I-Silane (SiH4)

Imingcele Yezobuchwepheshe

I-Silane iyinhlanganisela ye-silicon ne-hydrogen. Kuyitemu evamile yochungechunge lwezinhlanganisela, okuhlanganisa i-monosilane (SiH4), i-disilane (Si2H6) nezinye izinhlanganisela zezinga eliphezulu le-silicon-hydrogen. Phakathi kwazo, i-monosilane iyona evame kakhulu, ngezinye izikhathi ebizwa ngokuthi i-silane ngamafuphi. I-Silane iyigesi engenambala enephunga elinyanyekayo likagalikhi. Incibilika emanzini, cishe ayincibiliki ku-ethanol, ether, benzene, chloroform, silicon chloroform ne-silicon tetrachloride. Amakhemikhali e-silane asebenza kakhulu kunama-alkanes futhi afakwa i-oxidized kalula. Ukusha okuzenzakalelayo kungenzeka lapho uthintana nomoya. Ayisabeli nge-nitrogen engaphansi kuka-25°C, futhi ayisabelani nezinhlanganisela ze-hydrocarbon endaweni yokushisa. Umlilo nokuqhuma kwe-silane kuwumphumela wokusabela komoyampilo. I-Silane izwela kakhulu emoyeni nasemoyeni. I-Silane ene-concentration ethile nayo izosabela ngokuqhuma ne-oxygen ezingeni lokushisa elingu-180°C. I-Silane isiphenduke igesi ekhethekile ebaluleke kakhulu esetshenziswa ezinqubweni ze-semiconductor microelectronics, futhi isetshenziswa ekulungiseleleni amafilimu e-microelectronic ahlukahlukene, okuhlanganisa amafilimu ekristalu eyodwa, i-microcrystalline, i-polycrystalline, i-silicon oxide, i-silicon nitride, kanye nezinsimbi zensimbi. Ukusetshenziswa kwe-microelectronic ye-silane zisathuthuka ngokujulile: i-epitaxy yezinga lokushisa eliphansi, i-epitaxy ekhethiwe, ne-heteroepitaxial epitaxy. Hhayi kuphela kumadivayisi we-silicon namasekethe ahlanganisiwe we-silicon, kodwa futhi namadivayisi ahlanganisiwe we-semiconductor (i-gallium arsenide, i-silicon carbide, njll.). Iphinde ibe nezinhlelo zokusebenza ekulungiseleleni izinto zokwakha ze-superlattice quantum. Kungashiwo ukuthi i-silane isetshenziswa cishe kuyo yonke imigqa yokukhiqiza yesifunda edidiyelwe ezikhathini zanamuhla. Ukusetshenziswa kwe-silane njengefilimu equkethe i-silicon nokunamathela kuye kwanda kusukela embonini evamile ye-microelectronics kuya emikhakheni ehlukahlukene efana nensimbi, imishini, amakhemikhali kanye ne-optics. Okunye okungase kusetshenziswe i-silane ukwakhiwa kwezingxenye zenjini ye-ceramic esebenza kahle kakhulu, ikakhulukazi ukusetshenziswa kwe-silane ukwenza i-silicide (Si3N4, SiC, njll.) ubuchwepheshe be-micropowder budonse ukunakwa okwengeziwe.

Isicelo:

① electronic:

I-Silane isetshenziselwa izendlalelo ze-polycrystalline silicon kuma-wafers we-silicon lapho kukhiqizwa ama-semiconductors, nama-sealants.

②Solar:

I-Silane isetshenziswa ekukhiqizeni i-solar photovoltaic module.

③Okwezimboni:

Isetshenziswa Engilazini Eluhlaza Eyonga Amandla futhi isetshenziswa enqubweni yefilimu encane yokubeka umhwamuko.

Iphakheji evamile:

Inzuzo:

① Ngaphezu kweminyaka eyishumi emakethe;

②ISO umenzi wesitifiketi;

③Ukulethwa okusheshayo;

④Umthombo wezinto ezingavuthiwe ozinzile;

⑤Isistimu yokuhlaziya eku-inthanethi yokulawula ikhwalithi kuso sonke isinyathelo;

⑥Isidingo esiphezulu kanye nenqubo yokucophelela yokuphatha isilinda ngaphambi kokugcwalisa;

⑦ Ubumsulwa: ukuhlanzeka okuphezulu kwebanga le-elekthronikhi;

⑧ Ukusetshenziswa: izinto zamaseli elanga; ukwenza ukuhlanzeka okuphezulu kwe-polysilicon, i-silicon oxide ne-fiber optical; ukukhiqiza ingilazi enemibala.
