Kodi carbon tetrafluoride ndi chiyani? ntchito yake ndi chiyani?

Ndi chiyanicarbon tetrafluoride? ntchito yake ndi chiyani?

Mpweya wa tetrafluoride, yomwe imadziwikanso kuti tetrafluoromethane, imatengedwa ngati mankhwala osakhazikika. Imagwiritsidwa ntchito mu plasma etching process ya mabwalo osiyanasiyana ophatikizika, komanso amagwiritsidwa ntchito ngati mpweya wa laser ndi refrigerant. Ndiwokhazikika pansi pa kutentha kwabwino komanso kukakamizidwa, koma ndikofunikira kupewa kukhudzana ndi ma okosijeni amphamvu, zinthu zoyaka kapena zoyaka. Carbon tetrafluoride ndi mpweya wosayaka. Ngati chikakumana ndi kutentha kwakukulu, chidzachititsa kuti mkati mwa chidebecho chiwonjezeke, ndipo pamakhala ngozi yosweka ndi kuphulika. Nthawi zambiri amatha kucheza ndi madzi ammonia-sodium zitsulo reagent kutentha firiji.

Mpweya wa tetrafluoridepakadali pano ndi gasi wamkulu kwambiri wa plasma wogwiritsidwa ntchito m'makampani opanga ma microelectronics. Itha kugwiritsidwa ntchito kwambiri mu etching ya pakachitsulo, pakachitsulo woipa, galasi phosphosilicate ndi zina woonda filimu zipangizo, kuyeretsa pamwamba pa zipangizo zamagetsi, dzuwa kupanga selo, laser luso, mpweya gawo kutchinjiriza, otsika kutentha firiji, wothandizila kutayikira kudziwika, ndi zotsukira pakupanga dera losindikizidwa zimakhala ndi ntchito zambiri.
