High-Purity Liquid Argon mu Semiconductor Manufacturing ndi Kalozera Wogula
Ndi chitukuko chofulumira chamakampani a semiconductor padziko lonse lapansi, njira zopangira chip zalowa munthawi ya nanometer. M'njira yolondola kwambiri yopangira izi, kusinthasintha kwakanthawi kochepa kwa chilengedwe kapena kusadetsedwa kwa zinthu kungayambitse kudulidwa kwa mtanda wonse wa zophika. Chifukwa chake, mpweya wapadera wamagetsi ndi mpweya wamafakitale woyenga kwambiri umagwira ntchito yosasinthika. Mwa iwo, mkulu chiyero madzi argon Chakhala chofunikira kwambiri chogwiritsidwa ntchito tsiku ndi tsiku cha nsalu za semiconductor chifukwa cha kusakhazikika kwake kwamankhwala komanso mawonekedwe ake abwino kwambiri.
Nkhaniyi isanthula mozama momwe madzi a argon amagwirira ntchito popanga chip ndikupereka kalozera waukadaulo wogulira magulu amakampani ogulitsa.
Mapulogalamu Apakati: Chifukwa Chiyani Liquid Argon Ndi Osalekanitsidwa ndi Semiconductor Manufacturing?
Pakupanga kwa Front-End-of-Line (FEOL) semiconductor kupanga, madzi argon a semiconductors amagwiritsidwa ntchito m'magawo otsatirawa omwe amatsimikizira zokolola:
- Kuyika Nthunzi Pathupi (PVD) / Kuphulika: Mpweya wapamwamba kwambiri wa argon, wopangidwa ndi gasification wa argon wamadzimadzi, ndiye mpweya wodziwika bwino kwambiri mumayendedwe a PVD sputtering. M'chipinda chopumuliramo, ma argon ion amafulumizitsidwa ndi gawo lamagetsi kuti aphulitse zomwe akufuna, zomwe zimapangitsa kuti maatomu omwe akuwayang'ana atuluke ndikuyikamo mofanana pamwamba pake kuti apange filimu yachitsulo. Kuyera kwakukulu ndikofunikira kuti muwonetsetse kuti kachulukidwe ndi kusasinthika kwamagetsi kwafilimuyi.
- Mwamtheradi Safe Inert Protective Atmosphere: Panthawi yokoka kwa silicon ya monocrystalline (monga ndondomeko ya Czochralski) ndi njira zowonjezera kutentha kwapamwamba, silicon imakhudzidwa mosavuta ndi mpweya pa kutentha kwakukulu. Chifukwa chake, mpweya wa argon uyenera kuyambitsidwa mosalekeza kuti ulowe m'malo mwa mpweya, ndikupereka malo opanda mpweya otalikirana ndi mpweya ndi chinyezi, potero kuwonetsetsa kukula kwabwino kwa silicon crystal lattice.
- Cryogenics ndi Wafer Cleaning Technology: M'njira zapamwamba monga Extreme Ultraviolet (EUV) lithography, mawonekedwe otsika kwambiri a kutentha kwa madzi a argon (kuwira -186 ° C) nthawi zina amagwiritsidwa ntchito pazida zoziziritsa bwino. Panthawi imodzimodziyo, ukadaulo wa argon aerosol umagwiritsidwanso ntchito poyeretsa pang'ono pang'ono nanometer pamiyala yopyapyala, yomwe imatha kuchotseratu tinthu tating'onoting'ono.
Ubwino Umatsimikizira Zokolola: Miyezo Yolimba ya High-Purity Liquid Argon
Zofunikira zamakampani a semiconductor pazinthu zopangira ndizovuta kwambiri. Argon wamba wamba wamafuta amadzimadzi nthawi zambiri amangofunika kufikira chiyero cha 99.9% kapena 99.99%, koma izi siziri kutali ndi kukwaniritsa zosowa zakupanga chip. Za oyenerera mkulu chiyero madzi argon, chiyero choyambirira chimafunika kuti chifike 99.999% (5N), ndipo m'malo apamwamba, chimafunikanso kufika 99.9999% (6N) kapena kupitirira.
Chofunikira kwambiri ndikuwongolera zoyipa. Zomwe zili mu mpweya, nayitrogeni, chinyezi, ma hydrocarboni okwana (THC), ndi ma ayoni achitsulo otsata zitsulo ziyenera kuyendetsedwa mosamalitsa pamlingo wa ppb (gawo pa biliyoni) kapena ppt (gawo pa thililiyoni). Ngakhale zitakhala zonyansa pang'ono pang'onopang'ono mupaipi ya gasi, zimatha kupanga zolakwika zazing'ono pamtunda, zomwe zimapangitsa kuti chip chifupikitse kapena kutayikira kwapano, kutsitsa mwachindunji kuchuluka kwa zokolola ndikubweretsa kuwonongeka kwakukulu kwachuma.
Upangiri Wogula: Momwe Mungawunikire Ndi Kusankha Katswiri Wamadzimadzi Argon Supplier?
Popeza gawo lalikulu la mpweya woyeretsedwa kwambiri pakugwira ntchito kwa mizere yopangira, kupeza ndi kupeza wothandizira wa argon wamadzi woyenerera komanso wokhoza ndi ntchito yayikulu pamagulu ogula ndi ogulitsa. Powunika omwe angakhale ogulitsa, tikulimbikitsidwa kuyang'ana magawo atatu awa:
Ulamuliro Wabwino Kwambiri ndi Mphamvu Zoyesa: Otsatsa abwino kwambiri ayenera kukhala ndi zida zowunikira zapamwamba kwambiri monga Gas Chromatographs (GC) ndi Mass Spectrometers (MS). Ayenera kupereka mwatsatanetsatane COA (Certificate of Analysis) pa batch iliyonse kuti atsimikizire kusasinthika koyera pakati pa zobereka.
Kulimba Kwambiri kwa Chain Supply Resilience ndi Kukhazikika Kwakatundu: Nsalu nthawi zambiri zimagwira ntchito 24/7/365, ndipo mtengo wanthawi yotsika ndi wokwera kwambiri. Chifukwa chake, ogulitsa ayenera kukhala ndi kuthekera kwakukulu kosungirako madzi komweko, magalimoto awo onyamula mafuta a cryogenic, ndi mapulani adzidzidzi adzidzidzi.
Advanced Containers and Anti-"Secondary Contamination" Technology: Ziribe kanthu kuti chiyero cha gasi ndi chokwera bwanji, sichikhala chothandiza ngati chaipitsidwa panthawi yamayendedwe. Cholinga chake chiyenera kukhala pa akasinja osungira a cryogenic ndi matekinoloje opangira ma tanker mkati (monga ngati adalandira chithandizo cha Electropolishing/EP), komanso Njira Zoyendetsera Ntchito (SOP) zotsuka ma valve ndi mapaipi panthawi yodzaza ndi kusamutsa, kuwonetsetsa kuti kuyeretsedwa kwakukulu kumatha kuperekedwa molunjika kuchokera ku fakitale kupita kumalo opangira makasitomala.
Mapeto
Pansi pa kupita patsogolo kosalekeza kwa Lamulo la Moore, argon amadzimadzi oyeretsedwa kwambiri sikuti amangogwiritsidwa ntchito, komanso ndi "kuperekeza kosawoneka" kwa njira zapamwamba za semiconductor. Kuwunika ndi kusankha mwasayansi ndi mokhwima a liquid argon supplier ndi mphamvu zonse zowonetsetsa kuti argon amadzimadzi amadzimadzi amadzimadzi amadzimadzi a argon a semiconductors ndiye mwala wapangodya pabizinesi iliyonse yopanga ma semiconductor kuti apititse patsogolo zokolola ndikupambana pamsika wapadziko lonse lapansi.
FAQ
Q1: Kodi kuwongolera kodetsa kumakhala kolimba bwanji pakuyeretsa kwamadzi argon komwe kumagwiritsidwa ntchito popanga semiconductor?
Yankho: Okhwima kwambiri. Semiconductor-grade liquid argon sikuti imangofunika chiyero chonse cha 99.999% (5N) kapena kupitilira apo, koma makamaka, imayika malire okhwima pazinyalala zinazake. Mwachitsanzo, kuchuluka kwa chinyezi (H2O) ndi oxygen (O2) nthawi zambiri kumafunika kusungidwa pansi pa 10 ppb; kwa 7nm ndi pansi pa mfundo zapamwamba, zonyansa za zitsulo zachitsulo zimafunikanso kulamulira ppt-level (gawo pa thililiyoni).
Q2: Posankha wogulitsa argon wamadzimadzi, kuipitsidwa kwachiwiri pamayendedwe ndi kusamutsa kungapewedwe bwanji?
Yankho: Chinsinsi chopewera kuipitsidwa kwachiwiri chili mu zida za hardware za woperekera katundu ndi momwe amagwirira ntchito. Pakugula zinthu, tsimikizirani ngati wogulitsa amagwiritsa ntchito matanki a cryogenic oyeretsedwa kwambiri operekedwa kwa semiconductors (liner yamkati imafunikira kupukutidwa kwapadera ndi kuwongolera). Pakadali pano, yang'ananinso SOP yawo kuti itsitse zamadzimadzi pamalopo, kuwonetsetsa kuti kuyeretsa kokwanira kwa gasi ndikusintha kumachitidwa musanalumikize mapaipi, komanso kuti zida zowunikira mpweya / chinyezi pa intaneti zili ndi zida.
Q3: Ndi kuwonongeka kwanji komwe kungadzetse pa chowotcha ngati madzi a argon a semiconductors sakukwaniritsa miyezo yoyera?
Yankho: Ngati chiyerocho ndi chocheperako (monga kusakaniza ndi trace oxygen kapena chinyezi), kumayambitsa kusayembekezeka kwa okosijeni pamwamba pa zowotcha za silicon panthawi yotentha kwambiri kapena kukoka magalasi. Mu PVD sputtering, zonyansa zidzasakanizidwa mufilimu yachitsulo yoyikidwa, kusintha filimuyo kuti iwonongeke komanso thupi. Izi zidzayambitsa kuwonongeka kwakupha monga mabwalo aafupi ndi mabwalo otseguka pawafa, kuchepetsa kwambiri zokolola za chip.
