zamagetsimpweya wapaderandi nthambi yofunika kwambiri ya mpweya wapadera. Umalowa pafupifupi ulalo uliwonse wa kupanga ma semiconductor ndipo ndi zinthu zofunika kwambiri popanga mafakitale amagetsi monga ma ultra-large-scale integrated circuits, flat panel display devices, ndi solar cells.

Mu ukadaulo wa semiconductor, mpweya wokhala ndi fluorine umagwiritsidwa ntchito kwambiri. Pakadali pano, pamsika wapadziko lonse wa gasi wamagetsi, mpweya wamagetsi wokhala ndi fluorine umawerengera pafupifupi 30% ya zonse. Mpweya wamagetsi wokhala ndi fluorine ndi gawo lofunikira la mpweya wapadera wamagetsi pazambiri zamagetsi. Amagwiritsidwa ntchito makamaka ngati zotsukira ndi zoyeretsera, ndipo angagwiritsidwenso ntchito ngati zinthu zopangira filimu, ndi zina zotero. M'nkhaniyi, wolembayo akuphunzitsani kumvetsetsa mpweya wamba wokhala ndi fluorine.

Zotsatirazi ndi mpweya wokhala ndi fluorine womwe umagwiritsidwa ntchito kwambiri

Nayitrogeni trifluoride (NF3): Mpweya womwe umagwiritsidwa ntchito poyeretsa ndi kuchotsa zinthu zomwe zawonongeka, nthawi zambiri umagwiritsidwa ntchito poyeretsa zipinda zochitira zinthu ndi malo ogwirira ntchito.

Sulfur hexafluoride (SF6): Chothandizira kupukutira fluorinating chomwe chimagwiritsidwa ntchito poika oxide mu oxide komanso ngati mpweya woteteza kudzaza zinthu zotetezera kutentha.

Hydrogen fluoride (HF): Amagwiritsidwa ntchito kuchotsa ma oxide pamwamba pa silicon komanso ngati chokometsera cha silicon ndi zinthu zina.

Nayitrogeni fluoride (NF): Amagwiritsidwa ntchito kuswa zinthu monga silicon nitride (SiN) ndi aluminium nitride (AlN).

Trifluoromethane (CHF3) nditetrafluoromethane (CF4): Amagwiritsidwa ntchito podula zinthu za fluoride monga silicon fluoride ndi aluminium fluoride.

Komabe, mpweya wokhala ndi fluorine uli ndi zoopsa zina, kuphatikizapo poizoni, kuwonongeka, komanso kuyaka.

Kuopsa kwa poizoni

Mpweya wina wokhala ndi fluorine ndi woopsa, monga hydrogen fluoride (HF), womwe umatulutsa nthunzi umakwiyitsa kwambiri khungu ndi njira yopumira komanso umavulaza thanzi la anthu.

Kuwononga

Hydrogen fluoride ndi ma fluoride ena amawononga kwambiri khungu, maso ndi njira yopumira.

Kuyaka

Ma fluoride ena amatha kuyaka ndipo amachitapo kanthu ndi mpweya kapena madzi mumlengalenga kuti atulutse kutentha kwambiri ndi mpweya woipa, zomwe zingayambitse moto kapena kuphulika.

Ngozi yoopsa kwambiri

Mpweya wina wokhala ndi fluorine umaphulika ukagwiritsidwa ntchito komanso kusungidwa ndipo umafunika chisamaliro chapadera.

Zotsatira pa chilengedwe

Mpweya wokhala ndi fluorine uli ndi nthawi yayitali mumlengalenga komanso GWP, zomwe zimakhudza kwambiri mpweya wa ozoni womwe uli mumlengalenga ndipo zingayambitse kutentha kwa dziko lapansi komanso kuipitsa chilengedwe.

Kugwiritsa ntchito mpweya m'magawo atsopano monga zamagetsi kukupitirirabe kukula, zomwe zikubweretsa kufunikira kwakukulu kwa mpweya wamafakitale. Kutengera kuchuluka kwa mphamvu zatsopano zopangira zida zazikulu zamagetsi monga ma semiconductor ndi ma display panels ku China m'zaka zingapo zikubwerazi, komanso kufunikira kwakukulu kwa kusintha kwa zida zamagetsi zamagetsi, makampani opanga gasi zamagetsi am'nyumba adzayambitsa kukula kwakukulu.
