa zitsulo kapena zoumbaumba pa kutentha kwachangu chifukwa cha CTE yotsika kwambiri.

Kuwonekera Kwa Maso: Imalola kutumiza kuwala kwa UV-IR kwa njira za CVD zothandizidwa ndi chithunzi.

Kuyerekeza:

Bwato la Silicon Carbide (SiC): Mtengo wokwera komanso kuchitapo kanthu ndi mpweya (kumapanga CO2).

Bwato la Graphite: Kuopsa kwa kuipitsidwa kwa kaboni komwe kungakhudze kukana kwa wafer.

Kodi maboti a quartz amagwira ntchito bwanji mumizere yopanga ma photovoltaic?

Kufalikira kwa Phosphorus:
Njira: Ma wafer a silicon amalowetsedwa m'maboti a quartz ndipo amaikidwa mu mpweya wa POCl3 pa kutentha kwa 850-950℃ kuti apange ma PN junction.
Quartz ili ndi kukana dzimbiri kwabwino kwambiri motsutsana ndi malo amphamvu a POCl3.

Kusakhazikika kwa Maselo a PERC:
Njira: Imasunga ma wafers panthawi ya Al2O3deposition kuti igwire ntchito kumbuyo, zomwe zimapangitsa kuti ntchito yosinthira ikhale yogwira mtima.
Chofunika Kwambiri: Kapangidwe ka malo kamatsimikizira kufanana kwa makulidwe a filimu ≤3%.

Kodi maboti a quartz amaonetsetsa bwanji kuti zinthu zophikidwa bwino zikugwiritsidwa ntchito molondola?

Njira Zothira Ma Oxidation:
Njira: Ma wafer amalowetsedwa molunjika mu boti la quartz kuti asungunuke/kunyowa pa kutentha kwa 1100℃ kuti akule zigawo za SiO2.
Kapangidwe kake: Makoma opingasa ali ndi ngodya pa 5-10° kuti asagwedezeke ndi wafer.

Njira za CVD:
Njira: Imalola kugawa kwa plasma mofanana panthawi ya Si3N4 kapena polysilicon deposition.
Zatsopano: Mapangidwe apamwamba amaphatikiza njira zoyendera mpweya kuti filimu ikhale yolimba.

Ndi njira ziti zomwe zimawonjezera moyo wa boa ya quartz pomwe zimachepetsa nthawi yopuma?

Kuyeretsa Nthawi:
Tsiku ndi tsiku: Kuyeretsa madzi oyeretsedwa ndi CO2 kumachotsa tinthu totayirira.

Sabata iliyonse: Kumiza mu 5% citric acid pa 80℃ kumasungunula zitsulo zosungunuka.

Mndandanda Wowunikira:
Kusinthika: Madontho oyera pa quartz amasonyeza kupangika kwa kristalo; sinthani ngati kuphimba kupitirira 5%.
Ming'alu yaing'ono: Gwiritsani ntchito mayeso olowetsa utoto kuti mupeze zolakwika pansi pa nthaka.

Kodi ndi zinthu ziti zomwe zingathandizenso ukadaulo wa bwato la quartz?

Maboti Oyendetsedwa ndi IoT:
Masensa a Bragg grating (FBG) ophatikizidwa ndi ulusi amawunika kutentha kwa nthawi yeniyeni (kulondola kwa ±1°C).

Zophimba Zapamwamba:
Zophimba za Yttria-stabilized zirconia (YSZ) zimachepetsa kuchuluka kwa silicon carbide ndi 70% mu epitaxial reactors.

Kupanga Zowonjezera:
Maboti a quartz osindikizidwa mu 3D okhala ndi ma lattice opangidwa ndi ma lattice achepetsa kulemera ndi 40% pamene akusunga mphamvu.

Kuyambira poyambitsa minda ya dzuwa ya terawatt mpaka kuyambitsa kusintha kwa AI kudzera mu ma semiconductor apamwamba,bwato la quartzndi ntchito yodzikuza kwambiri yaukadaulo wamakono. Pamene mafakitale akukankhira malire a kuchepetsedwa kwa mphamvu ndi kugwira ntchito bwino, zatsopano mu kapangidwe ka maboti a quartz ndi sayansi ya zinthu zidzakhalabe zofunika kwambiri—kutsimikizira kuti ngakhale m'nthawi ya AI ndi quantum computing, zipangizo zina "zakale" zidakali ndi makiyi a tsogolo.
