Mu dziko la microscopic la kupanga ma semiconductor, kulondola ndiye lamulo lalikulu. Pamene ukadaulo wa chip process ukupita patsogolo mu nthawi ya 2-nanometer, ngakhale kusintha pang'ono kwa muyeso kungayambitse kuchotsedwa kwa ma wafers onse, zomwe zimapangitsa kuti ndalama zambiri zisawonongeke. Potengera izi, "ma gauges" omwe amagwira ntchito ngati metrological references amachita gawo lofunika kwambiri. Ngakhale ma gauges achikhalidwe achitsulo amagwiritsidwa ntchito kwambiri, pang'onopang'ono akuwulula zofooka zawo akakumana ndi zofunikira kwambiri zamakampani a semiconductor zaukhondo, kukana dzimbiri, komanso kukhazikika. Ma gauges a ceramic, omwe ali ndi mphamvu zawo zapadera zakuthupi ndi zamankhwala, akukhala "oteteza osawoneka" ofunikira kwambiri mu metrology ya semiconductor, kupereka yankho losintha pochepetsa zolakwika zoyezera.
Kupitirira Chitsulo: Ubwino Wachilengedwe wa Zoyezera za Ceramic
Malo opangira zinthu zamagetsi zamagetsi (semiconductor) amaika zofunikira kwambiri pa zipangizo zoyezera. Ma blocks achitsulo akale, ngakhale kuti ali ndi kuuma kokwanira, amatha kuchita dzimbiri akamayikidwa m'malo ogwirira ntchito kwa nthawi yayitali ndipo nthawi zambiri amakopa tinthu ta maginito—chiwopsezo chachikulu popanga ma wafer osavuta kugwiritsa ntchito. Mosiyana ndi zimenezi, ma gauge olondola a ceramic—makamaka omwe amapangidwa kuchokera ku zirconia ndi alumina—amaonetsa ubwino waukulu.
Choyamba, zipangizo zadothi zimakhala ndi khalidwe lachilengedwe la "dzimbiri lopanda dzimbiri". M'zipinda zoyera kapena m'ma laboratories owunikira zinthu za semiconductor, kusinthasintha kwa chinyezi n'kosapeweka. Ma gauge achitsulo amafunika kupakidwa mafuta pafupipafupi kuti apewe dzimbiri, ndipo kupezeka kwa filimu yamafuta kumasintha mwachindunji kukula kwa gauge, zomwe zimayambitsa zolakwika zoyezera. Ma gauge adothi amachotsa chiopsezochi kwathunthu, kusunga malo okhazikika popanda kufunikira chitetezo cha mafuta. Kachiwiri, ma ceramic si maginito. Mu kuwunika komwe kumakhudza zigawo zamagetsi zodziwika bwino, kukopa kwa maginito kumatha kugwira zinyalala zazing'ono zachitsulo, zomwe sizimangokanda pamwamba poyezera gauge komanso zimadetsa pamwamba pa wafer. Ma gauge adothi amaletsa kusokoneza kwa maginito, kuonetsetsa kuti kukhudzana ndi kuyera kuli koyera.
Chofunika kwambiri, pali kukana kutopa. Kafukufuku akusonyeza kuti kukana kutopa kwa malo ogwirira ntchito a ceramic ndi kopitilira nthawi 10 kuposa chitsulo. Pakayang'aniridwa pafupipafupi komanso kutsimikizira tsiku ndi tsiku, ma gauge a ceramic amawonetsa kusuntha kochepa, zomwe zikutanthauza kuti nthawi zambiri pamakhala kuwonjezereka kwa kayendedwe ka calibration. Pa mizere yopanga ya semiconductor yomwe ikufuna kugwira ntchito bwino kwambiri, izi sizitanthauza kudalirika kwambiri pakuyeza komanso kuchepetsa ndalama zogwiritsidwa ntchito kwa nthawi yayitali.
Kukhazikika kwa Kutentha: Chothandizira Kusinthasintha kwa Kutentha kwa Malo Ozungulira
Mu metrology ya semiconductor, kutentha ndi chimodzi mwa zinthu zazikulu zomwe zimakhudza kulondola kwa muyeso. Ngakhale kusinthasintha pang'ono kwa kutentha kwa mlengalenga kungayambitse kufutukuka kwa kutentha ndi kufupika kwa zinthu zachitsulo, zomwe zimapangitsa zolakwika zosafunikira pakuyeza. Zipangizo za ceramic, makamaka ziwiya za alumina zoyera kwambiri, zimakhala ndi coefficient yotsika kwambiri ya kufutukuka kwa kutentha.
Kukhazikika kwa kutentha kumeneku kumalola ma gauge a ceramic kukhalabe ogwirizana kwambiri mu miyeso yowunikira ngakhale kutentha kwa malo ozungulira kukusintha—mwachitsanzo, panthawi yosintha kapena chifukwa cha kusintha kwa kutentha kwa m'deralo popanga. Pamene ma gauge achitsulo akusintha chifukwa cha kutentha kwa manja kapena kusintha kwa kutentha kwa chipinda, ma gauge a ceramic amakhalabe olimba. Khalidweli ndilofunika kwambiri pakuwunika kwa semiconductor komwe kumafuna kutsimikizira kwa nthawi yayitali kwa zida, kuyerekezera koyerekeza, ndi malo oyika zida. Kumaonetsetsa kuti kuyerekezera kwa muyeso kumakhalabe kofanana kaya mu labu yoyang'aniridwa ndi kutentha kapena pansi pa shopu yokhala ndi kusinthasintha kwakukulu, motero kumathetsa kutumiza zolakwika zomwe zimachitika chifukwa cha kusintha kwa kutentha komwe kumachokera.
Ukhondo ndi Kukana Kudzimbiritsa: Kusinthana ndi Malo Ochitira Zinthu Mopitirira Muyeso
Kupanga ma semiconductor kumaphatikizapo kugwiritsa ntchito kwambiri mpweya wa mankhwala ndi njira za plasma, zomwe zimapangitsa kuti pakhale zovuta kwambiri pa kukhazikika kwa mankhwala a ma gauge. Mu njira monga etching ndi thin-film deposition, ma gauge wamba achitsulo kapena pulasitiki amawonongeka mosavuta ndi mpweya wowononga, zomwe zimapangitsa kuti pakhale kuipitsidwa kwa tinthu tating'onoting'ono. Zipangizo zadothi zoyera kwambiri (monga alumina kapena silicon nitride yokhala ndi chiyero choposa 99.6%) zimawonetsa kukana kwa mankhwala a dzimbiri, zomwe zimatha kupirira mpweya wochokera ku halogen ndi malo okhala acidic/alkaline.
Kuphatikiza apo, makampani opanga ma semiconductor amalamulira kwambiri kuipitsidwa kwa tinthu tating'onoting'ono. Ma gauge a ceramic, omwe pamwamba pake amakhala osalala komanso olondola, sachedwa kutaya tinthu tating'onoting'ono. Pakasamutsidwa ndi kuyang'aniridwa, kugwiritsa ntchito zida za ceramic, makapu okoka, kapena kupeza ma pini kumateteza fumbi kuti lisakokeredwe ndi chitsulo. Khalidwe la "loyera m'chipinda choyera" limapangitsa kuti ma gauge a ceramic asakhale chida choyezera chokha komanso choteteza kusunga miyezo ya chilengedwe m'chipinda choyera. Makamaka pazida zazikulu monga makina ojambulira ndi zoyika ma ion, kugwiritsa ntchito zida za ceramic kumaonetsetsa kuti chipinda chogwirira ntchitocho sichinaipitsidwe ndi chitsulo, motero kuteteza kuchuluka kwa ma chip.
Kupanga ndi Kukhazikitsa Zinthu Molondola: Kufunafuna Ulemu Kuyambira pa Zinthu Zofunika Kupita ku Zinthu Zomalizidwa
Kusintha ubwino wa zipangizo zadothi kukhala zenizeni zoyezera sikungasiyanitsidwe ndi njira zopangira molondola. Kupanga ma gauge a ceramic a semiconductor-grade ndi ntchito yokonzedwa bwino, yomwe imafuna kuwongolera mosamala pa sitepe iliyonse kuyambira kukonzekera ufa ndi kukanikiza kwa isostatic mpaka kukanikiza kutentha kwambiri. Mwachitsanzo, kuti zitsimikizire kuti pali kufanana kwa miyeso, kupotoka kwa kutentha kwa sintering kuyenera kulamulidwa bwino; kupotoka kulikonse kwa mphindi kungayambitse kupsinjika kwamkati kosagwirizana, zomwe pambuyo pake zimakhudza kukhazikika kwa miyeso kwa nthawi yayitali.
Pomaliza, kugwiritsa ntchito malo opangira makina a 5-axis pamodzi ndi zida zokutidwa ndi diamondi kumalola kuti kulondola kwa makina a ceramic gauges kulamuliridwe pamlingo wa sub-micron. Makina olondola kwambiri awa amawonekera osati kokha mu kulekerera kwa miyeso komanso mu kuwongolera kusakhazikika kwa pamwamba. Malo oyezera osalala samangochepetsa kuwonongeka komanso amaonetsetsa kuti mphamvu yolumikizirana imayenda bwino panthawi yoyezera. Pakadali pano, makampaniwa akhazikitsa machitidwe olimba, monga ISO 3650, omwe amawongolera magiredi olondola (monga, K, 0, 00) a ceramic gauges, kuonetsetsa kuti akukwaniritsa zosowa zonse za zida za semiconductor kuyambira pa macro assembly mpaka micro inspection.
Mapeto Ogwiritsira Ntchito: Kupanga Zachilengedwe Zoyezera Molondola Kwambiri
Pamene ukadaulo wa semiconductor ukupita patsogolo kwambiri kupita ku ma node apamwamba kwambiri, kufunikira kwa kulondola kwa muyeso sikudzatha. Zochitika zogwiritsira ntchito ma gauge a ceramic zikukulirakulira nthawi zonse, zikusintha kuchokera ku ma gauge blocks achikhalidwe ndi ma ring gauge kupita ku zigawo zovuta za kapangidwe kake, monga mbale zogawa gasi, mphete zoyang'ana, ndi ma chuck a electrostatic. Mu kuyesa kwa khadi la probe, ma substrates a ceramic a silicon nitride, omwe ali ndi kutentha kwawo kwapamwamba komanso kutchinjiriza kwamagetsi, akhala zigawo zazikulu zomwe zimanyamula ma probe masauzande ambiri kuti ayesere kwambiri. Mu magawo a makina a lithography, ma ceramic a silicon carbide, chifukwa cha kupepuka kwawo komanso kulimba kwawo kwakukulu, akhala zida zofunika kwambiri kuti akwaniritse kuyenda kolondola kwambiri kwa nanometer.
Mwachidule, kugwiritsa ntchito ma ceramic gauges mumakampani opanga ma semiconductor sikungosintha zinthu koma kusintha kwa kulondola. Mwa kuchotsa zinthu zosokoneza monga dzimbiri, maginito, kufalikira kwa kutentha, ndi dzimbiri la mankhwala, ma ceramic gauges amapanga njira yokhazikika komanso yodalirika yoyezera kupanga ma semiconductor. M'tsogolomu, ndi kupita patsogolo kwa sayansi ya zinthu ndi ukadaulo wokonza, ma ceramic gauges apitilizabe kuchita gawo lalikulu mdziko la microscopic, kuthandiza makampani opanga ma semiconductor kufunafuna kwawo kosalekeza kulondola komaliza.
