Kukhazikika kwa Alumina Ceramic mu Kupanga Semiconductor: Zaka 10 za Kukhazikika Kosayerekezeka

Mu makampani opanga zinthu za semiconductor, komwe micron imodzi ingakhale kusiyana pakati pa gulu lolemera kwambiri ndi kulephera kokwera mtengo, kusankha zinthu zoyezera n'kofunika kwambiri. Pamene kuyang'anira ma lithography ndi wafer kukukankhira malire a fizikisi, zitsulo zachikhalidwe komanso granite yapamwamba zikufikira malire awo.

Alumina Ceramic (Al2O3) yakhala njira yabwino kwambiri kwa opanga zida za semiconductor. Popeza kuti zipangizo za semiconductor zimatha kusunga zinthu zakale kwa zaka zoposa 10, sizilinso zapamwamba—ndizofunikira kwambiri pakupanga zinthu.

Chifukwa Chiyani Alumina Ceramic Yabwino Kwambiri?

Musanayambe kugwiritsa ntchito, ndikofunikira kumvetsetsa mbiri yapadera ya "ziwopsezo zitatu" za nkhaniyi:

• Kukhazikika kwa Kutentha: Kuchuluka kwa kutentha komwe kumawonjezeka pang'ono (≈7 × 10^{-6}/K) kumatsimikizira kuti miyezo imakhalabe yofanana ngakhale kutentha komwe kumapangidwa ndi zida zothamanga kwambiri.

• Yopanda Magnetic & Non-Conductive: Yofunika kwambiri pa malo osungira mpweya ndi lithography ya electron-beam yomwe imakhudza maginito.

• Kupanda Dzimbiri: Mosiyana ndi chitsulo, zoumba zadothi sizimapangidwa ndi mankhwala, zomwe zimapangitsa kuti zigwirizane ndi njira zoyeretsera zipinda zoyera komanso malo osungira mpweya wowononga.

Ntchito 5 Zofunikira mu Zida za Semiconductor

1. Magawo a Makina Ojambulira Ma Lithography

Photolithography yamakono imafuna malo oimikapo zinthu molingana ndi nanometer. Ma ceramic squares ndi zinthu zina zomangira zimakhala ngati "chisonyezero chachikulu" cha gawo la wafer. Chiŵerengero chawo cha kuuma kwa kulemera chimalola kuti zinthu ziziyenda mofulumira popanda kugwedezeka kapena "kulira" kogwirizana ndi zinthu zolemera.

2. Kuyang'anira Ma Wafer & Metrology

Mu makina a geometry a wafer, Ceramic Master Squares imagwiritsidwa ntchito kulinganiza kupingasa ndi kulunjika kwa ma scanning axes. Popeza ceramic imasunga mawonekedwe ake kwa zaka khumi, makina awa amafunikira nthawi zochepa zokonzanso, zomwe zimapangitsa kuti ntchitoyo igwire bwino ntchito.

3. Kusonkhanitsa Molondola kwa Zipinda Zosapanga Chinyezi

Kusonkhanitsa ma semiconductor nthawi zambiri kumachitika m'malo osungira mpweya pomwe mafuta ndi ochepa. Ma gage a ceramic amapereka chizindikiro "chouma" chomwe sichingachotse mpweya kapena kuipitsa mpweya, ndikuwonetsetsa kuti zigawo zamkati zikugwirizana ndi kulekerera kwa sub-micron.

4. Kuyesa Kwamagetsi Kwapafupipafupi Kwambiri

Pa kuyesa kwa chip mwachangu kwambiri, kusokoneza kulikonse kwa maginito kapena kuwongolera kwa chida choyezera kungasokoneze zotsatira. Chifukwa cha kusagwiritsa ntchito maginito kwa alumina ceramic, imapangitsa kuti ikhale chinthu choyenera kwambiri chogwiritsira ntchito makadi a probe ndi ma geji olumikizirana.

5. Cleanroom Calibration Masters

Mu zipinda zotsukira za ISO Class 1, dzimbiri ndi chinthu choletsedwa. Ma geji achitsulo amafuna mafilimu amafuta kuti apewe kukhuthala, zomwe ndi chiopsezo chachikulu cha kuipitsidwa. Ma geji a ceramic safuna mafuta ndipo amatha kutsukidwa ndi isopropyl alcohol, kusunga mawonekedwe a "zero-tinthu" kwa zaka zoposa 10.

"Ubwino wa Zaka 10"

Ngakhale kuti ma geji achitsulo amatha kupindika kapena kutha patatha zaka zingapo akugwiritsidwa ntchito kwambiri, kapangidwe ka molekyulu ya Alumina yoyera kwambiri ndi kokhazikika kwambiri. Ikagwiritsidwa ntchito ngati Ceramic Square kapena Straight Edge, kuuma kwa chinthucho (kuyandikira kwa safiro) kumalepheretsa kuwonongeka kwa pamwamba pa microscopic komwe nthawi zambiri kumapangitsa kuti kulondola "kusunthike" pakapita nthawi.

Kwa OEM ya semiconductor, izi zikutanthauza kuchepetsedwa ka 10 kwa ndalama zosamalira kwa nthawi yayitali komanso kuchuluka kwa chidaliro mu kulondola kwa moyo wonse wa makinawo.
