Kodi Boti la Quartz ndi chiyani?
A bwato la quartzndi chonyamulira cholondola chomwe chimapangidwa ndi silica yosakanikirana bwino kwambiri, yomwe imakhala ndi mapangidwe ambiri. Amagwiritsidwa ntchito kunyamula zowotcha za silicon, magawo a semiconductor, kapena zida zina panthawi yotentha kwambiri. Popanga ma photovoltaic ndi semiconductor, mabwato a quartz ndi zida zofunika kwambiri panjira zovuta monga kufalikira, kutulutsa mpweya wamankhwala (CVD), ndi kuphatikizira, zomwe zimakhudza mwachindunji kupanga bwino komanso zokolola.
Core Functions:
Zithunzi za Photovoltais: Amagwiritsidwa ntchito mu phosphorous diffusion (kupanga PN mphumu) ndi passivation wosanjikiza mafunsidwe kwa silicon wafers mu ng'anjo mkulu kutentha.
Ma semiconductors: Imanyamula zowotchera panthawi ya oxidation, etching, ndi kuyika filimu yopyapyala pakupanga chip.
Kodi Boti la Quartz Linapangidwa Bwanji Ndi Kupangidwa Bwanji?
Mapangidwe abwato la quartzakuyenera kukwaniritsa izi:
-Kuyera Kwambiri Kwambiri:
Zinthu zaiwisi za SiO2 ziyenera kupitilira 99.99% chiyero kuti zipewe kuipitsidwa.
-Kukana Kutentha Kwambiri:
Kupirira kutentha kwanthawi yayitali kuposa 1200 ℃ popanda kuwonongeka kwamapangidwe.
-Kukula Kwamafuta Otsika:
Coefficient of thermal expansion (CTE) iyenera kuchepetsedwa (≈5.5 10-6/℃) kuti mupewe kugwedezeka kapena kusweka.
-Precision Slot Design:
Kulolerana kwa malo otsetsereka kumayendetsedwa mkati mwa ± 0.1mm kuti zitsimikizire kutentha kofanana.
Kodi boti la quartz limapangidwa bwanji?
Kuyeretsedwa kwa Zinthu Zaiwisi:
Mchenga wachilengedwe wa quartz umasungunuka mu ng'anjo yamagetsi yamagetsi pa 2000 ° C kuchotsa zonyansa monga Fe, Al, ndi Na.
Njira Zopangira:
CNC Machining: Zida zotsogozedwa ndi makompyuta zimasema mipata yolondola kwambiri ya millimeter.
Kuponya Mould: Kwa ma geometri ovuta, silika wosakanikirana amatsanuliridwa mu nkhungu za graphite ndikuwotchedwa.
Ungwiro Pamwamba:
Kupukuta kwa chida cha diamondi kumakwaniritsa nkhanza (Ra) <0.5 μm, kuchepetsa kumatira kwa tinthu.
Kutsuka kwa asidi (mwachitsanzo, HCl) kumachotsa zotsalira zotsalira.
Kuyesa Kwambiri:
Kuyeza Kugwedezeka kwa Matenthedwe: Kuyenda mwachangu pakati pa 25 ℃ ndi 1200 ℃ kuti muwone kukana kwa ming'alu.
Kusanthula Koyera: Glow discharge mass spectrometry (GDMS) imazindikira zonyansa.
Chifukwa chiyani mabwato a quartz sangalowe m'malo mwa mafakitale awa?
Chemical Inertness: Imakana kuchitapo kanthu ndi zidulo, alkalis, klorini, ndi mipweya yopangira kutentha kwambiri.
Kutentha Kukhazikika: Zapamwamba kwambiri kuposa zitsulo kapena zoumba mu kupalasa njinga mwachangu chifukwa cha CTE yotsika kwambiri.
Optical Transparency: Imalola kufalikira kwa kuwala kwa UV-IR panjira zothandizidwa ndi zithunzi za CVD.
Kuyerekezera:
Silicon Carbide (SiC) Boti: Mtengo wokwera komanso kuyambiranso ndi mpweya (amapanga CO2).
Boti la Graphite: Kuwopsa kwa kuipitsidwa kwa kaboni komwe kumakhudza kukhazikika kwa wafer.
Kodi mabwato a quartz amagwira ntchito bwanji mumizere yopanga ma photovoltaic?
Kuchuluka kwa Phosphorous:
Njira: Zophika za silicon zimakwezedwa m'mabwato a quartz ndikuwonetsedwa ndi mpweya wa POCl3 pa 850-950 ℃ kuti apange ma PN junctions.
Quartz ili ndi kukana kwamphamvu kwa dzimbiri motsutsana ndi malo ankhanza a POCl3.
PERC Cell Passivation:
Njira: Imagwirizira zowotcha nthawi ya Al2O3deposition kuti ipitirire kumbuyo, kukulitsa kutembenuka mtima.
Critical Parameter: Kapangidwe ka slot kumatsimikizira makulidwe a filimu ≤3%.
Kodi mabwato a quartz amawonetsetsa bwanji kukonzedwa kwawafer?
Njira za Oxidation:
Njira: Ma Wafer amalowetsedwa mu bwato la quartz kuti azitha kuyamwa / kunyowa oxidation pa 1100 ℃ kuti akule zigawo za SiO2.
Mawonekedwe a Kapangidwe: Makoma olowera amakhomedwa pa 5-10 ° kuti ateteze kutsetsereka kwa wafer.
Njira za CVD:
Njira: Imathandizira kugawa kwa plasma yunifolomu pa Si3N4 kapena polysilicon deposition.
Zatsopano: Mapangidwe apamwamba amaphatikiza njira zoyendetsera gasi kuti filimu isasinthe.
Ndi machitidwe ati omwe amawonjezera moyo wa quartz boa ndikuchepetsa nthawi yopuma?
Kuyeretsa Cycles:
Tsiku ndi tsiku: Kuyeretsa madzi osungunula + CO2 kuyeretsa jeti ya chipale chofewa kumachotsa tinthu tating'ono.
Mlungu uliwonse: Kumizidwa mu 5% citric acid pa 80 ℃ kumasungunula ma oxide achitsulo.
Mndandanda Wowunika:
Devitrification: Mawanga oyera pa quartz amasonyeza crystallization; sinthani ngati kufalikira kupitilira 5%.
Ma Microcracks: Gwiritsani ntchito kuyezetsa kolowera utoto kuti muwone zolakwika zapansi panthaka.
Ndi zopambana ziti zomwe zidzafotokozerenso ukadaulo wa boti la quartz?
Maboti Othandizidwa ndi IoT:
Makanema ophatikizidwa a fiber Bragg grating (FBG) amawunika kutentha kwanthawi yeniyeni (± 1°C kulondola).
Zopaka Zapamwamba:
Yttria-stabilized zirconia (YSZ) zokutira zimachepetsa silicon carbide buildup ndi 70% mu epitaxial reactors.
Kupanga Zowonjezera:
Maboti a quartz osindikizidwa a 3D okhala ndi ma lattice amadula kulemera ndi 40% ndikusunga mphamvu.
Mapeto
Kuchokera pakuthandizira minda ya solar ya terawatt-scale mpaka kulimbikitsa kusintha kwa AI kudzera pa ma semiconductors apamwamba,bwato la quartzndi akavalo onyada aukadaulo wamakono. Pamene mafakitale akukankhira malire a miniaturization ndi mphamvu, zatsopano zamaboti a quartz ndi sayansi ya zinthu zidzakhalabe zofunika kwambiri-kutsimikizira kuti ngakhale m'zaka za AI ndi quantum computing, zipangizo zina za "sukulu zakale" zimakhalabe ndi makiyi amtsogolo.
