Mipweya ya Ultra-high purity (UHP) ndiye moyo wamakampani opanga ma semiconductor. Monga kufunikira kosaneneka komanso kusokoneza kwamakampani ogulitsa padziko lonse lapansi kukukweza mtengo wamafuta oponderezedwa kwambiri, mapangidwe atsopano a semiconductor ndi machitidwe opanga akuwonjezera kuchuluka kwa kuwononga kofunikira. Kwa opanga ma semiconductor, kukwanitsa kuwonetsetsa chiyero cha mpweya wa UHP ndikofunikira kwambiri kuposa kale.

Magesi a Ultra High Purity (UHP) Ndiwovuta Kwambiri Pakupanga Zamakono Zamakono Zopangira Semiconductor

Chimodzi mwazinthu zazikulu zomwe zimagwiritsidwa ntchito ndi mpweya wa UHP ndikulowetsa: UHP mpweya umagwiritsidwa ntchito popereka mpweya wotetezera kuzungulira zigawo za semiconductor, potero zimawateteza ku zotsatira zovulaza za chinyezi, mpweya ndi zonyansa zina mumlengalenga. Komabe, inertization ndi imodzi mwazinthu zosiyanasiyana zomwe mpweya umachita mumakampani a semiconductor. Kuchokera pamipweya yoyambira ya plasma kupita ku mipweya yokhazikika yomwe imagwiritsidwa ntchito polumikizira ndi kutsekereza, mipweya yothamanga kwambiri imagwiritsidwa ntchito pazifukwa zosiyanasiyana ndipo ndiyofunikira pamayendedwe onse a semiconductor.

Ena mwa mpweya "pachimake" mu makampani semiconductor monganayitrogeni(omwe amagwiritsidwa ntchito ngati kuyeretsa wamba ndi gasi wopanda pake),argon(omwe amagwiritsidwa ntchito ngati gasi woyambira wa plasma pakuwongolera ndi kuyika),helium(omwe amagwiritsidwa ntchito ngati gasi wopanda mpweya wokhala ndi zida zapadera zosinthira kutentha) ndihaidrojeni(amasewera magawo angapo pakuwongolera, kuyika, epitaxy ndi kuyeretsa plasma).

Monga ukadaulo wa semiconductor wasintha ndikusintha, momwemonso mpweya womwe umagwiritsidwa ntchito popanga. Masiku ano, mafakitale opanga semiconductor amagwiritsa ntchito mpweya wambiri, kuchokera ku mpweya wabwino mongakryptonindineonku mitundu yogwira ntchito monga nitrogen trifluoride (NF 3) ndi tungsten hexafluoride (WF 6).

Kukula kufunikira kwa chiyero

Chiyambireni kupangidwa kwa microchip yoyamba yogulitsa malonda, dziko lapansi lawona kuwonjezeka kodabwitsa komwe kumayandikira kwambiri magwiridwe antchito a zida za semiconductor. Pazaka zisanu zapitazi, imodzi mwa njira zotsimikizika zokwaniritsira kuwongolera kotereku kwakhala "kukulitsa kukula": kuchepetsa miyeso yayikulu yamamangidwe a chip omwe alipo kuti afinyire ma transistors ambiri pamalo omwe aperekedwa. Kuphatikiza pa izi, chitukuko cha zomangamanga zatsopano za chip ndi kugwiritsa ntchito zipangizo zamakono zapanga kudumpha pakuchita kwa chipangizo.

Masiku ano, miyeso yovuta ya semiconductors yocheperako tsopano ndiyocheperako kotero kuti kukula sikulinso njira yabwino yopititsira patsogolo magwiridwe antchito a chipangizocho. M'malo mwake, ofufuza a semiconductor akuyang'ana mayankho mwazinthu zatsopano komanso zomangamanga za 3D chip.

Zaka makumi angapo za kukonzanso mosatopa kumatanthauza kuti zida zamakono za semiconductor ndi zamphamvu kwambiri kuposa ma microchips akale - koma ndizosalimba kwambiri. Kubwera kwaukadaulo wopanga ma 300mm wafer kwawonjezera mulingo wowongolera zonyansa zomwe zimafunikira pakupanga semiconductor. Ngakhale kuipitsidwa pang'ono pakupanga (makamaka osowa kwambiri kapena mpweya wa inert) kungayambitse kuwonongeka kwa zida - kotero kuyera kwa gasi tsopano kuli kofunika kwambiri kuposa kale lonse.

Pafakitale yopangira zida za semiconductor, gasi wokwera kwambiri ndiye kale wowononga ndalama zambiri pambuyo pa silicon yokha. Mitengoyi ikuyembekezeka kukwera pomwe kufunikira kwa ma semiconductors kumakwera kwambiri. Zomwe zikuchitika ku Europe zadzetsa kusokonezeka kwa msika wamagesi wachilengedwe wovuta kwambiri. Ukraine ndi mmodzi wa mayiko otumiza kunja mkulu-chiyeroneonzizindikiro; Kuwukira kwa Russia kukutanthauza kuti gasi wosowawo akucheperachepera. Izi zinapangitsa kuti pakhale kusowa komanso kukwera mtengo kwa mpweya wina wabwino mongakryptonindixenon.
