Silane (SiH4)

Technical Parameters

Silane yog qhov sib xyaw ntawm silicon thiab hydrogen.Nws yog ib lub ntsiab lus dav dav rau cov khoom sib txuas, suav nrog monosilane (SiH4), disilane (Si2H6) thiab qee cov qib siab dua silicon-hydrogen compounds.Ntawm lawv, monosilane yog feem ntau, qee zaum hu ua silane luv luv.Silane yog cov roj tsis muaj xim uas muaj ntxhiab tsw ntxhiab ntawm qej.Soluble nyob rau hauv dej, yuav luag insoluble nyob rau hauv ethanol, ether, benzene, chloroform, silicon chloroform thiab silicon tetrachloride.Cov khoom siv tshuaj lom neeg ntawm silanes muaj zog ntau dua li alkanes thiab yooj yim oxidized.Spontaneous combustion tuaj yeem tshwm sim thaum sib cuag nrog huab cua.Nws tsis hnov ​​​​mob nrog nitrogen hauv qab 25 ° C, thiab tsis hnov ​​​​mob nrog hydrocarbon tebchaw ntawm chav tsev kub.Hluav taws thiab tawg ntawm silane yog tshwm sim los ntawm cov tshuaj tiv thaiv nrog oxygen.Silane yog rhiab heev rau oxygen thiab huab cua.Silane nrog rau qee qhov concentration tseem yuav hnov ​​​​mob nrog oxygen ntawm qhov kub ntawm -180 ° C.Silane tau dhau los ua cov pa roj tshwj xeeb tshaj plaws uas siv rau hauv cov txheej txheem semiconductor microelectronics, thiab siv rau hauv kev npaj ntawm ntau yam microelectronic films, xws li ib leeg siv lead ua zaj duab xis, microcrystalline, polycrystalline, silicon oxide, silicon nitride, thiab hlau silicides.Cov ntawv thov microelectronic ntawm silane tseem tab tom tsim nyob rau hauv qhov tob: qis-kub epitaxy, xaiv epitaxy, thiab heteroepitaxial epitaxy.Tsis yog rau cov khoom siv silicon thiab silicon integrated circuits, tab sis kuj rau cov khoom siv semiconductor (gallium arsenide, silicon carbide, thiab lwm yam).Nws kuj muaj cov ntawv thov hauv kev npaj cov khoom siv superlattice quantum zoo.Nws tuaj yeem hais tau tias silane yog siv nyob rau hauv yuav luag tag nrho cov kev sib txuas ua ke ntawm cov kab ntau lawm nyob rau niaj hnub no.Daim ntawv thov ntawm silane ua silicon-muaj zaj duab xis thiab txheej tau nthuav dav los ntawm cov tsoos microelectronics kev lag luam mus rau ntau yam xws li steel, machinery, tshuaj thiab optics.Lwm lub peev xwm ntawm silane yog kev tsim cov khoom siv hluav taws xob ua haujlwm siab, tshwj xeeb tshaj yog kev siv silane los tsim silicide (Si3N4, SiC, thiab lwm yam) micropowder technology tau nyiam ntau thiab ntau dua.

Daim ntawv thov:

① Hluav taws xob:

Silane yog siv rau polycrystalline silicon txheej ntawm silicon wafers thaum tsim khoom semiconductors, thiab sealants.

② Hnub ci:

Silane yog siv nyob rau hauv hnub ci photovoltaic module manufacturing.

③ Kev lag luam:

Nws yog siv nyob rau hauv Energy-saving Green Glass thiab siv rau vapor deposition nyias zaj duab xis txheej txheem.

Cov pob li qub:

Qhov zoo:

① Ntau tshaj kaum xyoo ntawm kev ua lag luam;

② ISO daim ntawv pov thawj chaw tsim khoom;
