I-Silaneiyinhlanganisela ye-silicon ne-hydrogen, futhi yigama elijwayelekile lochungechunge lwama-compound. I-Silane ihlanganisa kakhulu i-monosilane (SiH4), i-disilane (Si2H6) kanye namanye ama-compound e-silicon hydrogen asezingeni eliphezulu, kanye nefomula ejwayelekile i-SinH2n+2. Kodwa-ke, ekukhiqizweni kwangempela, ngokuvamile sibhekisela ku-monosilane (ifomula yamakhemikhali i-SiH4) ngokuthi “i-silane”.

Ibanga le-elekthronikhiigesi ye-silaneItholakala kakhulu ngokuhluzwa okuhlukahlukene kokusabela kanye nokuhlanzwa kwempuphu ye-silicon, i-hydrogen, i-silicon tetrachloride, i-catalyst, njll. I-Silane enokuhlanzeka okungu-3N kuya ku-4N ibizwa ngokuthi i-silane yezinga lezimboni, kanti i-silane enokuhlanzeka okungaphezu kuka-6N ibizwa ngokuthi igesi ye-silane yezinga le-electronic.

Njengomthombo wegesi wokuthwala izingxenye ze-silicon,igesi ye-silaneisibe igesi ekhethekile ebalulekile engenakushintshwa eminye imithombo eminingi ye-silicon ngenxa yobumsulwa bayo obuphezulu kanye nekhono lokufinyelela ukulawula okuhle. I-Monosilane ikhiqiza i-silicon ekristali nge-pyrolysis reaction, okwamanje ingenye yezindlela zokukhiqizwa okukhulu kwe-granular monocrystalline silicon kanye ne-polycrystalline silicon emhlabeni.

Izici zeSilane

I-Silane (SiH4)iyigesi engenambala ephendula emoyeni futhi ibangele ukuminyana. Igama layo elifanayo yi-silicon hydride. Ifomula yamakhemikhali ye-silane yi-SiH4, futhi okuqukethwe kwayo kuphakeme njengo-99.99%. Emazingeni okushisa nokucindezela kwegumbi, i-silane iyigesi enobuthi enuka kabi. Indawo yokuncibilika kwe-silane ingu-185℃ kanti indawo yokubila ingu-112℃. Emazingeni okushisa egumbi, i-silane izinzile, kodwa uma ishiswa ku-400℃, izobola ngokuphelele ibe yi-silicon ne-hydrogen egesi. I-Silane iyavutha futhi iyaqhuma, futhi izosha kakhulu emoyeni noma kugesi we-halogen.

Izinkambu zohlelo lokusebenza

I-Silane inezindlela eziningi zokusebenzisa. Ngaphezu kokuba yindlela ephumelela kakhulu yokunamathisela ama-molecule e-silicon ebusweni beseli ngesikhathi sokukhiqizwa kwamaseli elanga, isetshenziswa kabanzi nasezitshalweni zokukhiqiza ezifana nama-semiconductor, ama-flat panel displays, kanye nengilazi embozwe ngendwangu.

I-Silaneingumthombo we-silicon wezinqubo zokufaka umphunga wamakhemikhali njenge-single crystal silicon, ama-polycrystalline silicon epitaxial wafers, i-silicon dioxide, i-silicon nitride, kanye nengilazi ye-phosphosilicate embonini ye-semiconductor, futhi isetshenziswa kabanzi ekukhiqizweni nasekuthuthukisweni kwamaseli elanga, ama-drum e-silicon copier, izinzwa ze-photoelectric, imicu ye-optical, kanye nengilazi ekhethekile.

Eminyakeni yamuva nje, ukusetshenziswa kwe-silane ngobuchwepheshe obuphezulu kusavela, okuhlanganisa ukukhiqizwa kwezinto zobumba ezithuthukisiwe, izinto ezihlanganisiwe, izinto ezisebenzayo, izinto eziphilayo, izinto ezinamandla aphezulu, njll., okuba yisisekelo sobuchwepheshe obusha obuningi, izinto ezintsha, namadivayisi amasha.
