Yintoni iSilicon Carbide (SiC) Crucible?
I-Silicon Carbide Crucible sisikhongozeli se-ceramic esisebenza kakuhle esenziwe ngezinto ze-SiC ezicocekileyo kakhulu. Yenzelwe ngokukodwa ukusebenza phantsi kweemeko ezishushu kakhulu kunye neekhemikhali apho izinto zesiqhelo zinokungaphumeleli khona. I-Silicon carbide inika indibaniselwano eyahlukileyo yokumelana nobushushu obuphezulu, ukuqhuba kakuhle kobushushu, amandla aphezulu oomatshini, kunye nokungangeni kakuhle kweekhemikhali. Ezi mpawu zivumela ii-SiC crucibles ukuba zigcine ukuthembeka kwesakhiwo kunye nozinzo olulinganayo nokuba zichatshazelwe kumaqondo obushushu angaphezulu kwe-1,600°C, nto leyo eyenza ukuba zilungele ukusetyenziswa kwemveliso ye-semiconductor ephucukileyo.
Ukusetyenziswa okuqhelekileyo kweeSiC Crucibles kwiMveliso yeSemiconductor
Enye yezona zinto zibalulekileyo ezisetyenziswayo kwii-crucibles zeSiC kukukhula kwekristale. Kwimveliso yee-substrates ze-silicon carbide, umgubo we-SiC ococekileyo kakhulu ufudunyezwa ukuya kumaqondo obushushu aphezulu kakhulu, apho i-sublimation kunye ne-recrystallization zenzeka khona ukuze zenze iikristale ezizodwa. Kuyo yonke le nkqubo, i-crucible isebenza njengesakhiwo esiphambili sokukhusela, ibonelela ngendawo elawulwayo yobushushu exhasa ukwakheka kwekristale ngelixa inciphisa umngcipheko wongcoliseko. Umgangatho we-crucible unokuchaphazela kakhulu uxinano lweziphene, ukufana kwekristale, kunye nokuveliswa kwe-wafer.
Ngaphaya kokukhula kwekristale yeSiC, ii-silicon carbide crucibles zisetyenziswa kakhulu ekuvelisweni kwee-semiconductors ezidityanisiweyo, kubandakanya i-gallium nitride (GaN), i-aluminium nitride (AlN), kunye nezinye izinto eziphambili ezisetyenziswa kwizixhobo ze-elektroniki ezinamandla kunye nezixhobo ze-optoelectronic. Ukumelana kwazo okuhle kakhulu ne-corrosive process chemistryries kunye ne-thermal shock kuzenza zilungele iinkqubo ezahlukeneyo ze-vapor phase yobushushu obuphezulu kunye ne-physical vapor transport (PVT). Ukongeza,Ii-crucibles zeSiCZisetyenziswa rhoqo kwiinkqubo zokufuma, ukwenziwa kwezinto ezisebenzisa ubushushu obuphezulu, kunye nokulungiswa okukhethekileyo kweseramikhi apho ulawulo longcoliseko kunye nokufana kobushushu kuyimfuno ebalulekileyo.
Iingenelo zobunjineli zeSiC Crucibles
Ngokwembono yobunjineli, iingenelo zee-silicon carbide crucibles zidlula kakhulu ukumelana nobushushu obulula. Ukuqhuba kwazo ubushushu obuphezulu kunceda ekudaleni ukusasazwa kobushushu obufanayo kulo lonke igumbi lenkqubo, kunciphisa i-thermal gradients enokuba negalelo kwiziphene zekristale okanye ukungangqinelani kwezinto. Uzinzo lwazo olukhethekileyo lweekhemikhali lunciphisa iimpendulo ezingafunekiyo phakathi kwe-crucible kunye nezixhobo zenkqubo, kunceda ukugcina amanqanaba aphezulu kakhulu okucoceka afunekayo kwimveliso ye-semiconductor yanamhlanje. Ngaphezu koko, amandla oomatshini e-SiC axhasa ubomi obude benkonzo, nokuba phantsi kweemeko zokujikeleza kobushushu obuphindaphindeneyo, okufaka isandla ekunciphiseni iindleko zolondolozo kunye nokusebenza kakuhle kwemveliso.
Izinto Omele Uziqwalasele Xa Usebenzisa iiSiC Crucibles
