Magasi eUHP (Ultra-high purity) ndiwo musimboti weindasitiri yemasemiconductor. Sezvo kudiwa kusati kwamboitika uye kukanganiswa kwecheni dzepasi rose zvichikwidza mutengo wegasi repamusoro-soro, dhizaini itsva yemasemiconductor uye maitiro ekugadzira ari kuwedzera mwero wekudzora kusvibiswa kunodiwa. Kune vagadziri vemasemiconductor, kukwanisa kuve nechokwadi chekuti gasi reUHP rakachena kwakakosha kupfuura kare.

Magasi eUHP (Ultra High Purity) Akakosha Zvikuru Mukugadzirwa KwemaSemiconductor Emazuva Ano

Imwe yenzira huru yekushandisa gasi reUHP ndeyekusanganisa zvinhu: gasi reUHP rinoshandiswa kupa mhepo inodzivirira zvikamu zve semiconductor, nokudaro richizvidzivirira kubva kumigumisiro inokuvadza yehunyoro, okisijeni nezvimwe zvinosvibisa mumhepo. Zvisinei, kusanganisa zvinhu ndeimwe yemabasa akasiyana-siyana anoitwa nemagasi muindasitiri ye semiconductor. Kubva kumagasi ekutanga eplasma kusvika kumagasi anoshandiswa mukucheka nekuwedzera, magasi ane pressure yakanyanya anoshandiswa pazvinangwa zvakasiyana-siyana uye akakosha muchikamu chose che semiconductor supply chain.

Mamwe emagasi "akakosha" muindasitiri yesemiconductor anosanganisiranitrogen(inoshandiswa semushonga wekuchenesa uye gasi risina simba),argon(inoshandiswa segasi guru replasma mukuita etching uye deposition reactions),heliyamu(inoshandiswa segasi risingapindi mvura rine hunhu hwakakosha hwekutamisa kupisa) uyehaidrojeni(anoita mabasa akawanda mukuchenesa, kuisa masero mumasero, epitaxy uye kuchenesa plasma).

Sezvo tekinoroji ye semiconductor yakashanduka uye yakachinja, magasi anoshandiswa mukugadzirwa kwawo ashandukawo. Nhasi, mafekitori ekugadzira semiconductor anoshandisa magasi akasiyana-siyana, kubva kumagasi akanaka akadai sekryptonuyeneonkumarudzi anochinja-chinja akadai senitrogen trifluoride (NF3) uye tungsten hexafluoride (WF6).

Kudiwa kuri kukura kwekuchena

Kubva pakagadzirwa microchip yekutanga yekutengeserana, nyika yakaona kuwedzera kunoshamisa kwekushanda kwemidziyo ye semiconductor. Mumakore mashanu apfuura, imwe yenzira dzakasimba dzekuvandudza mashandiro emhando iyi yave iri kuburikidza ne "kukura saizi": kuderedza zviyero zvakakosha zvemachip architecture aripo kuitira kuti ma transistors akawanda asvine munzvimbo yakatarwa. Pamusoro peizvi, kugadzirwa kwemachip architecture matsva uye kushandiswa kwezvinhu zvemazuva ano kwakaburitsa shanduko huru mukushanda kwemidziyo.

Nhasi uno, zvinhu zvakakosha zvema semiconductors epamusoro-soro zvava zvidiki zvekuti kukura kwehukuru hakusisiri nzira inoshanda yekuvandudza mashandiro emuchina. Pane kudaro, vaongorori vema semiconductor vari kutsvaga mhinduro muchimiro chezvinhu zvitsva uye mapurani e3D chip.

Makumi emakore ekugadzirwa patsva kusinganeti zvinoreva kuti michina yemazuva ano ine simba guru kupfuura microchips dzekare - asi zvakare haina kusimba. Kuuya kwetekinoroji yekugadzira wafer ye300mm kwakawedzera mwero wekudzora kusvibiswa kunodiwa pakugadzira semiconductor. Kunyangwe kusvibiswa kudiki diki mukugadzirwa (kunyanya magasi asingawanzoonekwi kana asina kusimba) kunogona kutungamira kukundikana kwemidziyo - saka kuchena kwegasi kwave kukosha kupfuura kare.

Kune fekitori inogadzira ma semiconductor, gasi re ultra-high-purity ndiro rinodhura zvakanyanya mushure me silicon pachayo. Mitengo iyi inotarisirwa kuwedzera sezvo kudiwa kwema semiconductors kuchikwira zvakanyanya. Zviitiko muEurope zvakakonzera kukanganiswa kwakanyanya kumusika wegesi rechisikigo une pressure yakanyanya. Ukraine ndeimwe yevatengesi vakuru vepasi rose vanoburitsa gasi re ultra-high-purity.neonzviratidzo; kupinda kweRussia mugungwa zvinoreva kuti gasi risingawanzo kuwanikwa riri kudziviswa. Izvi zvakakonzera kushomeka kwegasi uye mitengo yemamwe magasi akanaka akadai sekryptonuyexenon.
