I-Silane (SiH4)

Iiparamitha zobuGcisa

ISilane yikhompawundi yesilicon kunye nehydrogen. Ligama eliqhelekileyo loluhlu lwee-compounds, kubandakanywa i-monosilane (SiH4), i-disilane (i-Si2H6) kunye nezinye i-silicon-hydrogen compounds eziphezulu. Phakathi kwabo, i-monosilane yeyona nto ixhaphakileyo, ngamanye amaxesha ibizwa ngokuba yi-silane ngokufutshane. ISilane yigesi engenambala nevumba elizotheyo legalikhi. Inyibilika emanzini, phantse ayinyibiliki kwi-ethanol, ether, benzene, chloroform, silicon chloroform kunye nesilicon tetrachloride. Iimpawu zeekhemikhali ze-silane zisebenza ngakumbi kune-alkanes kwaye zixutywe ngokulula. Ukutshisa okuzenzekelayo kunokwenzeka xa udibana nomoya. Ayisebenzi kunye ne-nitrogen engaphantsi kwe-25 ° C, kwaye ayisebenzi kunye ne-hydrocarbon compounds kwiqondo lokushisa. Umlilo kunye nogqabhuko-dubulo lwe-silane zisiphumo sokusabela kweoksijini. ISilane inochuku kakhulu kwioksijini nomoya. ISilane enogxininiso oluthile nayo iya kugqabhuka ngeoksijini kubushushu obuyi-180°C. I-Silane iye yaba yeyona rhasi ibaluleke kakhulu esetyenziswa kwiinkqubo ze-semiconductor microelectronics, kwaye isetyenziswa ekulungiseleleni iifilimu ezahlukeneyo ze-microelectronic, kubandakanywa neefilimu zekristale enye, i-microcrystalline, i-polycrystalline, i-silicon oxide, i-silicon nitride, kunye ne-silicidi zetsimbi. Ukusetyenziswa kwe-microelectronic ye-silane zisakhula ngobunzulu: i-epitaxy ephantsi yobushushu, i-epitaxy ekhethiweyo, kunye ne-heteroepitaxial epitaxy. Akunjalo kuphela kwizixhobo ze-silicon kunye neesekethe ezidibeneyo ze-silicon, kodwa kunye nezixhobo ezidibeneyo ze-semiconductor (i-gallium arsenide, i-silicon carbide, njl.). Ikwanayo nezicelo ekulungiseleleni izixhobo ze-superlattice quantum kakuhle. Kunokuthiwa i-silane isetyenziswa phantse kuyo yonke imigca yemveliso yesekethe edibeneyo ephambili kumaxesha anamhlanje. Ukusetyenziswa kwe-silane njengefilimu equlethe i-silicon kunye nokwaleka kuye kwanda ukusuka kwishishini lemveli le-microelectronics ukuya kwiinkalo ezahlukeneyo ezifana nentsimbi, oomatshini, iikhemikhali kunye ne-optics. Olunye usetyenziso olunokubakho lwe-silane kukwenziwa kweendawo eziphezulu ze-injini ye-ceramic, ngakumbi ukusetyenziswa kwe-silane ukwenza i-silicide (i-Si3N4, i-SiC, njl.) ubuchwepheshe be-micropowder buye batsala ingqalelo ngakumbi nangakumbi.

Isicelo:

① Ngombane:

ISilane isetyenziswa kumaleko e-polycrystalline silicon kwiiwafer zesilicon xa kusenziwa iisemiconductors, kunye nezitywini.

②Ilanga:

I-Silane isetyenziselwa ukuveliswa kwemodyuli ye-solar photovoltaic.

③Amashishini:

Isetyenziswa kwiGlasi eluhlaza egcina Amandla kwaye ifakwe kwinkqubo yokubeka umphunga obhityileyo wefilimu.
