Silane (SiH4)

Sigogi na Fasaha

Silane wani sinadari ne na silicon da hydrogen. Kalma ce ta gabaɗaya ga jerin sinadarai, waɗanda suka haɗa da monosilane (SiH4), disilane (Si2H6) da wasu sinadarai masu ƙarfi na silicon-hydrogen. Daga cikinsu, monosilane shine mafi yawan gaske, wani lokacin ana kiransa silane a takaice. Silane iskar gas ce mara launi tare da ƙamshi mai ban ƙyama na tafarnuwa. Yana narkewa a cikin ruwa, kusan ba ya narkewa a cikin ethanol, ether, benzene, chloroform, silicon chloroform da silicon tetrachloride. Halayen sinadarai na silanes sun fi alkanes aiki kuma ana iya yin oxidize cikin sauƙi. Konewa kwatsam na iya faruwa lokacin da ya haɗu da iska. Ba ya amsawa da nitrogen ƙasa da 25°C, kuma baya amsawa da mahadi na hydrocarbon a zafin ɗaki. Wuta da fashewar silane sakamakon amsawa ne da oxygen. Silane yana da matuƙar saurin kamuwa da iskar oxygen da iska. Silane mai wani yawan abu zai kuma yi martani mai ƙarfi da iskar oxygen a zafin -180°C. Silane ya zama mafi mahimmancin iskar gas ta musamman da ake amfani da ita a cikin hanyoyin microelectronics na semiconductor, kuma ana amfani da ita wajen shirya fina-finan microelectronic daban-daban, gami da fina-finan kristal guda ɗaya, microcrystalline, polycrystalline, silicon oxide, silicon nitride, da silicide na ƙarfe. Aikace-aikacen microelectronic na silane har yanzu suna ci gaba da girma: epitaxy mai ƙarancin zafin jiki, epitaxy mai zaɓi, da epitaxy heteroepitaxial. Ba wai kawai ga na'urorin silicon da da'irorin silicon da aka haɗa ba, har ma ga na'urorin semiconductor masu haɗawa (gallium arsenide, silicon carbide, da sauransu). Hakanan yana da aikace-aikace a cikin shirya kayan rijiyar superlattice quantum. Ana iya cewa ana amfani da silane a kusan dukkan layukan samar da da'ira masu haɗaɗɗu a zamanin yau. Aikace-aikacen silane a matsayin fim da shafi mai ɗauke da silicon ya faɗaɗa daga masana'antar microelectronics ta gargajiya zuwa fannoni daban-daban kamar ƙarfe, injina, sinadarai da na gani. Wani amfani da silane zai iya yi shi ne ƙera sassan injinan yumbu masu inganci, musamman amfani da silane don ƙera silicide (Si3N4, SiC, da sauransu) fasahar micropowder ta jawo hankali sosai.

Aikace-aikace:

①Na'urar lantarki:

Ana amfani da Silane a kan yadudduka na silicon polycrystalline akan wafers na silicon lokacin ƙera semiconductors, da sealants.

②Rana:

Ana amfani da Silane wajen kera na'urorin hasken rana na photovoltaic.

③Masana'antu:

Ana amfani da shi a cikin gilashin kore mai adana kuzari kuma ana amfani da shi a cikin tsarin fim ɗin ɓoye tururi.
