Sulfur Hexafluoride SF6 Gas Semiconductor

Sulfur Hexafluoride SF6 Gas yog cov roj hluavtaws, tsis muaj ntxhiab tsw uas siv hauv kev lag luam hluav taws xob kom cov tes hauj lwm khiav nyab xeeb thiab ntseeg tau. Nws ruaj khov heev, tsis yog - tshuaj lom, tsis yog -flammable thiab electronegative, uas txhais tau tias nws yuav tsis tsim lwm cov tebchaw uas yuav hloov nws lub xeev thiab kev ua tau zoo.

 

SF6 roj yog ib qho ntawm feem ntau siv fluoride gases hauv semiconductor qhuav etching. Nws yog tus cwj pwm los ntawm kev xaiv siab thiab muaj zog etching tus nqi. Nws yog tsim rau etching ntawm tsawg dielectric tas li cov ntaub ntawv xws li silicon oxide, silicon fluoride, silicon nitride, thiab lwm yam.

 

CAS Nr .: 2551-62-4

Cov tshuaj sulfur hexafluoride yog SF₆thiab nws cov molar loj yog 146.00554 g mol^-1. Cov qauv ntawm sulfur hexafluoride yog octahedron, nrog 6 fluorine atoms khi rau hauv nruab nrab sulfur atom. Txhua S-F daim ntawv cog lus muaj lub kaum sab xis 90º. Nws cov qauv tshuaj muaj peev xwm sau tau raws li hauv qab no, nyob rau hauv cov lus sawv cev siv rau cov organic molecules.

 Sulfur hexafluoride (SF6) plasmas feem ntau yog siv rau hauv qhov sib sib zog nqus etching ntawm silicon (Si), silicon oxide (SiO2) thiab tsis ntev los no silica iav.

 Sulfur hexafluoride yog ib qho inorganic compound. Nws yog xim tsis muaj xim, tsis muaj ntxhiab tsw, tsis yog - tshuaj lom, tsis yog - cov pa hluav taws xob ruaj khov ntawm qhov kub thiab txias. Nws yog ib tiam tshiab ntawm ultra-high voltage insulating dielectric khoom. Raws li ib tug zoo roj insulator, nws yog tsuas yog siv rau arc extinguishing nyob rau hauv siab -voltage switches, thiab raws li ib tug insulating cov ntaub ntawv nyob rau hauv loj - muaj peev xwm transformers thiab siab -voltage cables. Feem ntau hloov cov roj foob hluav taws xob (OCBs) uas tuaj yeem muaj cov teeb meem PCBs.

 Sulfur hexafluoride yog cov tracer gas siv nyob rau hauv thawj txoj kev huab cua dispersion modelcalibration, nws tau siv tau zoo raws li ib tug tracer nyob rau hauv oceanography los kawm diapycnalmixing thiab huab cua - sea gas exchange.

Xiamen Juda Chemical & Equipment CO., LTD tsim nyob rau xyoo 2004, yog tus kws tshaj lij kev lag luam koom nrog kev lag luam gases, tshwj xeeb gases, hluav taws xob gases, Mixture gases. Peb nyob hauv Xiamen nrog kev thauj mus los yooj yim. Kev mob siab rau kev tswj hwm nruj thiab kev xav zoo rau cov neeg siv khoom, peb cov neeg ua haujlwm paub txog ib txwm muaj los tham txog koj cov kev xav tau thiab ua kom cov neeg siv khoom txaus siab.
