Silane (SiH4)

Ma'aunin Fasaha

Silane wani fili ne na silicon da hydrogen. Kalma ce ta gaba ɗaya don jerin mahadi, gami da monosilane (SiH4), disilane (Si2H6) da wasu mahaɗan siliki-hydrogen mafi girma. Daga cikin su, monosilane shine ya fi kowa, wani lokaci ana kiransa silane a takaice. Silane iskar gas ce mara launi tare da warin tafarnuwa mai banƙyama. Mai narkewa a cikin ruwa, kusan maras narkewa a cikin ethanol, ether, benzene, chloroform, silicon chloroform da silicon tetrachloride. Abubuwan sinadarai na silanes sun fi aiki fiye da alkanes kuma suna da sauƙin oxidized. Konewar kai tsaye na iya faruwa lokacin da ake hulɗa da iska. Ba ya amsa tare da nitrogen da ke ƙasa da 25 ° C, kuma baya amsawa tare da mahadi na hydrocarbon a zafin jiki. Wuta da fashewar silane sune sakamakon amsawa tare da iskar oxygen. Silane yana da matukar damuwa ga iskar oxygen da iska. Silane tare da wani takamaiman maida hankali shima zai mayar da martani da fashewa da iskar oxygen a zazzabi na -180°C. Silane ya zama mafi mahimmancin iskar gas na musamman da aka yi amfani da shi a cikin matakai na microelectronics na semiconductor, kuma ana amfani dashi a cikin shirye-shiryen fina-finai na microelectronic daban-daban, ciki har da fina-finai na crystal guda ɗaya, microcrystalline, polycrystalline, silicon oxide, silicon nitride, da silicides na karfe. Aikace-aikacen microelectronic na silane har yanzu suna tasowa cikin zurfi: ƙananan zafin jiki na epitaxy, zaɓaɓɓen epitaxy, da heteroepitaxial epitaxy. Ba wai kawai don na'urorin silicon da haɗin haɗin gwiwar silicon ba, har ma don na'urorin semiconductor (gallium arsenide, silicon carbide, da sauransu). Hakanan yana da aikace-aikace a cikin shirye-shiryen kayan rijiyar superlatice quantum. Ana iya cewa ana amfani da silane a kusan dukkanin layukan samar da da'ira na ci gaba a wannan zamani. Aikace-aikacen silane a matsayin fim ɗin da ke ɗauke da siliki da sutura ya haɓaka daga masana'antar microelectronics na gargajiya zuwa fannoni daban-daban kamar ƙarfe, injina, sinadarai da na gani. Wani yuwuwar aikace-aikacen silane shine kera sassan injin yumbu mai inganci, musamman amfani da silane don kera silicide (Si3N4, SiC, da sauransu) fasahar micropowder ta jawo hankali sosai.

Aikace-aikace:

① Lantarki:

Ana amfani da Silane akan yaduddukan siliki na polycrystalline akan wafers na siliki lokacin kera semiconductor, da masu ɗaukar hoto.

②Solar:

Ana amfani da Silane a masana'anta na hotovoltaic na hasken rana.

③ Masana'antu:

Ana amfani da shi a cikin Gilashin Green mai ceton Makamashi kuma ana amfani da shi ga tsarin yin fim na bakin ciki.
