Semiconductor Quartz: Chigawo Chofunikira mu Zamagetsi Zamakono
Chiyambi cha Zida za Quartz
Quartz (SiO₂) ingafanane ndi galasi poyang'ana koyamba, koma mawonekedwe ake apadera amasiyanitsa. Mosiyana ndi galasi lokhazikika, lomwe lili ndi zigawo zingapo (monga mchenga wa quartz, borax, barium carbonate, laimu, feldspar, ndi soda), quartz imapangidwa ndi SiO₂ yokha. Izi zimapatsa mawonekedwe osavuta amtaneti opangidwa ndi ma tetrahedral mayunitsi a silicon dioxide.
Kufunika kwa Quartz Yoyera Kwambiri
Quartz yoyera kwambiri, yomwe nthawi zambiri imatchedwa "korona" wa zida zamagalasi, imapereka zinthu zapadera chifukwa cha zonyansa zake zochepa zachitsulo. Zinthu zochititsa chidwizi ndizofunikira pamachitidwe osiyanasiyana a semiconductor, kudzitamandira zabwino monga:
1. Kulimbana ndi Kutentha Kwambiri: Ndi malo ochepetsera pafupifupi 1730 ° C, quartz imatha kupirira kugwiritsidwa ntchito kwa nthawi yaitali pa 1150 ° C ndikugwira kuphulika kwafupipafupi mpaka 1450 ° C.
2. Chemical Corrosion Resistance: High-purity quartz imasonyeza reactivity yochepa ndi ma acid ambiri (kupatula hydrofluoric acid) ndipo imasonyeza kukhazikika kwapamwamba polimbana ndi kuukira kwa mankhwala, kukhala 30 nthawi zambiri za asidi-zosagwirizana ndi zoumba ndi nthawi 150 kuposa zitsulo zosapanga dzimbiri.
3. Kukhazikika kwa Matenthedwe: Quartz yoyera kwambiri imakhala ndi mphamvu yowonjezera yowonjezera kutentha, yomwe imalola kuti ipirire kutentha kwachangu popanda kusweka.
4. Kuwala Kwambiri: Izi zimasunga kufalikira kwakukulu kudera lonse, ndi kuwala kowoneka bwino kupitirira 93% ndi ma ultraviolet transmittance kufika pamwamba pa 80%.
5. Kusungunula kwamagetsi: Quartz yoyera kwambiri imapereka kukana kwamagetsi kwapadera, kumapangitsa kuti ikhale insulator yabwino kwambiri ngakhale pa kutentha kwakukulu.
Mapulogalamu mu Semiconductor Viwanda
Chifukwa cha zinthu zakuthupi ndi zamankhwala zapamwambazi, quartz yoyera kwambiri imagwiritsidwa ntchito kwambiri mumagetsi amakono, matelefoni, komanso mafakitale a semiconductor. Kufunika kokulira kwa zowotcha za silicon kwawonjezera kufunikira kwa zida za quartz, makamaka pakupanga chip.
Ntchito Zofunikira za Quartz mu Semiconductor Manufacturing:
1. Zida Zotentha Kwambiri:
·Machubu a Quartz Furnace:Zofunikira pamachitidwe monga kufalikira, makutidwe ndi okosijeni, ndi kuphatikizika, machubuwa amatsimikizira kukhazikika kwa kutentha komanso kuchita bwino pakapangidwe ka semiconductor.
Maboti a Quartz:Amagwiritsidwa ntchito kunyamula ndi kukonza zowotcha za silicon, mabwato a quartz amathandizira kupanga batch munjira zoyatsira.
2. Zida Zosatentha:
*Ma mphete a Quartz:Kuphatikiza pa etching, mphete za quartz zimalepheretsa kuipitsidwa ndikuwonetsetsa kupangidwa bwino panthawi ya lithography ndi mapeni.
·Mabasiketi otsuka a Quartz ndi Matanki:Zidazi ndizofunikira pakuyeretsa zowotcha za silicon. Ayenera kukana asidi ndi alkali pomwe akuchepetsa malo olumikizirana kuti apititse patsogolo kuyeretsa.
Mapeto
Ngakhale zida za quartz zitha kuwoneka ngati zogwiritsidwa ntchito pang'ono popanga semiconductor, zimagwira ntchito yofunika kwambiri pakuwonetsetsa kuti zida za semiconductor zili bwino komanso zodalirika. Malinga ndi Techcet, zida zagalasi za quartz zoyera kwambiri zimakhala pafupifupi 90% ya zomwe zimapangidwa pachaka padziko lonse lapansi pamakampani azidziwitso zamagetsi.
Ku Semicera, tadzipereka kupititsa patsogolo malonda a semiconductor popereka zida za quartz zapamwamba kwambiri. Monga momwe misomali imafunikira kuti pakhale umphumphu, momwemonso quartz pakupanga semiconductor.
2. Zida Zotentha Zotsika:
·mphete za Quartz: Kuphatikiza pa etching, mphete za quartz zimalepheretsa kuipitsidwa ndikuwonetsetsa kupangidwa kolondola panthawi ya lithography ndi zojambulajambula.
·Mabasiketi Otsuka a Quartz ndi Matanki: Zidazi ndizofunikira pakuyeretsa zowotcha za silicon. Ayenera kukana asidi ndi alkali pomwe akuchepetsa malo olumikizirana kuti apititse patsogolo kuyeretsa.
