ISilane (SiH4)

Iiparameters zobugcisa

ISilane yintlanganisela yesilicon kunye nehydrogen. Ligama eliqhelekileyo loluhlu lweekhompawundi, kuquka i-monosilane (SiH4), i-disilane (Si2H6) kunye nezinye iikhompawundi zesilicon-hydrogen ezikumgangatho ophezulu. Phakathi kwazo, i-monosilane yeyona ixhaphakileyo, ngamanye amaxesha ibizwa ngokuba yi-silane ngamafutshane. I-Silane yigesi engenambala enevumba elibi legalikhi. Inyibilika emanzini, phantse inganyibiliki kwi-ethanol, i-ether, i-benzene, i-chloroform, i-silicon chloroform kunye ne-silicon tetrachloride. Iipropati zeekhemikhali ze-silane zisebenza kakhulu kune-alkanes kwaye zinyibilikiswa lula. Ukutsha okuzenzekelayo kunokwenzeka xa kudibene nomoya. Ayiphenduli ne-nitrogen engaphantsi kwama-25°C, kwaye ayiphenduli neekhompawundi ze-hydrocarbon kubushushu begumbi. Umlilo kunye nokuqhuma kwe-silane ziziphumo zokusabela ne-oxygen. I-Silane inovakalelo olukhulu kwi-oxygen nomoya. I-Silane enoxinzelelo oluthile iya kusabela kakhulu ne-oxygen kubushushu obuyi--180°C. I-Silane ibe yeyona gesi ikhethekileyo ibalulekileyo esetyenziswa kwiinkqubo ze-semiconductor microelectronics, kwaye isetyenziswa ekulungiseleleni iifilimu ezahlukeneyo ze-microelectronic, kubandakanya iifilimu ze-single crystal, i-microcrystalline, i-polycrystalline, i-silicon oxide, i-silicon nitride, kunye ne-metal silicides. Ukusetyenziswa kwe-microelectronic ye-silane kusaphuhla nzulu: i-epitaxy yobushushu obuphantsi, i-epitaxy ekhethiweyo, kunye ne-heteroepitaxial epitaxy. Ayizizo kuphela izixhobo ze-silicon kunye neesekethe ezihlanganisiweyo ze-silicon, kodwa nakwizixhobo ze-compound semiconductor (gallium arsenide, i-silicon carbide, njl.njl.). Ikwanokusetyenziswa ekulungiseleleni izixhobo ze-superlattice quantum well. Kunokuthiwa i-silane isetyenziswa phantse kuzo zonke iindlela zokuvelisa iisekethe ezihlanganisiweyo eziphambili kwixesha lanamhlanje. Ukusetyenziswa kwe-silane njengefilimu kunye nokwaleka okuqulethe i-silicon kuye kwanda ukusuka kushishino lwe-microelectronics yendabuko ukuya kwiindawo ezahlukeneyo ezifana nentsimbi, oomatshini, iikhemikhali kunye ne-optics. Olunye ukusetyenziswa kwe-silane kukwenziwa kwezixhobo ze-ceramic engine ezisebenza kakhulu, ngakumbi ukusetyenziswa kwe-silane ukwenza i-silicide (Si3N4, SiC, njl.njl.) itekhnoloji ye-micropowder itsala ingqalelo engakumbi.

Isicelo:
