Ubwato bwa Quartz ni iki?
A ubwato bwa quartzni ubwikorezi bwuzuye bukozwe muri silika-isukuye cyane, isanzwe igaragaramo igishushanyo mbonera. Ikoreshwa mu gufata wafer ya silicon, insimburangingo ya semiconductor, cyangwa ibindi bikoresho mugihe cy'ubushyuhe bwo hejuru. Mu gukora Photovoltaque na semiconductor, ubwato bwa quartz nibikoresho byingenzi mubikorwa byingenzi nko gukwirakwiza, imyuka ya chimique (CVD), hamwe na annealing, bigira ingaruka kuburyo butaziguye no gutanga umusaruro.
Imikorere yibanze:
Amashusho: Byakoreshejwe mugukwirakwiza fosifore (kugirango habeho imiyoboro ya PN) hamwe na passivation layer yoherejwe na wafer ya silicon mumatara yubushyuhe bwo hejuru.
Amashanyarazi: Itwara wafer mugihe cya okiside, kurigata, no gushira firime yoroheje muguhimba chip.
Nigute ubwato bwa Quartz bwateguwe kandi bukorwa?
Igishushanyo cyaquartz wafer ubwatoigomba kuba yujuje ibi bikurikira:
-Ultra-Yera:
Ibikoresho bya SiO2 bigomba kurenga 99,99% byera kugirango wirinde kwanduza.
-Kurwanya Ubushyuhe Bwinshi:
Ihangane igihe kirekire guhura nubushyuhe buri hejuru ya 1200 ℃ nta kwangirika kwimiterere.
-Kwiyongera k'ubushyuhe buke:
Coefficient yo kwagura ubushyuhe (CTE) igomba kugabanywa (≈5.5 10-6 / ℃) kugirango wirinde guturika cyangwa guturika.
-Igishushanyo mbonera:
Kwihanganira umwanya muto bigenzurwa muri ± 0.1mm kugirango ushushe kimwe.
Nigute ubwato bwa quartz bukorwa?
Isuku ry'ibikoresho:
Umusenyi wa quartz karemano ushonga mumatara ya arc yumuriro kuri 2000 ° C kugirango ukureho umwanda nka Fe, Al, na Na.
Gushiraho Ubuhanga:
Imashini ya CNC: Ibikoresho biyobowe na mudasobwa bibaza ahantu hamwe na milimetero zuzuye.
Gushushanya Mold: Kuri geometrike igoye, silika ihujwe isukwa mubishushanyo bya grafite hanyuma bigacumura.
Ubuso bwuzuye:
Diyama-igikoresho cyo gusya kigera ku buso (Ra) <0.5 μ m, kugabanya uduce duto duto.
Gukaraba aside (urugero, HCl) ikuraho umwanda usigaye.
Ikizamini gikomeye:
Kwipimisha Ubushyuhe bwa Thermal: Byihuta byizunguruka hagati ya 25 ℃ na 1200 ℃ kugirango barebe ko birwanya.
Isesengura ryera: Glow isohora mass spectrometry (GDMS) itahura umwanda.
Kuki ubwato bwa quartz budasimburwa muruganda?
Ubusembwa bwa Shimi: Irwanya reaction hamwe na acide, alkalis, chlorine, hamwe na gaze itunganya ubushyuhe bwinshi.
Ubushyuhe bwumuriro: Biruta kure cyane ibyuma cyangwa ubukerarugendo mumagare yihuta yubushyuhe bitewe na ultra-low CTE.
Gukorera mu mucyo: Emerera UV-IR kohereza urumuri kubikorwa bifasha CVD.
Kugereranya:
Ubwato bwa Silicon Carbide (SiC): Igiciro kinini hamwe na reactivite hamwe na ogisijeni (itanga CO2).
Ubwato bwa Graphite: Ingaruka zo kwanduza karubone zigira ingaruka kuri wafer.
Nigute ubwato bwa quartz bukora mumirongo yumusaruro wamafoto?
Ikwirakwizwa rya Fosifore:
Inzira: Wafer ya Silicon yapakiwe mubwato bwa quartz kandi ihura na gaze ya POCl3 kuri 850-950 ℃ kugirango ihuze PN.
Quartz ifite imbaraga zo kurwanya ruswa irwanya ibidukikije bya POCl3.
PERC Passivation:
Inzira: Ifata wafers mugihe cya Al2O3deposition yo gusubira inyuma-passivation, kuzamura imikorere ihinduka.
Ibipimo by'ingenzi: Igishushanyo mbonera cyerekana ubunini bwa firime ≤3%.
Nigute ubwato bwa quartz buteganya neza mugutunganya wafer?
Inzira ya Oxidation:
Inzira: Wafers ihagaritswe mubwato bwa quartz kugirango okiside yumye / itose kuri 1100 ℃ kugirango ikure ibice bya SiO2.
Igishushanyo mbonera: Urukuta rucuramye rufite 5-10 ° kugirango wirinde kunyerera.
Inzira ya CVD:
Inzira: Gushoboza gukwirakwiza plasma imwe mugihe cya Si3N4 cyangwa polysilicon.
Guhanga udushya: Ibishushanyo mbonera bikubiyemo imiyoboro ya gazi kugirango ihindurwe neza.
Ni ubuhe buryo bwongerera igihe cya quartz boa igihe cyo kugabanya igihe?
Isuku:
Buri munsi: Amazi ya Deionized + CO2 isukura indege ikuraho uduce duto duto.
Icyumweru: Kwibiza muri 5% acide citric kuri 80 ℃ bishonga okiside yicyuma.
Kugenzura Urutonde:
Devitrification: Ibibara byera kuri quartz byerekana kristu; gusimbuza niba ubwishingizi burenze 5%.
Microcracks: Koresha irangi ryinjira kugirango umenye inenge zo munsi.
Ni izihe ntambwe zizasobanura tekinoroji ya quartz?
Ubwato bwa IoT:
Fibre yashyizwemo ibyuma bya Bragg grating (FBG) bikurikirana ubushyuhe bwigihe nyacyo (± 1 ° C neza).
Kwambara neza:
Yttria-stabilized zirconia (YSZ) igabanya silicon karbide kwiyubaka 70% mumashanyarazi ya epitaxial.
Gukora inyongeramusaruro:
Ubwato bwa 3D bwacapwe bwa quartz hamwe nububiko bwa lattice bugabanya ibiro 40% mugihe gikomeza imbaraga.
Umwanzuro
Kuva mu gushoboza imirasire y'izuba ya terawatt kugeza ingufu za AI binyuze mumashanyarazi yateye imbere,ubwato bwa quartzni amafarashi y'akazi adasuzuguritse ya tekinoroji igezweho. Mugihe inganda zitera imbibi za miniaturizasiya no gukora neza, guhanga udushya mubwubatsi bwa quartz hamwe na siyanse yibikoresho bizakomeza kuba ingenzi-byerekana ko no mugihe cya AI na comptabilite, ibikoresho bimwe na bimwe "bishaje-ishuri" biracyafite urufunguzo rw'ejo hazaza.
