I-6inch SiC Epitaxiy wafer N/P uhlobo lwamkele olulungiselelweyo
Inkqubo yokulungiselela i-silicon carbide epitaxial wafer yindlela yokusebenzisa i-Chemical Vapor Deposition (CVD) iteknoloji. Oku kulandelayo yimigaqo yobugcisa efanelekileyo kunye namanyathelo enkqubo yokulungiselela:
Umgaqo wobugcisa:
I-Chemical Vapor Deposition: Ukusebenzisa igesi ekrwada kwisigaba segesi, phantsi kweemeko ezithile zokusabela, iyabola kwaye ifakwe kwi-substrate ukwenza ifilimu enqwenelekayo.
Ukusabela kwesigaba segesi: Ngokusebenzisa i-pyrolysis okanye i-cracking reaction, iigesi ezahlukeneyo zezinto ezibonakalayo kwisigaba segesi zitshintshwa ngokwekhemikhali kwigumbi lokuphendula.
Amanyathelo enkqubo yokulungiselela:
Ukunyangwa kwe-substrate: I-substrate iphantsi kokucoca umphezulu kunye nokulungiswa kwangaphambili ukuze kuqinisekiswe umgangatho kunye ne-crystallinity ye-epitaxial wafer.
Ukulungiswa kwegumbi lokuphendula: lungisa ubushushu, uxinzelelo kunye nesantya sokuhamba kwegumbi lokuphendula kunye nezinye iiparameters ukuqinisekisa ukuzinza kunye nokulawulwa kweemeko zokusabela.
Unikezelo lwempahla ekrwada: nikezela ngezinto ezifunekayo zerhasi kwigumbi lokusabela, ukuxuba kunye nokulawula izinga lokuhamba njengoko kufuneka.
Inkqubo yokusabela: Ngokufudumeza igumbi lokusabela, i-gaseous feedstock ingena kwikhemikhali kwigumbi ukuvelisa idiphozithi oyifunayo, okt ifilimu yesilicon carbide.
Ukupholisa kunye nokukhulula: Ekupheleni kokusabela, ubushushu buyancipha ngokuthe ngcembe ukupholisa kunye nokuqinisa iidiphozithi kwigumbi lokuphendula.
I-Epitaxial wafer annealing kunye ne-post-processing: i-wafer ye-epitaxial egciniweyo ifakwe kwaye iqhutywe emva kokuphucula iimpawu zayo zombane kunye ne-optical.
Amanyathelo athile kunye neemeko zenkqubo yokulungiselela i-silicon carbide epitaxial wafer inokwahluka ngokuxhomekeke kwisixhobo esithile kunye neemfuno. Oku ngasentla kuphela ukuhamba kwenkqubo ngokubanzi kunye nomgaqo, umsebenzi othile kufuneka ulungelelaniswe kwaye uphuculwe ngokweyona meko.
